摘要：

We developed an ultrasonic dynamic imaging system to obtain a three-dimensional echogram in a blood vessel. The method makes it possible to detect the echo signal from objects instantaneously without scanning an ultrasonic beam using a ring array probe. First, we examined the spatial resolution. Second, we performed experiments using a butter block and a copper plate. The results show that this system has a spatial resolution below 1.0 mm, and also that a butter block in a plastic tube and a moving copper plate can be detected by this system.
