First Claim
1. An ultrasonic diagnostic apparatus comprising:
- an ultrasonic probe;
a scanning unit configured to scan inside of an object administered with a contrast agent with an ultrasonic wave via the ultrasonic probe;
a signal generation unit configured to generate a quadrature detection signal based on a reception signal output from the scanning unit and output a packet signal constituted by the plurality of quadrature detection signals;
a first wall filter having a passband corresponding to a blood flow component included in the packet signal;
a second wall filter having a passband corresponding to a tissue perfusion component and blood flow component included in the packet signal;
a maximum value holding computation processing unit configured to apply maximum value holding computation processing to a first image corresponding to an output from the first wall filter; and
a display unit configured to display the first image having undergone the maximum value holding computation processing and a second image corresponding to an output from the second wall filter.

Abstract
According to one embodiment, a scanning unit scans the inside of an object administered with a contrast agent with ultrasonic waves. A signal generation unit outputs a packet signal based on the reception signal output from the scanning unit. A first wall filter has a passband corresponding to a blood flow component. A second wall filter has a passband corresponding to a tissue perfusion component and blood flow component. A maximum value holding computation processing unit applies maximum value holding computation processing to a first image corresponding to an output from the first wall filter. A display unit displays the first image having undergone maximum value holding computation processing and a second image corresponding to an output from the second wall filter.
