Medical ultrasound, also called diagnostic sonography or ultrasonography is a widely adopted diagnostic technique used for imaging of internal body structures like joints, muscles, tendons, and vessels. Ultrasound imaging technique aims for investigating the source of a particular disease and is considered to be gold standard to examine the fetal development of a pregnant. Ultrasonic imaging uses high frequency sound wave pulses sent into the tissue, which is assisted by a probe. These incident sound waves are reflected back at varying degrees and the echoes generated as a result of these reflections are recorded as displayed in the form of images called sonograms. This process is preferred over other imaging technologies due to its image provision in real time, portability of the probe, substantially lower imaging costs that a patient has to bear and non- harmful nature of the ionizing radiations. The ultrasound devices provides two dimensional images of blood flow motion, movement and location of specific molecules, tissue stiffness and the anatomy of a three dimensional interior organ of the body.
