Ultrasound diagnostic apparatus
First Claim
1. An ultrasound diagnosis apparatus comprising:
- an ultrasound probe;
a beam-former configured to scan an object to be examined with ultrasound waves through said ultrasound probe;
a B-mode processor configured to generate B-mode data on the basis of a reception signal output from said beam-former;
a power Doppler processor configured to generate power Doppler data on the basis of the reception signal output from said beam-former, the power Doppler data being generated on the basis of the reception signal acquired under transmission conditions that a burst wave number is equal or substantially equal to that for the B-mode data, and an ensemble number is set to one of 2 to 10; and
a synthesizer configured to generate 1-frame synthetic image data by synthesizing the B-mode data with the power Doppler data.

Abstract
An ultrasound diagnosis apparatus includes an ultrasound probe and a beam-former configured to scan an object to be examined with ultrasound waves through the ultrasound probe. A B-mode processor generates B-mode image data on the basis of a reception signal output from the beam-former. A power Doppler processor generates power Doppler data on the basis of the reception signal output from the beam-former. The power Doppler data is generated on the basis of the reception signal acquired under transmission conditions that the burst wave number is equal or substantially equal to that for the B-mode data, and the ensemble size is set to one of 2 to 10. The B-mode image data and power Doppler data are partly synthesized.
