Abstract
An ultrasonic diagnostic apparatus according to one embodiment includes correlation matrix calculating circuitry, calculating circuitry, image generating circuitry, and controlling circuitry. The correlation matrix calculating circuitry calculates a correlation matrix of a scanned region consisting of a plurality of scan lines, from a data array of pieces of reflection wave data collected from the same position by transmitting and receiving ultrasonic waves in the scanned region across a plurality of frames. The calculating circuitry calculates a filter coefficient for suppressing a clutter generated by a tissue, by performing principal component analysis using the correlation matrix, and by performing a matrix operation of approximating a clutter component as a principal component and of suppressing the clutter component. The image generating circuitry generates ultrasound image data from blood flow information estimated using the filter coefficient. The controlling circuitry causes a display to display the ultrasound image data.
