| 内容記述 | We developed a high radiation sensitive polymer gel by modifying the amounts of the gel components and the temperature for the gel preparation. We evaluated its relaxation time linearity against dose and compared the measured dose distribution with the calculated one. For the relaxation time-dose linearity, irradiations were carried out with a linear accelerator using 6MV photons and doses ranging from 0 - 5.0Gy. The relationship between dose and R2 value (reciprocal of T2 relaxation time) was measured and it had good linearity over a wide range (0.3 - 5Gy). The measured dose distributions were in good agreement with calculated ones. Since the present gel has higher sensitivity and it is synthesized more easily at lower cost than conventional polymer gels, we expect to see improved three-dimensional (3D) dosimetry using it. | |||||
