Abstract
Ultrasonic acoustic imaging finds many uses, particularly in the field of non-invasive medical testing. Detection of Doppler shifted acoustic frequencies permits observation of flow of a particle-containing liquid, for example, blood flow. In order to see slower moving blood by Doppler ultrasound investigation, as the blood moves from major blood vessels into arterioles and capillaries, it is necessary to lower the pulse repetition frequency. The herein disclosed invention is an interleaving technique that lowers the effective pulse repetition frequency at each probe position without exacting these system penalties.
