How Ultrasound Works

ultrasound machine 
he Ultrasound Machine
A basic ultrasound machine has the following parts:
.Transducer probe-probe that sends and receives the sound waves
.Central processing unit (CPU)-computer that does all of the calculations and contains the electrical power .supplies for itself and the transducer probe
Transducer pulse controls-changes the amplitude,frequency and duration of the pulses emitted from the transducer probe
.Display-displays the image from the ultrasound data processed by the CPU
.Keyboard/cursor-inputs data and takes measurements from the display
.Disk storage device (hard,floppy,CD)-stores the acquired images
.Printer-prints the image from the displayed data

The transducer probe is th-e main part of the ultrasound machine.The transducer probe makes the sound waves and receives the echoes.It is,so to speak,the mouth and ears of the ultrasound machine(handheld ultrasound).The transducer probe generates and receives sound waves using a principle called the piezoelectric (pressure electricity) effect,which was discovered by Pierre and Jacques Curie in 1880.In the probe,there are one or more quartz crystals called piezoelectric crystals.When an electric current is applied to these crystals,they change shape rapidly.The rapid shape changes,or vibrations,of the crystals produce sound waves that travel outward.Conversely,when sound or pressure waves hit the crystals,they emit electrical currents.Therefore,the same crystals can be used to send and receive sound waves.The probe also has a sound absorbing substance to eliminate back reflections from the probe itself,and an acoustic lens to help focus the emitted sound waves. 
Transducer probes come in many shapes and sizes,as shown in the photo above.The shape of the probe determines its field of view,and the frequency of emitted sound waves determines how deep the sound waves penetrate and the resolution of the image.Transducer probes may contain one or more crystal elements;in multiple-element probes,each crystal has its own circuit.Multiple-element probes have the advantage that the ultrasounc beam can be "steered"by changing the timing in which each element gets pulsed;steering the beam is especially important for cardiac ultrasound (see Basic Principles of Ultrasound for details on transducers).In addition to probes that can be moved across the surface of the body,some probes are designed to be inserted through various- openings of the body (vagina,rectum,esophagus) so that they can get closer to the organ being examined (uterus,prostate gland,stomach);getting closer to the organ can allow for more detailed views.

The CPU is the brain of the ultrasound machine.The CPU is basically a computer that contains the microprocessor,memory,amplifiers and power supplies for the microprocessor and transducer probe.The CPU sends electrical currents to the transducer probe to emit sound waves,and also receives the electrical pulses from the probes that were created from the returning echoes.The CPU does all of the calculations involved in processing the data.Once the raw data are processed,the CPU forms the image on the monitor.The CPU can also store the processed data and/or image on disk. 
The transducer pulse controls allow the operator,called the ultrasonographer,to set and change the frequency and duration of the ultrasound pulses,as well as the scan mode of the machine.The commands from the operator are translated into changing electric currents that are applied to the piezoelectric crystals in the transducer probe.

Surface Engineered Surgical Tools and Medical Devices.

The barriers between nanotechnology and the marketplace lie in how to reduce the fabrication cost and how to integrate nanoscale assemblies with functional microscale and macro devices.Therefore,reliable mass production of nanostructures is currently one of the most crucial issues in nanotechnology.The commercialization of nanotechnology has to address the underlying necessities of predictability,repeatability,producibility and productivity in manufacturing at nanometer scale. 
Nanometric machining refers to a "top down" nanofabrication approach.To the authors' knowledge the concept of nanometric machining is more concerned with precision rather than the characteristic size of the product.Therefore,nanometric machining is defined as the material removal process in which the dimensional accuracy of a product can be achieved is 100 nm or less.Nanometric machining can be classified into four categories:Deterministic mechanical nanometric machining.This method utilizes fixed and controlled cutting tools,which can specify the profiles of three-dimensional components by a well-defined tool surface.The method can remove materials in amounts as small as tens of nanometers.It includes processes such as diamond turning,micro milling,and nano micro grinding. 
Loose abrasive nanometric machining.This method uses loose abrasive grits to removal a small amount of material.It consists of polishing,lapping,and honing,etc.Non mechanical nanometric machining comprises processes such as focused ion beam machining,micro-EDM,and excimer laser machining. 
Lithographic method.The method employs masks to specify the shape of the product.Two dimensional shapes are the main outcome; severe limitations occur when three dimensional products are attempted.Processes include X-ray(automatic x ray film processor) lithography,LIGA,and electron beam lithography.

Atomic Scale Machining of Surfaces Introduction.

Molecular dynamic simulations of machining at the atomic scale(lead door) can reveal a significant amount of information regarding the behavior of machining and grinding processes that cannot be explained easily using classical theory or experimental procedures.This chapter explains how the use of molecular dynamic simulations can be applied to the many problems associated with machining and grinding at the meso,micro,and nanoscales. 
lead lined door 
These include: (a) mechanics of nanoscale machining of ferrous and non-ferrous materials; (b) physics of nanoscale grinding of semiconductor materials; (c) effects of simulating a variety of machining parameters in order to minimize sub-surface damage; (d) modeling of exit failures experienced during machining such as burr formation and other dynamic instabilities during chip formation; (e) simulation of known defects in microstructures using molecular dynamic simulations,statistical mechanical,and Monte Carlo methods; (f) simulation of machining single crystals of known orientation; (g) extremely high speed nanometric cutting; (h) tool wear during machining; and (i) the effects of hardness on the wear of tool and workpiece materials.The nature of wear of the material ahead of the machining and grinding process,the variation of machining forces,and the amount of specific energy induced into the workpiece material using molecular dynamic simulations is discussed in this chapter. 
Nanotechnology is the creation and utilization of materials,structures,devices and systems through the control of matter at the nanometer length scale. 
The essence of nanotechnology is the ability to work at these levels to generate large structures with fundamentally new properties.Although certain applications of nanotechnology,such as giant magnetoresistance (GMR) structures for computer hard disk read head and polymer displays have entered the marketplace,in general nanotechnology is still at a very early stage of development.

Importance Of Keeping Medical Equipment Secure When Transporting

Medical equipment is very expensive.In many instances,it is hard to come by as well.This means that when you are transporting medical equipment in any way,it needs to be secure.Secure means making sure it doesn't break during transport and that it cannot be stolen in any way.Securing the medical equipments is of the utmost importance for various reasons to Sierra Cases as much as it is to you! 
Why You Need to Secure Medical Equipment 
It's important to secure medical equipment for a number of reasons.Some of the basic reasons include: 
-Protect investment 
-Avoid damage 
-Prevent theft 
-Ensure equipment is in working order upon arrival 
ultrasound machine 
You may need medical equipments based upon where you're going.For example,if you're with Doctors Without Borders,you may be taking portable diagnostic equipment to be able to help underdeveloped countries.If something happens to the diagnostic equipment during transport,you won't have access to another machine and you won't be able to help as many people as you had hoped to. 
There is a large black market for medical equipment and therefore you have to be careful against theft.Insuring your equipment can help to protect your investment but it may not prevent theft.This is why you have to secure the case itself with a lock to deter people from swiping it.If they don't think they can make a quick snatch and grab,they're less likely to bother. 
You need to ensure the equipment itself isn't going to break when it's in transport.You may be wheeling it onto a plane and storing it in the overhead or you may be strapping it to the hood of your Jeep.Whatever the method of transport is,you have to make sure you are doing all you can to make sure it doesn't break – and it all comes down to the right case. 
Some cases are better than others.It all depends on the equipment and the environment that you will be in during transport as well as for the duration of the trip.Especially when you are in Third World countries where transportation is not what it is in the United States and Europe,you have to be cautious about how you pack. 
How to Secure Medical Equipment 
Take the time to find cases that are designed for the medical equipment you will be transporting.You may have any number of medical machines with you.This can include such things as: 
-Portable X-ray machines
-Diagnostic tools
-Lab testing kits
-Monitors
-Computer equipment

Regardless of what you're carrying,you need to secure it.The equipment may not be able to come into contact with magnetic fields or x ray protection and this means you need to find a case that is impenetrable to these things.This will prevent any damage to the equipment itself. 
Whether you're in charge of carrying the cases from one location to another or you will be checking them onto a plane,putting them in the cargo hold of a bus,or even sending them by mail,you have to be sure they are not going to break within the case.This means you have to use caution when selecting a case.Be sure that you have a custom fit so that nothing is able to move around or hit another object.Vibrations can be very powerful and you don't want something to come unwrapped and break. 
Newer cases are made with Styrofoam and other materials that can be custom cut to fit an object inside.This ensures that the exact shape is accounted for so that nothing can move around or break.The way you put something in the case is the way it will remain through transportation until you open the case and remove the object. 
Medical equipment is too expensive and too hard to come by to not package it properly for transport.There are many reasons why it is important to secure it and plenty of ways for you to do so.Take the time to consider your options and consult a professional if necessary to be sure you are securing the equipment to the best of your ability.
