 Abstract
This study tries to evaluate the usefulness CSI treatment. Compare the standard technique and simple technique, using the volume region of a high dose of Field joints (hot spot) or low dose regions (cold Spot). In patients who agreed to this study, obtain CT image using CT simulator skull to pelvis region. Standard Technique were performed on the movement of the joint radiation field range and simple technique has set a treatment plan to secure the radiation field range and analyzed treatment planning. Under analysis standard technique occurred the area of the high dose(Hot Spot) for the area overlapping the field and simple technique showing a uniform doses. CI indices of standard technique and simple technique was 1.6~3, 1.6~1.87, CN indices was 0.32~0.53, 0.46~0.51 and HI indices was 0.11~0.33, 0.2~0.26. Therefore, adjacent to part of the dose distribution junction more equally than simple technique compared to the Standard Technique. Compare the dose distribution patterns using CI, CN, HI indices, showed a uniform dose distribution in the simple technique. so, simple technique was determined appropriate treatment the CSI.
