Abstract
A scanning part ultrasonically scans a cross section of a subject corresponding to a frame period. The filter processor uses time-series received signals that are obtained from the scanning part corresponding to a plurality of frames to attenuate low-frequency components from the received signals of a plurality of locations within the cross section. The amplitude-comparator compares the amplitudes of the received signals with the amplitudes of the signals for which the low-frequency components have been attenuated, and the signals with smaller amplitudes are output. The image-generator generates morphological images of the subject based on the output signals from the amplitude-comparator.
Claims4
An ultrasonic imaging apparatus comprising:
- a scanning part configured to ultrasonically scan a cross section of a subject corresponding to a frame period;
- a filter-processor configured to use time-series received signals that are obtained corresponding to a plurality of frames from said scanning part to attenuate low-frequency components from the received signals of a plurality of locations within said cross section;
- an amplitude-comparator configured to compare the amplitudes of said received signals with the amplitudes of signals for which said low-frequency components have been attenuated to output signals in which said amplitudes are smaller;
- and
- an image-generator configured to generate morphological images of said subject based on output signals from said amplitude-comparator.
A control method for an ultrasonic imaging apparatus comprising:
- ultrasonically scanning a cross section of a subject corresponding to a frame period;
- using time-series received signals that are obtained corresponding to a plurality of frames at said scanning to attenuate low-frequency components from the received signals of a plurality of locations within said cross section;
- comparing the amplitudes of said received signals with the amplitudes of signals for which said low-frequency components have been attenuated to output signals in which said amplitudes are smaller;
- and
- generating morphological images of said subject based on the signals output as the result of said comparison.
