Patent ID: 7927279

Claim:
A diagnostic ultrasound system comprising: a probe configured to measure a subject using ultrasound by bringing said probe into contact with a subject in a first state; a first image production means for producing a first image of said subject according to information sent from said probe; an image display means for displaying said first image produced by said first image production means; a second image production means for producing a second image of said subject according to information measured by bringing the probe into contact with said subject in a second state different from said first state in that pressure is applied to the subject; a distortion operation means for calculating distortion information on a desired region-of-interest in said second image corresponding to the desired region-of-interest on said first image; a display control means for controlling the display of the distortion information, which is calculated by said distortion operation means, on said image display means; a means for setting a reference information and the desired region-of-interest on said first image displayed by said image display means; a variation operation means for calculating a macro displacement, which is a positional change of the reference information set on said first image into a counterpart visualized in said second image, and for calculating a micro displacement, which is the deformation change of the region-of-interest in said first image into a counterpart visualized in said second image; and a means for displaying the relationship between said macro displacement and said micro displacement calculated by said variation operation means and the distortion information calculated by said distortion operation means.
