SENSITIVITY IMPROVEMENT OF PIGMENT DOSIMETER BY CMR (COMMON MODE REJECTION) CONCEPT

摘要

PROBLEM TO BE SOLVED: To solve a problem of a radio chromic dosimeter wherein it has an excellent characteristic as a light element composition or a texture equivalent type, but there is an essential problem of low sensitivity due to the light element composition, and dramatic improvement measures of selectivity is demanded from various fields including medical treatment.;SOLUTION: An image recorded in a chromic film is scanned by a scanner in an IVR (interventional radiology), an optical CMR method is applied to groups of color components sensitive to radiation and color components insensitive to it in a personal computer, common noise remotely related to the radiation is reduced, and dose distribution is measured and obtained at high sensitivity and high accuracy.;COPYRIGHT: (C)2007,JPO&INPIT
