Eliminating motion effects in medical images caused by physiological function

Abstract

Ultrasonic imaging methods are described for eliminating the effects of physiological motion such as respiratory motion from image data of a sequence of images which is to be used for quantified analysis such as time-intensity curve computation. A bright reflector in the images of the loop which exhibits motional effects such as cyclical variation in brightness or position from image to image is identified and its variation used to identify cycles of motion. A phase or range of phases of the cycles is identified. Images acquired during the identified phase or phase range of the motion cycles during the loop are then used for quantified processing.

Background technique [0004] International Patent Publication WO 2006 / 090309 (Bruce et al.) describes an ultrasound imaging technique for detecting lesions in the liver by using ultrasound contrast agents. A bolus of contrast medium is introduced into the body and the time it takes for the contrast medium to reach the liver is measured. When a bolus of contrast agent travels through the blood vessels of the body and begins to appear at a specific organ or location in the body, the establishment of contrast in the image is called "washin...
