Sonography is portable, widely available, relatively inexpensive and safe. It does not use radiation.

In the ultrasound sonography, a transducer is connected with a receiver. Piezoelectric crystals in the signal generator to convert electricity into high frequency sound waves which are transmitted into the tissue. The tissue scatters, reflects and absorbs the sound waves in various degrees. The sound waves are reflected back (echo), and converted into electrical signals. A computer analyzes the signals and provides an anatomical recording on a screen. The ultrasound is portable, widely available, relatively inexpensive and safe. It does not use radiation. Using the ultrasound Ultrasound can superficial growths and identify foreign objects (eg. As in the thyroid, breast, testes, and some members lymph nodes). With deeper structures, other tissues and densities (z. B., bone, gas) affect the images. Ultrasound is commonly used to check the following: heart (echocardiography): To recognize, for example, abnormalities of the heart valves and chamber size and estimate ejection fraction and myocardial stress (echocardiography) gallbladder and biliary tract: eg. B. to recognize obstruction of gallstones and bile ducts (Imaging tests of the liver and gallbladder: sonography) urinary tract: eg, cysts (usually benign) of solid masses (often malignant) to distinguish or in the kidneys to detect obstructions, such as stones or other structural abnormalities in the kidneys, ureters or bladder (Imaging techniques for the genitourinary tract: ultrasonography) Female Reproductive System: in order to detect, for example, tumors and inflammation of the ovaries, fallopian tubes or the uterus (detect Imaging methods) pregnancy: for example, the growth and to evaluate the development of the fetus and to detect abnormalities of the placenta (placenta example previa- examination of the patient in obstetrics: sonography). Musculoskeletal: To evaluate muscles, tendons and nerves.
