An ultrasonic enhanced-contrast imager includes an ultrasonic probe for transmitting an ultrasonic wave to an organism and receiving an ultrasonic wave from the organism, a transmitting section for transmitting an ultrasonic signal to the ultrasonic probe, a receiving section for processing a response signal ultrasonic wave received by the ultrasonic probe, a filter for extracting a specific frequency component from the processed response signal, a setting control section for setting a pass frequency band of the filter on the basis of a frequency band of the response signal from a contrast medium injected to the organism, and a control section for controlling the operation of the filter in the set pass band.
