APPARATUS AND METHOD FOR ULTRASONIC COLOR IMAGING

This invention discloses a method and apparatus for ultrasonic color imaging applicable in medical diagnoses and industrial inspections. Multiple color parameters calculated via evaluating a plurality of characterizing properties of the ultrasonic signal attributable to an image point are employed to specify the color of the image point. The produced color image simultaneously exhibits the interior distributions of multiple physical properties of the target under ultrasound inspection, provides much richer interior information of the target than what traditional, single imaging parameter based ultrasonic imaging can provide. The invention enables far more and easier-to-perceive information to be communicated to image viewer's brain, significantly improves the efficiency of image reading, the capability of abnormality discrimination, and the accuracy and reliability of ultrasound inspection. While retaining the traditional capability of locating acoustic interfaces, the disclosed ultrasonic color imaging also provides an effective approach of expressing continuous acoustic medium bodies that prior arts were incapable of delivering.
