Ultrasonography

Ultrasonography is also known as diagnostic sonography or medical solography’s a. Ultrasonography application of ultrasounds to form a diagnostic imaging, which is used to see internal body structure such as tendons, muscles, joints blood vessels. Its objective is to find the source of a disease or to exclude any pathology. The practice of examining pregnant women by using ultrasound is known as obestric ultrasound. Widely   used ultrasound sound waves with frequency of   >20,000HZ (higher than those audible to humans).

Ultrasonic images, also known as sonograms, are made by sending pulses of ultrasound into tissue using a probe. The sound echoes off the tissue; with different tissues reflecting varying degrees of sound. These echoes are recorded and displayed as an image to the operator. Different images are formed by sonographc instruments; most well-known image type is a B-mode image, in which acoustic impedance of a two-dimensional cross-section of tissue. Other types of image can display blood flow, motion of tissue over time, the location of blood, the presence of specific molecules, the stiffness of tissue, or the anatomy of a three-dimensional region.
