چکیده

We introduce a fast and well-structured package for constructing voxel-based computational phantoms as MCNP(X) input file based on CT DICOM images. Our program which has been implemented under a graphic user inter-face provides several basic image processing tools for manipulating images. The MCNP materials are interpreted from the CT numbers of DICOM images. Two modes of phantom creation have been provided using individual cells and lattice. In the former, the program uses a fast merging algorithm for reducing the number of cells and in the latter, an optimized approach has been followed. This software has strong potential in applications in radiologic, dosimetry and therapeutic MCNPbased Monte Carlo studies. Keywords— anthropomorphic phantoms, voxel-based models, Monte Carlo simulation, MCNP.

Accuracy Evaluation of Oncentraâ„¢ TPS in HDR Brachytherapy of Nasopharynx Cancer Using EGSnrc Monte Carlo Code

Background: HDR brachytherapy is one of the commonest methods of nasopharyngeal cancer treatment. In this method, depending on how advanced one tumor is, 2 to 6 Gy dose as intracavitary brachytherapy is prescribed. Due to high dose rate and tumor location, accuracy evaluation of treatment planning system (TPS) is particularly important. Common methods used in TPS dosimetry are based on computat...
