Direction of flow, Biology

Assignment Help:

Direction of flow--either towards or away from the transducer (positive or negative Doppler shifts).

Timing-instantaneous velocity and direction of flow throughout the various positions of cardiac cycle.

Intensity-the amplitude of individual velocities within the Doppler signal at any point of time-the more intense the signal, the greater number of blood cells moving at that velocity.
