X-ray angiography directly to good effect in breast cancer screening

X-ray contrast media is directly the best way to check for breast cancer,has become popular for use in home and abroad. 
Breast (x-ray machine)X-ray angiography is the best means of breast cancer screening and early diagnosis.Canadian researchers report that on the 14th,there are two digital breast X-ray angiography for use in direct digital radiography (DR) screening is better than a computer X -ray contrast (CR). 
Angiography difference between the two is that similar to a digital camera directly to angiography,the radiologist can instantly via computer image analysis;while the computer angiography breast image information is recorded in a contrast panel,read by the reading device,the computer processing an image is formed. 
 
Ontario,Canada"Cancer Care Ontario"project researchers in the American Journal of the 14th issue of"Radiology"the report said,breast cancer screening in Ontario in addition to two digital (portable x-ray machine)X-ray angiography,as well as the use of traditional film X line angiography.810,000 times their breast cancer screening from 2008 to 2009 in the province of more than 680,000 women were surveyed.It was found that direct digital radiography and conventional film angiography screening effect is quite,but the detection rate of breast cancer is relatively low computer angiography. 
Typically,every 1000 women receiving breast (mobile x-ray machine)X-ray angiography screening will find less than five cases of breast cancer.Study reported that the use of computers angiography,per 10,000 women screened will be less about 10 cases of breast cancer screening.

How Long Are Premature Babies Kept in Incubators?

There is no set amount of time for a premature baby to stay in an incubator. Hospitals place most very premature babies or sick babies on open warming beds shortly after birth, so that it is easier to assess them and work on them. Once the baby needs fewer interventions, he generally goes into an incubator, which is an enclosed space that keeps him warm. Once he can maintain his temperature, he will go into an open crib -- the final step before coming home. How long the process takes depends on your baby. 
 
Temperature Stability 
The key to making the move from incubator to open crib is your baby's ability to maintain his temperature on his own in room air. Because premature babies do not have as much brown adipose tissue, a type of baby fat or as much subcutaneous fat as full-term babies do, they have more difficulty maintaining their temperature without a heated environment. Premature infants also experience insensible water loss from their increased surface area; keeping them in an incubator reduces fluid loss. 
Weight 
Your baby's weight helps determine when he is ready to try a move to an open crib. Many hospitals consider that a baby is able to try an open crib once he reaches 1,700 to 1,800 grams, or between 3 pounds, 12 ounces to 3 pounds, 15 ounces, according to an Australian study published in the 2011 "Cochrane Neonatal Reviews." After a review of available studies, the researchers concluded that hospital staff can safely move premature infants to an open crib when they weigh at 1,600 grams, or 3 pounds, 8 ounces -- or possibly, even less. 
Gestational Age 
Babies start to produce brown adipose tissue, or BAT, between the gestational age of 26 to 30 weeks, according to Birth.com. By 40 weeks, healthy newborns have enough BAT to maintain their temperatures in normal indoor temperatures without difficulty. Sometime between these two points, your baby will be ready for an open crib, but his current weight and medical conditions will determine when he is ready. 
Other Factors 
Infections, illness and stress can affect your preemie's ability to maintain his temperature adequately. Because of this, he might need to remain in an Cheap Isolettes even though he weighs as much as a normal full-term baby. A baby who cannot maintain his temperature might not gain weight as well as a baby kept in an incubator, because he uses up additional energy keeping his temperature stable.

Eight surgical shadowless advantage-Part I

Eight surgical shadowless advantage-on the articles.

Is a very important surgical shadowless lighting operation.It is used for special operations in the lighting,the surgical safety,quality of surgery,surgical efficiency and the ability to continue to work for the surgeon,eye health has a significant impact.With the development of the cause of medical care,surgical shadowless proposed new requirements.As ideal surgical shadowless should meet the following conditions(bovine ultrasound machine). 

A good shadowless effect

Usually surgical lamps called surgical light.This is a few dozen or a ring light evenly ball 50 to 100 cm in diameter in the shade device.Players using a special light bulb and reflector,the light source gathered from various angles in a subject according to the surface.This object is illuminated under shadowless encountered staggered interaction of light,reflected in the shadow of irradiated surface becomes extremely slight ghost,get a clear surgical field during surgery.As surgical shadowless lamp must have a good effect.Shadowless degree is an important feature and performance indicators surgical lamp.Any shadows in the surgical field will hinder the formation of the surgeon's observation,identification and surgery.Ideal surgical lamp in addition to providing adequate illumination,shall shadowless must have a high degree of assurance the surgical field surface and organizations have a deep luminosity.Part of the operation shadowless lamp see diagram.
 

Second,according to high

Surgery is the most intense visual task.Task lighting should be high illumination to reduce visual fatigue and improve work efficiency.About fine job lighting standards,national regulations vary.Depending on the object to another is less than 0.15 mm in diameter,for example,France is 1200 lux,Germany 2000 lux,3000 lux Britain,the United States 5000 to 10,000 lux,Japan 700 to 1500 lux,lux country is tentatively scheduled for 2000.Different surgical site,and some deep body cavity surgery,requires concentrating well,according to high,according to the Japanese Industrial Standard JISZ9110~1969,the provisions in the surgical field diameter of 30 cm range illumination of 2000 lux.High intensity surgical lights must have the condition.Recently,the Japanese developed a surgical light illumination of up to 2,000,000 lux.As surgical lighting,most countries believe that to 60,000 to 100,000 lux illumination is appropriate,the equivalent of direct sunlight at noon in summer outdoor illumination is too bright can affect vision.Provide adequate illumination at the same time,to avoid glare on the beam surgical instruments.Glare affect vision and visual,easy to make eye fatigue,is not conducive to the smooth progress of surgery.Illumination and hand surgery room 's overall illumination lamp should be a certain percentage of the illumination should not differ between the two Mrs.America provisions in the operating room illumination than 1000 lux.Japan provided the overall lighting illumination is 1:10 local lighting illumination,that the overall illumination of the operating room should be above 1000 lux. 

Third,the low temperature heat less

With the improvement of illumination,and improve the beam will cause the temperature of the lamp body.Direct thermal beam head surgeon and surgical site tissue surgical lights will affect the efficiency and quality of operation surgery.To this end,the world attach great importance to this issue,and constantly develop new surgical lights,efforts aimed at reducing the temperature of the lamp.Recently,the French developed into a theater with a new cold light projection lamp.The lamp comprises an optical system and a number of cold mirrors.Using this light,compared with all previous surgery lighting equipment.Produce a stronger light,and heat was small.Due to the characteristics of the cold mirror,the incident light is only visible light region,the absolute output of the lamp is cold output.Up to 135,000 lux of illumination by changing the size and the focus position of the illumination area.In recent years,the use of chemical drugs,alternating layers of plating method on complex reflector(automatic x ray film processor) to heat and condenser.Again in front of the lamp assembly a heat wave reflection coated film complex devices.Visible light generated by the light source may be filtered through the infrared reflector 70%,most of the remaining infrared isolate and filter glass.After the above process called optical Cambodia cold.This cold surgical lights,heat not only small and high illumination,is an ideal surgical lighting equipment.Being finalized publication"People's Republic of China national military standard GJB-87 field lights," clearly stipulates the surgical field temperature:Run field surgical lights should not exceed 4C; portable field surgical lights should not exceed 6C. 

Fourth,good color effect light

The so-called surgical lighting color effect,provided that the beam can truly reflect the current blood(hematology analyzer),tissue and change the color.Same color object under light irradiation with different spectral power distributions show different colors.Color light show illuminated object color performance is called the light source.Surgical light required,not only to see the color of blood,and must be able to clearly distinguish the change of color and changes in blood tissue.Requires surgical lamp light source with excellent color rendering.Under incandescent seen with blood seen under a fluorescent color is different.Nature of the object is determined by the color of the color of the light source.Provisions of the international reference source CRI of 100.High color rendering index,color distortion less,that color is a good source;while the lower CRI,the more serious distortion,color of the light source that is not good.For example: incandescent bulbs and halogen tube general color rendering index of 95 to 99 ),with fluorescent tubes general color rendering index of 65-80).Color rendering and color temperature of the light source are closely related.Object emits a high temperature heat and light conditions,and changing the light color temperature.Light color available color temperature,the unit is the absolute temperature K.6000K color temperature required to achieve the true color of about 70 to 90,the effective color is close to 100.
