摘要: In an ultrasonic imaging system, angiographic image of a blood vessel, equivalent to X-ray image, is produced in real time by utilizing IIR digital filter with ROM and frame memory. The system comprises: scanning unit for biological body under medical examination within three-dimensional plane involving the pulses obtain echo signals from reflected body; data producing plurality scanned about regard respective planes response signals; bloodflow-distribution storage temporarily storing data, while sequentially updating superimposing plural each other during predetermined period.
