Abstract :
There is a need for testing the performance of the color flow imaging systems in hospitals and manufacturing works. In view of the situation, we have discussed primary quantities which it would be desirable to measure the systems performance for clinical diagnosis and the test methods to measure the quantities. It has been decided that the following parameters are essential for clinical diagnosis using color flow imaging systems: 1) dead zone boundary; 2) penetration depth; 3)spatial resolution; 4) image uniformity; 5) tissue color suppression performance; 6) lowest detectable observed velocity; 7) highest detectable observed velocity; 8) temporal resolution. New types of phantoms for color flow imaging systems are presented.
