Abstract
High dose rate interstitial brachytherapy (hdr ibt) is a widely used and advanced technique to treat liver tumours by maximising the prescribed dose and sparing the adjacent organ at risk (oar) from unwanted radiation. The main objective of this retrospective study was to evaluate the dosimetry parameters of the oar especially central liver structure (cls), right chest wall (rcw) and right diaphragm (rd) using hdr ibt and iridium-192 (ir-192) source. This study used computed tomography (ct) data from the oncentra treatment planning system (tps) to retrospectively analyse the dose distribution in 89 hdr ibt treatment cases of 55 patients. These data were used to statistically analyse the relationship between the dosimetric variables of oar doses through single and multiple hdr ibt fractionations at prescribed dose of 15 gy, 20 gy and 25 gy.
