ULTRA SOUND IMAGING SIGNAL PROCESSING APPARATUS |
摘要 |
Provided is a signal processing apparatus including: an transducer that performs scanning over the interior of an object and acquires received waveform data of a plurality of scanlines; an intensity screening unit that outputs a high intensity position at which signal intensity calculated from the received waveform data is higher than a first predetermined value; a correlation calculation unit that calculates a correlation value in a constant-width division for received waveform data of a first scanline and of a second scanline having a predetermined correlation with the first scanline; a position extraction unit that extracts, as a candidate position of a singular region, a position which corresponds to a high intensity position and for which the correlation value is lower than a second predetermined value; and an image processor that performs signal processing of generating image data of the object on the basis of the received waveform data. |
