Radiotherapy Support Tools, the Brazilian Project: SIPRAD

The radiotherapy planning process (teletherapy) is initially performed by the acquisition of Computed Tomography images of the areas of interest to guide a series of health professionals in the work of vector design of regions of interest for protection (risk organs) and radiation (tumors). All these steps are performed using computational tools that extrapolate measurements and scales in the treatment plan. The efficiency of the treatment depends on the recreation of the patient's positioning on the linear accelerator stretcher with the previously acquired tomography images. For this, in this article, we present three modules of the SIPRAD (Information Systems for Radiation Therapy Planning) project. With the name of Radiotherapy Portal it is able to perform a fusion of planar images of the target region, made on the day of treatment, with the digital recreation (DDR - Digital Reconstructed Radiographs) of this radiograph generated from the Tomography of treatment planning, aiming to improve the reproducibility of the positioning that the radiation dose delivered during all the radiotherapy treatment. The second module named by LYRIA PACS RT provides a client/server architecture for storing, distributing and displaying images from any systems using the DICOM RT Struct, Image, Plan and Dose modes. The third module called Contouring is responsible for the training of new radiotherapists.
