| Summary: | 碩士 === 中臺科技大學 === 放射科學研究所 === 98 === Percutaneous Coronary Intervention in the clinic for more complex coronary artery disease patients, often takes a long time for diagnosis and treatment, together with the whole process must by X-ray machine was able to complete secondary perspective, so that patients for long-term X-ray radiation exposure can cause harm, are often ignored by doctors and patients. In this study,the TLD distribution in the 30, 50 and 70 kg PMMA phantom replace the patients underwent interventional cardiac catheterization X-ray irradiation, respectively, exposure 70,140,210 and 280 seconds. In the diagnosis process of
the received value of the effective dose and BMI, exposure time and skin dose using Mathematical software to do further investigation. The derived effective doses for 30kg phantom were 316.12±17.78 μSv 、443.92±21.07 μSv 、
668.68±25.86 μSv and 1028.79±32.07 μSv whereas the effective doses for 50kg phantom were 475.97±21.82μSv、806.24±28.39μSv、1077.18±32.82μSv and 1693.87±41.16μSv, whereas the effective doses for 70kg phantom were
312.53±17.68μSv、845.52±29.08μSv、904.98±30.08μSv and 1648.01±40.60μSv, respectively under 70s, 140s, 210s, and 280s exposure times.
