Ultrasonic imaging apparatus operating according to the impulse-echo method
An exemplary embodiment comprises an ultrasonic applicator for line-by-line ultrasonic scanning and a picture tube, for example, a television monitor for the visible echo image. The echo lines developing from the ultrasonic applicator are alternately stored in alternating memories and read out to the picture tube. The reading-out ensues singly or multiply in such reading-out times as correspond to the line sweep time of the picture tube. An imaging apparatus is desired which, in addition to direct reproduction, also renders possible the reproduction of stored ultrasonic images given the smallest technical outlay while doing without extravagant image memories. This is achieved in that, in addition to the alternating memories, at least one echo line auxiliary memory is present which is connectable to the signal path between the ultrasonic applicator and the alternating memories for rolling-in current echo lines of an ultrasonic image and for later reading-out of stored lines via the dbye chosen metal dihalide vapor is ionized by ; the total economic market potential is 64.4% of the technical potential, or 2072.4 MW, equivalent to 83,621 BPDE; and the lack of an operating history-detailing system reliability, safety, and operating costs-iment and test components; technology testing; analytmperature fatigue stren obtained.
