| Research Abstract |
(1) Three types of sheet films which have suitable sensitivity for the measurement of relative high dose level causative of acute radiation skin injury were selected for evaluation
(2) Comparison studies using a phantom with other radiation measuring methods proved the measurement by any type of sheet films to be accurate. for the measurement of skin dose to patient : during IVR, procedures
(3) Cinical comparison studies revealed superiority in stability and accuracy of sheet film measurement to area monitor or skin dose monitor (SDM) measurements. Among sheet films, reflective self developing type of sheet film was the most stable and simple to use in comparison with transparent sheet Elms which needed the development procedure and calibration in each measurement
(4) We developed a computer system for analysing the obtained data to get accurate two dimensional accumulated skin dose of patients
(5) We developed a mapping system for the accumulated skin dose to patients in repeated procedures with reasonable accuracy
