ABSTRACT:
In an illustrated embodiment, ultrasonic image processing equipment of the B scan type selectively supplies successive lines of an ultrasonic image signal to a signal mixer which also may receive a gray scale signal. Each successive ultrasonic field interval may thus have inserted therein a gray scale signal so that the ultrasonic display oscilloscope shows a flicker-free gray scale at one margin of the ultrasonic image display area, extending parallel to the line sweep direction (depth direction). By subjecting the gray scale signal to the video standards conversion and to the other transmission processes, e.g. photoelectric and photochemical conversion processes, used in video display and documentation, it is possible to prevent the loss of medically relevant information in these processes. The gray scale signal line or lines may alternate with the ultrasonic lines in each field interval so as to be recorded on magnetic tape, motion picture film and other media along with each ultrasonic image field.
