Abstract :
It is shown that pulse Doppler CT (computerized tomography) leads to more complete flow images than conventional flow imaging does; not only forward and reverse flow directions but also transverse directions are registered and imaged using a suitable color code. Pulse Doppler CT is proposed in a real-time two-array made and in a non-real-time but more sensitive scanning mode, which also has higher resolution. The reconstruction procedure is illustrated. Also described is an experimental setup that was applied to basic real-time imaging experiments in the two-array mode with artificial objects in a water tank. It is concluded that the method promises advantageous application in blood vessel architecture imaging and organ perfusion observation
