ABSTRACT:
An ultrasonic imaging arrangement. The arrangement includes a probe having an array of oscillators for emitting ultrasonic waves toward an object to be tomographically imaged, a first converter, a line memory group including a plurality of line memories, a write zoom operation unit, a frame memory, read zoom operation unit and a second converter. Echo signals reflected from the object are converted into digital signals as ultrasonic data. The ultrasonic data are stored in the line memory group, and are stored in the frame memory after processing operations in the write zoom operation unit. The read zoom operation unit then reads the data from the frame memory and, if necessary, processes that data. The second converter converts the processed data into video signals and a tomography image of the object is displayed according to the video signals.
