Abstract

Treatment Planning System (TPS) are used to determine the dosedistribution to be received before the irradiation in patients. To see how much radiation dose to be received on the target volume and surrounding critical organs that are required isodose curve. 2D isodose curves correction on non-homogeneous tissues done because in fact the human body not only in the form of soft tissue, but there are also other tissues such as bone tissue or lung. Isodose curve correction have been made using Tissue Air Ratio (TAR) method with Matlab software on a wide field of 10 x 10 cm2. Correction factor is obtained by comparing the effective depth of the TAR with TAR at each depth. Correction factor multiplied by the curve isodose for homogeneous phantom have been obtained from Percentage Depth Dose (PDD) and dose profiles. Corrected isodose curves obtained for nonhomogeneous phantom. Higher the density value on nonhomogeneous phantom, the attenuation will increase and produce the lower dose. Keywords: Treatment Planning System (TPS), 2D Isodose curve, Tissue Air Ratio (TAR), Correction factor, nonhomogeneous tissue, attenuation

Abstract

Research has been done to make isodose curve of electron beam with the energy of 5 MeV. Isodosis curve performed using PDD curves and dose on broad Profile 10x10 cm2 field; 15x15 cm2; 20x20 cm2; 25x25 cm2, with a depth of 0.5 cm; 1.0 cm; 1.5 cm; 2.0 cm; 2.5 cm. The purpose of this study was to obtain 2D isodose curve shape can be applied to TPS in Radioteraphy.The method which was used to form the isodose curve using PDD curves and dose profiles was done by equalizing the data at each depth using interpolation techniques at intervals of 0.25 cm and normalized to a value of 1, and calculatd the dose at each pixel using the weighting technique that formed isodosis curve with the distribution each depth and broad field. The results show that the PDD curve formed using the interpolation does not affect the magnitude of the dose at different field wide, profile shaped dose showed a dose level at each different depth and normalized to a value of 1 to show the dose at the surface, the isodose curve formation can be applied to compare the isodose curve formed by TPS in Radiotherapy. Keywords: Radiotherapy, Treatment Planning System (TPS), isodose curve, Percentage Depth Dose (PDD), Profile dose
