METHOD AND APPARATUS FOR FORMING IMAGE INDICATING CHANGE IN TEMPERATURE IN SPECIMEN

PROBLEM TO BE SOLVED: To improve the accuracy of temperature measurement of tissue in an organism. SOLUTION: An NMR image showing thermal changes in tissue under treatment is made using a gradient recalled double echo pulse sequence. A reference phase image is generated 118 and 107 using a short ech...

Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the accuracy of temperature measurement of tissue in an organism. SOLUTION: An NMR image showing thermal changes in tissue under treatment is made using a gradient recalled double echo pulse sequence. A reference phase image is generated 118 and 107 using a short echo time TE1 and a measurement phase image is generated 118 and 107 using a longer echo time TE2 . Using phase difference information in a pixel corresponding to those two phase images, a temperature map is generated during treatment.
