[Signal processing in ultrasound imaging, Doppler and Doppler imaging].
Ultraschall in der Medizin (Stuttgart, Germany : 1980), 1994The main purpose of signal processing in ultrasound imaging is the improvement of the image quality. The basics of three-dimensional, nonlinear image filtering are described in a simple way. For Doppler several million operations are computed per second to obtain the velocity distribution as a function of time.

A device and method for producing an image of a fluid moving through a medium. An acoustic wave insonifies the medium to produce Doppler shifted scattering from randomly located scatterers in the moving fluid. At least eight channels of acoustic detectors detect signals reflected from the medium and the amplitudes of the scattered signal is determined ...
