ABSTRACT:
In an ultrasonic computed tomography system including an image signal-processing apparatus for reconstructing an image signal of an object on the basis of a synthetic aperture technique, a probe includes a transducer unit. The transducer unit emits an ultrasonic beam to the object and detects the corresponding echo wave. Hologram data is produced in response to the echo wave and then digitized to have a predetermined number of bits by A/D converters. The digital hologram data is temporarily stored in buffer memories and read out under the control of a computer unit. The computer unit has a ROM assembled therein to prestore digital kernel function data, the number of whose bits is smaller than that of the digital hologram signals. The computer unit executes a convolution on the digital hologram data and the kernel function data, thus increasing the speed of a computation needed for image reconstruction.
