METHOD OF GENERATING TEMPERATURE MAP SHOWING TEMPERATURE CHANGE AT PREDETERMINED PART OF ORGAN BY IRRADIATING ULTRASOUND WAVE ON MOVING ORGANS, AND ULTRASOUND SYSTEM USING THE SAME

摘要

A method of generating a temperature map showing a temperature change in a predetermined part by irradiating ultrasound waves on a moving organ includes generating reference frames indicating images of an observed part including a treatment part in the predetermined organ during a predetermined period related to a movement cycle of the predetermined organ from echo signals transduced from reflected waves of ultrasound waves for diagnosis irradiated on the observed part during the predetermined period; generating a current frame indicating an image of the observed part at a time an ultrasound wave for treatment is irradiated on the treatment part from the echo signals; selecting a comparison frame that is one of the reference frames based on a similarity between the reference frames and the current frame; and generating a temperature map showing a temperature change in the observed part based on a difference between the comparison and current frames.
