The invention of computers started the revolution of Information Technology in the world, bringing modern concepts into the world. In the past few decades, offices, factories and business adopted computers to enhance their performance. The next were the households to adopt the computers as their new form of entertainment. Today, computers, along with Internet technology are being introduced into hospitals to enhance the performance of the medical facilities that are dispensed.
The importance of computer is medicine is growing and spreading rapidly. The only disadvantage is perhaps that a full installation of all the computerized systems in hospitals is a lengthy and costly process. There are, however, some hospital systems which already work on the basis of computers. Here’s an explanation to all such systems as work on computers.
Medical Data
Every day hospitals and clinics which are attached to them churn out enormous volumes of data regarding patients, ailments, prescriptions, medications, medical billing details, etc. Such medical records are now all recorded into a medical billing software. Such mammoth databases are known as Electronic Medical Records and Electronic Health Records. These databases are operated by a set of computers and servers, and come in handy during medical alerts and emergencies. The concept of EHR is a bit broader than the EMR, as the database is accessible from different clinics and hospital. Thus, a patient’s medical history can be retrieved from any hospital by medical practitioners.
Medical Imaging
“Tests” are medical procedures where specified components of the human body are scanned. A test can be as simple as a regular blood test or it can be a complex CT scan. This process is often referred to as a medical imagery. In order to increase the precision of such procedures, computers have been adopted and integrated into the testing equipment. The cheap ultrasound machine and the MRI are the best examples, where computers have been adopted in order to the process faster and precise. Thus medical tests and have become more advanced as a result of the use of computers.
Medical Examination
Many systems are underway for the development of medical monitoring which will help humans to properly monitor their own health. In many cases doctors and surgeons also use sophisticated computer aided equipment to treat their patients. Such systems and procedures include bone scan procedure, prenatal ultrasound imaging, blood glucose monitors, advanced endoscopy which is used during surgery and blood pressure monitors. Basically these medical tests and tools provide significant convenience to medical practitioners. You will find that major laboratory equipment and heart rate monitors have already been computerized in many hospital.
Supply Inventory and Ordering
Inventories of hospital supplies can be tracked suing computer systems that alert employees to the need to place a new order. Orders and payments can also be submitted via computer, making the management of hospital supplies practical and efficient.
Research and Information
Doctors and nurses use hospital computers to research and verify information about illnesses, treatments and medications. Access to current medical research information empowers hospital health care professionals to provide effective patient care. Teaching hospitals also use computers as a resource for educating medical students about techniques and trends in all areas of medical specialization.
Communication
Doctors and nurses communicate with one another using hospital computer networks. Computers allow doctors to make adjustments to patient treatment plans via electronic communication. Hospital workers can also communicate with pharmacies and other health care agencies regarding prescriptions and patient needs.
There are significant advantages of using computers in hospitals. The importance of computers in hospital has also increased drastically due to the fact that the procedures have to be speedy to cater to a larger population and the medical services have to be more precise.
To sun up , the advantages of computers in hospitals can be summarized as follows:
Precise tests and medical examination
Faster medical alerts, which are more accurate and efficient
Enhanced data about a patient’s medical history
Precision in diagnosis
Precision in billing
Automated updating of medical history
The possibility of the uses of computers in the medical field is endless, facilitating medical help to hospitals and clinics all across the world. There’s no doubt that the elaboration of the uses of computers in hospitals is resourceful.

Computed Tomography Education And Study Guide
Here are computed tomography education. Let’s learning about Computed tomography study guide.
Computed tomography is a medical imaging method employing tomography created by computer processing. The word “tomography “is derived from the Greek tomos（slice ) and graphein.
A CT scanner is a special kind of x ray protection. Instead of sending out a single X-ray through your body as with ordinary X-rays, several beams are sent simultaneously from different angles. The X-rays from the beams are detected after they have passed through the body and their strength is measured. Beams that have passed through less dense tissue such as the lungs will be stronger, whereas beams that have passed through denser tissue such as as bone will be weaker. A computer can use this information to work out the relative density of the tissue examined. Each set of measurements made by the scanner is, in effect, a cross-section through the body. The computer processes the results, displaying then as a two-dimensional picture shown on a monitor.
The introduction of helical or spiral CT represents the most important step in the evolution of CT scanning technology in recent years. In older CT scanners, the X-rays source would move in a circular fashion to acquire a single “slice”. Once the slice had been completed, the scanner table would move to position the patient for the next slice; meanwhile the X-rays source/detectors would reverse direction to avoid tangling their cables. In helical CT the X-rays source are attached to a freely rotating gantry. During a scan, the table moves the patient smoothly through the scanner. The mane of helical CT derives from the helical path traced out by the X-ray beam. It was the development of slip ring technology that made helical CT practical. In the mid 1980’s,an innovation called the power slip ring was developed so that the X-ray cable could be abandoned. The slip ring allows electric power to be transferred from a stationary power source onto the continuously rotating gantry. CT scanners with slop rings can rotate continuously and do not have to slow down to start and stop.
The major advantage of helical scanning compared to the traditional CT, is speed; a large volume can be covered in 20~60 seconds. The scanning time is dramatically shortened. The patient can often hole their breath for the entire study, reducing motion artifacts. The data obtained and the increased resolution. These mew 3-D reconstruction techniques a number of noninvasive “virtual endoscopy “ procedures to be performed. These major advantages led to the rapid rise of helical CT as the most popular type of CT technology.
Although there are many different types of CT scanners , the basic parts of the equipment are the same and consist of a scanning gantry, a computer and a display console. The scanner consists of a moveable X-ray table and the scanner gantry. A X-ray source and an array of detectors, mounted within the gantry , rotate around the patient during each scan. The beam of X-ray is collimated before and after passing through the body. The detector records the attenuation values of the X-ray beam emerging form the patient.
Since its introduction in the 1970s, CT has become an important tool in medical imaging to supplement X-rays and medical ultrasonography. It has recently been used for preventive cheap medical equipment or screening for disease, for example CT colonography for patients with a high risk of coloncancer, or full-motion heart scans for patients with high risk of heart disease.Usage of CT has increased dramatically over the last tow decades. An estimated 72 million scans were performed in the United States in 2007. Not only very common in medicine, CT is also used in other fields, such as nondestructive materials testing.

Color Doppler Ultrasound Study
Color Doppler study is the main medical equipment study in science.
Color Doppler cheap ultrasound machine is a medical imaging technique which is used to provide visualization of the blood flow. Using color processing to add color to the image, a doctor or care provider can clearly see what is happening inside the body. This technique requires using of an ultrasound machine which is capable of color Doppler ultrasound. Having this imaging study performed is not usually painful, and the patient does not require sedatives.
Doppler ultrasound takes advantage of the Doppler effect to create a moving image of the inside of the body. In this technique, an ultrasound transducer is used to beam sound into the area of interest, and it reads the returning sound. When the sound bounces off a moving target like a blood vessel, the pitch changes as a result of the Doppler effect. The transducer can detect very subtle pitch change and record them visually, creating an image which shows where blood is flowing, and in which direction.
Viewed in grayscale, the image can be a bit hard to read. This is where color Doppler ultrasound comes in, with the ultrasound machine assigning color values which depend on whether blood is moving towards or away from the transducer, red and blue are usually be used. In addition to showing the direction of flow, the colors also vary in intensity depending on the velocity of the flow, allowing people to see how quickly the blood is moving.
One obvious application of color Doppler ultrasound is in examination of a patient with a suspected aneurysm of occlusion. The ultrasound will reveal areas where the velocity of the blood flow is changing, acting like a red flag to point out a problem. This technique can also be used to find blood clots, which will also be clearly visible within the color display.
In examination of rumors and venous malformations, doctors can use color Doppler ultrasound to map out the blood supply and learn how far the growth has spread. This can have an impact on which treatments the doctor recommends, and how the doctor wants to approach surgery and other measures.
While color Doppler ultrasound usually involves using a transducer on the outside of the body, it can be sued for transrectal procedures , in which the probe is inserted to get a better view. In these cases, patients may be given muscle relaxants so that the procedure will be less uncomfortable.
To ensure the best results when using the medical equipment, it is important to maintain a strict regular cleaning routine.
The most important part of the color Doppler ultrasound instrument(portable ultrasound machine) is the control system. The instrument usually has 4 types of controls, in addition to buttons on the transducers: keyboard panel controls (keys), controls on the careen, foot switch (optional), keys on the optional Palm control Unit (PCU).
The control panel is sealed underneath and is designed to resist limited amounts of liquid.
You should not pour liquids on it, however. The keyboard panel is not watertight. Be careful not to spill any liquids, gels or moist substances on the keyboard panel.
Clean the scanner, including the hand rest and keyboard panel, after every examination:
1, If necessary, remove the hand rest and clean it separately.
2, Use a soft cloth moistened with a mild detergent or a disinfectant.
3, Wipe dry with a lint-free cloth.
4, You can remove the holders for transducers and scanning gel from the scanner to clean them. The trackball can also be removed for cleaning.
It is necessary to know that although the scanner surface is resistant to many chemicals, strong chemicals may discolor it. To clean the PCU:
1, Make sure that the PCU is at room temperature.
2, Immediately rinse off any visible contamination (such as biological substances) with a detergent and tap water at a maximum temperature of 400C (1040F), using a brush if necessary, and keep all plugs and sockets absolutely dry at all times.

The transducer can detect very subtle pitch change and record them visually, creating an image which shows where blood is flowing, and in which direction.
Viewed in grayscale, the image can be a bit hard to read. This is where color Doppler ultrasound comes in, with the ultrasound machine assigning color values which depend on whether blood is moving towards or away from the transducer, red and blue are usually be used. In addition to showing the direction of flow, the colors also vary in intensity depending on the velocity of the flow, allowing people to see how quickly the blood is moving.
One obvious application of color Doppler ultrasound is in examination of a patient with a suspected aneurysm of occlusion. The ultrasound will reveal areas where the velocity of the blood flow is changing, acting like a red flag to point out a problem. This technique can also be used to find blood clots, which will also be clearly visible within the color display.
In examination of rumors and venous malformations, doctors can use color Doppler ultrasound to map out the blood supply and learn how far the growth has spread. This can have an impact on which treatments the doctor recommends, and how the doctor wants to approach surgery and other measures.
While color Doppler ultrasound usually involves using a transducer on the outside of the body, it can be sued for transrectal procedures , in which the probe is inserted to get a better view. In these cases, patients may be given muscle relaxants so that the procedure will be less uncomfortable.
To ensure the best results when using the medical equipment, it is important to maintain a strict regular cleaning routine.
The most important part of the color Doppler ultrasound instrument(portable ultrasound machine) is the control system. The instrument usually has 4 types of controls, in addition to buttons on the transducers: keyboard panel controls (keys), controls on the careen, foot switch (optional), keys on the optional Palm control Unit (PCU).
The control panel is sealed underneath and is designed to resist limited amounts of liquid.
You should not pour liquids on it, however. The keyboard panel is not watertight. Be careful not to spill any liquids, gels or moist substances on the keyboard panel.
Clean the scanner, including the hand rest and keyboard panel, after every examination:
1, If necessary, remove the hand rest and clean it separately.
2, Use a soft cloth moistened with a mild detergent or a disinfectant.
3, Wipe dry with a lint-free cloth.
4, You can remove the holders for transducers and scanning gel from the scanner to clean them. The trackball can also be removed for cleaning.
It is necessary to know that although the scanner surface is resistant to many chemicals, strong chemicals may discolor it. To clean the PCU:
1, Make sure that the PCU is at room temperature.
2, Immediately rinse off any visible contamination (such as biological substances) with a detergent and tap water at a maximum temperature of 400C (1040F), using a brush if necessary, and keep all plugs and sockets absolutely dry at all times.

Color Doppler cheap ultrasound machine is a medical imaging technique which is used to provide visualization of the blood flow. Using color processing to add color to the image, a doctor or care provider can clearly see what is happening inside the body. This technique requires using of an ultrasound machine which is capable of color Doppler ultrasound. Having this imaging study performed is not usually painful, and the patient does not require sedatives.
Doppler ultrasound takes advantage of the Doppler effect to create a moving image of the inside of the body. In this technique, an ultrasound transducer is used to beam sound into the area of interest, and it reads the returning sound. When the sound bounces off a moving target like a blood vessel, the pitch changes as a result of the Doppler effect.

Advances in Ultrasound Imaging Technology
Since the discovery of X-rays, two-dimensional (2-D) radiographic imaging has been the most widely used approach for ultrasound imaging anatomic structures, diagnosing disease, and guiding interventions . Unfortunately, 2-D X-ray imaging cannot provide physicians with a complete set of information fo imaging the human body.
Although 3-D CT, MRI, and X-ray techniques(x ray protection) are important imaging modalities, 3-D ultrasound machine has been shown to play a major role in medical diagnostics and minimally invasive image-guided interventions.
The basic concept of 3-D ultrasound is to collect a data of 2-D ultrasound images (black &white of color ) while tracking and storing the location of each individual 2-D image . The data set is then reconstructed into a single 3-D volume that can be displayed on the screen and manipulated. The reconstructed 3-D volume can be rotated, sliced, rendered or displayed in multiplanar cross-sections. Three-dimensional ultrasound imaging has provided high-definition images of complex anatomic structures and pathology to diagnose disease and to monitor and guide interventional procedures.
Although 2-D arrays are available for real-time 3-D imaging, most low-cost 3-D ultrasound(portable ultrasound machine) imaging systems use conventional one-dimensional (1-D) ultrasound transducers to acquire a series of 2-D US images. These images are reconstructed to form a 3-D image. A wide variety of approaches have been developed to determine the position and orientation of the 2-D images within the 3-D image volume. The production of a 3-D ultrasound image volume, without any distortions, requires that three factors be optimized:
The scanning technique must be either rapid (e. g., real time) or gated to avoid image artifacts due to involuntary, respiratory, or cardiac motion.
The locations and orientations of the acquired 2-D ultrasound image must be accurately known to avoid geometric distortions in the 3-D ultrasound image, which could lead to errors of measurement and guidance.
The scanning apparatus must be simple and convenient to use, so that the scanning process can be easily added to an examination or interventional procedure.
Because a set of 2-D ultrasound images is used to reconstruct the 3-D ultrasound image, the transducer must be moved so that the set of acquired 2-D ultrasound images covers the region of interest. However, a 2-D array allows the transducer to remain stationary , an electronic scanner is then used to sweep the ultrasound bean over the entire volume, allowing for the acquisition of a set of 3-D images to occur in real time (i.e. , 4-D ultrasound imaging ).
In this approach , a 2-D phased array of transducer elements is used to transmit a broadly diverging beam of ultrasound away from the array, sweeping out a volume shaped like a truncated pyramid. The returned echoes detected by the 2-D array are processed to display a set of multiple plane in real time . Using various image rendering techniques, user can interactively control and manipulate these planes to explore the entire volume. This approach is successfully used in echocardiography.
Many algorithms have been developed to help physicians and researchers visualize and manipulate 3-D medical images interactively. Because ultrasound image suffer from image speckle and poor tissue-tissue contrast, the display of a 3-D image plays a dominant role in the ability of physician to obtain valuable information.
Moreover, Doppler ultrasound technology also be developed, for example. Spectral Doppler scanning displays information about the spectrum of flow velocities as a function of time. It is sometimes called FFI (Fast Fourier Transform) because the information is presented as a frequency spectrum indicating velocity components.
