An ultrasonic imaging apparatus having an ultrasonic transducer for applying an ultrasonic beam to a subject, thereby to perform sector scanning. Echo waves are obtained by the sector scanning. The transducer converts the echo waves into echo signals. Echo signals are sampled at intervals shorter than the pitch of pixels. The data sampled along each scanning line is stored as pixel data in a frame memory comprising a number of memory elements. In this case, the data sampled at the points of the adjacent scanning lines, which are equidistant from a beam-emitting point, are used for obtaining interpolation data to be stored in the memory elements between the adjacent scanning lines.
