BERNAL-ROMERO, Óscar Humberto; MOLINA-PRADO, Martha Lucía  e  ARIAS-HERNANDEZ, Néstor Alonso. Simulation environment 3D and calculation to point, in radiotherapy using diagnostic image processing. Iteckne [online]. 2014, vol.11, n.2, pp.129-139. ISSN 1692-1798.

The main goal of radiation therapy is to provide a high dose of ionizing radiation to the volume defined as injury or target, and reduce the dose to organs or tissues that are close to its anatomy, without subdosificar the treatment area. Due to this, the three-dimensional visualization of the treatment area is of great importance in subsequent simulation and treatment planning. This is a of the importance of using medical diagnostic images in this process.The information visual of medical diagnostic images done in studies carcinogenic ill patients are obtained with diagnostic equipment (for this project will focus on Computed Tomography CT and NMR Nuclear Magnetic Resonance), allow the acquisition of data that has great importance for treatment. By processing this group of images, the volume reconstruction is obtained (3D visualization) from tumor areas of each tissue or areas of interest, through of processing digital of images. The zones reconstruction 3D of interest permitted determining simulation parameters for teletherapy treatments as: the delimitation of area to be treated, reducing surrounding areas or organs. Additionally, it obtained the information for focusing of the treatment beam, for determining field sizes, angles of the couch, gantry and collimator. With these data and calibration data processing equipment (Accelerator), the treatment time or calculation point is determined, which allow in the Radiotherapy improve treatment and its results.
