  What is Ultrasound.....? Ultrasound is sound whose frequency is above the range of human hearing. Normally human haring sound range is 20 Hz to 20000 Hz and Ultrasound range is 1 MHz to 20 MHz. Basically sound waves are transmitted into the body and returning echoes can be collected to use form image of body part or that area of Body. What is Piezo-Electric Effect.....? Piezo-Electric effect is simple as converting electric energy into mechanical energy and mechanical energy into electric energy. When an ultrasound transducer produce sound waves in this condition energy conversion is done electric energy into mechanical energy and when its received an echo another conversion is happen that is mechanical energy into electric energy. What is Resolution in Ultrasound.....?    1. Contrast Resolution-          The ability of an ultrasound system to demonstrate differentiation between tissue having different characteristics. 2. Temporal Resolution- ...

  (A)  Signal Processing Board This board is used for signal processing of ultrasound its located in usg section without this board machine will not boot. This board transfer signal to PC section its only one board that communicate with PC side via token ring/i pass cable. it also process the data that collected from TR Boards. (B) TR(Transmission and Received) Board This Board is used for transmit and received signal from probe and send it to signal processing board. In machine we found multiple tr boards as per machine model and its configuration. In some machine transmit and received board both are different and separate function done of transmit and received. (C) Graphics Card This card is play important role in machine it can install externally also it available in some machine internally or onboard.
