The development and testing of ultrasonic two-dimensional (2-D) Doppler color-flow imaging instrumentation is described. An analog transmit-and-receive section and digital processing section are combined in a microprocessor-controlled system to produce real-time 2-D imaging of blood velocity superimposed on real-time 2-D images of cardiac anatomy. These composite images resemble cineangiographic images but provide greater detail in a tomographic plane. Moreover, the 2-D imaging technique offers the advantages of increased safety and convenience, and decreased cost in a noninvasive test.
