Description:
Within this module we develop and discuss an ultrasound imaging system block diagram so that the various system knobs, buttons, and controls can be understood in the greater context of the interactions that take place within the ultrasound system. Special attention is given to discussion regarding signal to noise ratio and averaging techniques in ultrasound. In addition to discussing the transmit power, receiver gain, time gain compensation, video compression, and data storage, we discuss some advanced system features such as compound imaging, spatial averaging, multiple transmit foci, and harmonic imaging.
