A differential amplitude or window discriminator is described which employs inexpensive integrated circuits and performs over an extremely wide frequency range (5 Hz-100 kHz for a sine-wave input). The discriminator can be employed in neurological st

Three methods of converting the Doppler signal to voltage proportional to mean velocity are compared. The traditional zero crosser is simple and reliable, however, erroneous readings are obtained in the presence of noise and broad band Doppler signal

The use of the pulsed Doppler velocity meter in cardiovascular applications has been restricted, due in part to difficulties in experimental usage of the device and systematic errors in signal processing, leading to inaccurate results. These problems

The detection of vortex trails and flow disturbances provides a means for transcutaneous detection of vascular obstructions. Downstream propagation of disturbances makes it possible to detect an obstruction without being directly over the obstruction

The measurement of blood velocity fields, volume flow, and arterial wall motion in the descending thoracic aorta provides essential hemodynamic information for both research and clinical diagnosis. The close proximity of the esophagus to the aorta in

Real-time cross-sectional echocardiography is developing rapidly as a noninvasive diagnostic technique for cardiac dysfunction. Using hand-held sector scanning probes, the heart can be rapidly surveyed for anatomical defects and abnormal motion. The
