Abstract

Research on verification of the radiation dose of a 6 MV and 10 MV photon beam on Clinac CX type Linear Accelerator (LINAC) has been conducted at Andalas University Hospital. This research aims to determine the radiation beam correction factor to obtain measured dose values and obtain the value of absorbed dose verification value based on the Technical Report Series (TRS) No. 398 International Atomic Energy Agency (IAEA). The research began with planning on the CT-simulator. Furthermore, the measurement of radiation dose on the phantom slab using a Clinac CX type LINAC therapy aircraft with a farmer chamber ionization detector, target depth variations of 1,5 cm, 2,5 cm, and 10 cm, and field area variations of (6×6) cm2, (10×10) cm2, (15×15) cm2, (8×13,3) cm2, dan (9×11,5) cm2. Furthermore, radiation dose verification is carried out by comparing the radiation dose at the TPS to the dose measured using the farmer chamber ionization detector. The absorbed dose value obtained based on the planning dose at the TPS increased at maximum depth and decreased as the depth of the irradiation field increased. Verification of the radiation dose that meets the tolerance limit is below 5%. The appropriate measurement results were obtained at a maximum depth (Dmax) of 2,5 cm, except at depths of 1,5 cm and 10 cm.

Abstract

Analysis of breast cancer radiation dose distribution using bolus density in radiotherapy planning of the Three-Dimensional Conformal Radiotherapy (3DCRT) technique has been conducted. This research aims to analyze radiation dose distribution in breast cancer patients using bolus density in radiotherapy planning of the 3DCRT technique. Five images of breast cancer patients were processed using TPS Eclipse software. The bolus density values used were a mixture of beeswax and petroleum jelly, playdough, silicone rubber, and 3D Polylactic Acid. CI and HI values were calculated based on the International Commission on Radiation Units and Measures (ICRU) Reports 62 and 83. Radiation dose in OAR was verified based on the Quantitative Analysis of Normal Tissue Effect in the Clinic (QUANTEC) standard. The results showed that all four bolus densities can be used in breast cancer patients, with CI values the CI value ranges from 0.93 to 0.98 by ICRU Report 62 standards and HI values close to ICRU Report 83 standards. In cardiac OAR, one patient exceeded the QUANTEC standard, while for lung OAR, all patients were below the QUANTEC standard. Using bolus density provides optimal radiation dose distribution on breast cancer targets.
