Specificity.

A study was on the physical concepts ( transmission of sound waves among different parts of the body for medical diagnosis purposes )  , methods of detection two dimensional 2D commonly used  , modern methods as color Doppler ( Duplex ) , in addition new techniques that have developed and used together with the device ,  such as ( contrast medium , catheters using techniques , guidance technique for therapeutic injections and  a sample taking purposes  (Biopsies) . The research included a study of a 50 clinical cases of different parts of the body, ages, gender over two months. After cases discussion showed that the device is useful as initial step and very sensitive tool in the medical clinical field, specifically if the new techniques are applied, in turn increase the benefits of the device, get good clinical results and finally minimize the ionizing radiation exposure of the other devices.
