Phantom conception for development of planar scintigraphic image restoration procedures

The instrumentation and physiological patient factors bound to the patient in-vivo complicate the treatment of the images during a medical examination. Thus, they can contribute to the generation of artifacts in the resulting images. The artifacts degrade the quality of the images and can lead, in certain cases, to a bad diagnosis. For this reason, the appeal to the use of the simulation techniques allows to evaluate and improve the devices of acquisition and image processing. The models (called phantoms) are important tools to simulate human anatomy and physiology and to allow the evaluation of acquisition methods and image analysis. Thereby, the simulation offers a way of great importance to evaluate and improve medical techniques of acquisition devices, treatment and the reconstruction of images in-vitro.
