摘要
An ultrasonic tomography apparatus has an ultrasonic transmitter for transmitting an ultrasound to an object body; an ultrasonic receiver for receiving ultrasound reflected from an object body and producing an ultrasonic signal; a filter for extracting components of the ultrasonic signal in at least two different frequency bands; and an image generator for generating an ultrasonic tomogram of the object body based on the extracted ultrasonic signal component in a first frequency band and the extracted ultrasonic signal component in one or more second frequency bands. The first frequency band centers on a frequency band at the time of transmission, and the second frequency band is shifted from the frequency band at the time of transmission.
