The apparatus and the method include acquiring a medical image including anatomical information about a subject, and calculating characteristics of a tissue in the subject, which may affect propagation of the ultrasound based on the medical image. The apparatus and method also determine a parameter of the ultrasound to create a focal point on the subject using the calculated characteristics, and generate the ultrasound according to the determined parameter. | 12-18-2014 |
20150051480 | METHOD AND SYSTEM FOR TRACING TRAJECTORY OF LESION IN A MOVING ORGAN USING ULTRASOUND - A method of tracing a movement trajectory of a lesion in a patient's internal structure, and a system for performing the same. The method includes generating an image showing a movement trajectory of a target portion that is a portion to be irradiated with a therapeutic wave, irradiating the internal structure with a tracking wave, determining a location of the target portion using a reflected wave, and determining whether the location of the target portion is within the movement trajectory. | 02-19-2015 |
