Abstract
An ultrasonic enhanced-contrast imager and method includes an ultrasonic probe for transmitting and receiving an ultrasonic wave to and from an 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, and 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. A control section controls the operation of the filter in the set pass band, and the setting control section sets the center frequency of the pass band of the filter to be greater than fand less than 2f, where fis the average frequency of the ultrasonic signal transmitted to the ultrasonic probe.
