In this study, compared to the treatment plan according to the electromagnetic and particle radiation of the radiation planning for prostate cancer. For this purpose, treatment plan of the electromagnetic, proton, and carbon radiation were established for prostate cancer patients using the MATRAD. Based on the IMRT treatment plan using electromagnetic radiation, the dose volume bar graph, the average dose of the maximum dose of PTV, the average dose of D95 and normal organs were measured, and the values of D5, dose homogeneity index and fitness index were compared. The maximum doses of PTV for electromagnetic radiation, proton, and carbon were 74.61, 73.65, and 73.54 Gy, the average doses were 66.69, 69.79, 69.89 Gy, and the D95 were 66.24, 67.29, and 67.32 Gy, respectively. In addition, the D5 was absorbed more in the rectum, although in normal organs the amount of protons and carbon were absorbed less than electromagnetic waves. Futhermore, In addition, the dose homogeneity index values were 7.5, 5.44, and 3.84, and the compatibility index was measured to be 0.76, 0.89, and 0.88, respectively, and carbon and electromagnetic radiation showed the lowest values at each index. In conclusion, treatment with proton and carbon with low dose homogeneity and low dose absorption in normal tissues is considered useful although the prescribed dose index for each prostate cancer radiation treatment plan was similar.

본 연구의 목적은 전자기파 방사선과 입자방사선에 따른 전립선암 방사선 치료계획을 비교하고자 한다. MATLAD를 이용하여 전자기파 방사선, 양성자, 카본을 이용하여 각각 전립선암 치료계획을 수립하였다. 전자기파 방사선을 이용한 IMRT 치료계획을 기준으로 선량체적히스토그램을 이용하여 분석하고, PTV 최대선량 평균선량, D95와 정상장기 평균 선량, D5를 비교하고, 선량균질지수와 처방선량지수를 비교하였다. 전자기파 방사선과 양성자, 카본의 PTV 최대선량 은 각각 74.61, 73.65, 73.54 Gy, 평균선량은 66.69, 69.79, 69.89 Gy, D95는 66.24, 67.29, 67.32 Gy 였다. 정상장기는 양성자와 카본이 전자기파보다 적은 선량이 흡수되었지만, 직장의 경우 D5가 높게 흡수되었다. 또한 선량균 질지수는 각각 7.5, 5.44, 3.84로 카본이 가장 적었으며, 처방선량지수는 0.76, 0.89, 0.88로 전자기파 방사선이 가장 적었다. 전립선암 방사선 치료계획 별 처방선량지수는 유사하였지만 선량균질지수가 낮고 정상조직에 선량흡수가 적은 양성자와 카본을 이용한 치료가 유용할 것으로 사료된다.
