1. Avaliação, por meio de microtomografia computadorizada, da anatomia interna de incisivos inferiores / Internal anatomy of lower incisors evaluated by computerized microtomography
The knowledge of the root canal system (RCS) is of utmost importance to achieve success in the root canal treatment. The purpose of this study was to evaluate qualitative and quantitatively the RCS anatomy of mandibular incisors by means of microcomputed tomography. The image acquisition of 283 mandibular central incisors (MCI) and 329 mandibular lateral inc

2. Modelagem computacional de tomografia com feixe de prótons / Computational modeling of protons tomography
In the present work a preliminary research via computer simulations was made in order to elaborate a prior program for the first experimental pCT setup in Brazil. Proton therapy is a high precise form of a cancer treatment. Treatment planning nowadays is performed basing on X ray Computer Tomography data (CT), alternatively the same procedure could be perfor

4. Métodos híbridos para reconstrução tomográfica de imagens usando POCS e teoria da estimação / Hybrid methods for tomographic image reconstruction using POCs and estimation theory
Nesta tese é apresentado um novo método de reconstrução de imagens, por tomografia de transmissão, de projeções sujeitas a ruído na contagem de fótons. O método de reconstrução selecionado utiliza a técnica POCS (Projections Onto Convex Sets). A estimação das projeções originais a partir das observações ruidosas se dá por meio de quatro m

6. Neuropsicologia da doença Huntington : fatores preditivos em familiares geneticamente positivos e assintomaticos
Huntington s disease (HD) is an inherited neurodegenerative disorder of midlife onset that produces characteristic, progressive abnormal movements, dementia, and psychiatric and personality abnormalities. The gene responsible of the HD is localized in the short arm of chromosome 4. In early 1993 the search for the genetic defect ended with the discovery that
