THREE-DIMENSIONAL TEMPERATURE-MEASURING METHOD USING MRI APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional temp.-measuring method which measures three-dimensional temp. distribution in a subject by using an MRI apparatus and displays it as a three-dimensional image. SOLUTION: Three-dimensional MR imaging sequence contg. three-dimensional temp. distribution information is performed (S101) and three-dimensional phase distribution is calculated from three-dimensional complex MR image obtd. (S102) and then, three-dimensional phase unwrapping processing is performed (S103) and three-dimensional temp. distribution is calculated from three-dimensional phase distribution after unwrapping processing (S104). To this result of calculation, vol. rendering processing is performed to prepare three-dimensional temp. image and it is displayed (S105).
