Abstract
A plurality of amplifiers amplify a plurality of received signals in accordance with a gain function that varies with a depth. A maximum amplitude detector detects a maximum amplitude at each depth from among the plurality of received signals. A gain function corrector corrects the gain function based on the maximum amplitude at each depth. A corrected gain function is applied to the plurality of amplifiers. A compensator performs gain compensation with respect to beam data.
Claims9
An ultrasonic diagnostic apparatus comprising:
- a plurality of amplifiers configured to amplify a plurality of received signals in accordance with a gain function that varies with a depth and to output a plurality of amplified received signals;
- a beamformer configured to apply delay to the plurality of amplified received signals and then add up a plurality of delayed received signals, thereby generating beam data;
- a detector configured to detect a representative value sequence comprising a plurality of representative values arranged in a depth direction, based on the plurality of amplified received signals or the plurality of delayed received signals;
- and
- a corrector configured to correct an original gain function based on the representative value sequence to thereby generate a corrected gain function, wherein
- the corrected gain function is applied to the plurality of amplifiers as the gain function.
