SYSTEM AND METHOD FOR NON-RIGID IMAGE MATCHING BETWEEN ULTRASOUND IMAGES AND CT IMAGES BY USING INTENSITY AND GRADIENT INFORMATION

摘要

PROBLEM TO BE SOLVED: To provide a system and method for non-rigid image matching between ultrasound images and CT images.;SOLUTION: The system for non-rigid image matching includes: an ultrasound image forming unit configured to transmit/receive ultrasound signals, and form 3-dimensional ultrasound images of a target object; a CT image forming unit configured to form the 3-dimensional CT images of the target object; and a matching unit configured to form first and second objective functions of a first region and a second region based on intensity and gradient information corresponding to the first and second regions and performs the non-rigid image matching of the 3-dimensional ultrasound images and the 3-dimensional CT images based on the first and second objective functions.;COPYRIGHT: (C)2010,JPO&INPIT
