The detected Doppler shift frequency (fd) can be used to calculate the velocity of an object the waves reflect off using the ‘doppler equation’: v = flow velocity (m/s)c = the speed of sound in tissues (m/s)fd = Doppler frequency shift that is received...
Gain Focus Depth Dynamic Range Sector Width Frequency Describes the degree of amplification of the reflected signal that is receivedIf low gain is used, tissues which are poor reflectors will not be visualisedIf high gain is used noise is added to the image and it can...
