Abstract :
A quantitative performance model for power Doppler detection tasks is developed based on statistical decision theory. The model gives insights into optimizing power Doppler system designs. Flow-weighted and scatterer density weighted images can be formed by changing the pulse-repetition interval. Wideband pulses are seen to be best for clutter limited detection of blood while high amplitude or longer energy-rich pulses are better for noise-limited detection.
