Patent Images
1. An ultrasonic diagnostic apparatus comprising:
- a display device configured to display an ultrasonic image of a subject that has been given a contrast medium;
a setting device configured to set a region of interest in the ultrasonic image displayed by said display device; and
a computing device configured to compute a time intensity curve indicating time change in an average brightness of pixels in the set region of interest, wherein said computing device is further configured to exclude pixels corresponding to a non-observed object in the region of interest when computing the time intensity curve.

Abstract
An ultrasonic diagnostic apparatus includes a display device for displaying an ultrasonic image of a subject has been given a contrast medium, a setting device for setting a region of interest in an ultrasonic image displayed in the display device, and a computing device for computing a time intensity curve indicating time change in the average brightness of the pixels in a set region of interest. The computing device excludes pixels corresponding to a non-observed object in a region of interest when computing a time intensity curve.
