1. Análise da densidade óssea e da atenuação do feixe de raios X nos tecidos moles, em mandíbula de coelhos submetidos à lasertarapia, durante a distração osteogênica
INTRODUCTION: Cone-beam computed tomography (CBTC) provides detailed information about the amount and quality of new bone formed during distraction osteogenesis (DO). The density of the lengthened bone is measured based on different levels of gray found in the images. The use of CBTC therefore allows to perform a quantitative analysis of bone density and, th

2. Mapeamento tomográfico do processo alveolar para instalação de mini parafusos ortodônticos.
Este estudo determinou sítios anatômicos inter-radiculares mais seguros para instalação de mini parafusos ortodônticos. Foram analisadas 20 hemi-arcadas da maxila e 20 hemi arcadas da mandíbula, nas regiões inter-radiculares entre canino e pré-molar (CP), primeiro e segundo pré-molares (PP), segundo pré-molares e primeiro molares (PM) e primeiro e

3. Thermal neutron computed tomography at the Argonauta Reactor
Since 1985 the Argonauta Reactor at the Instituto de Engenharia Nuclear - IEN/CNEN has been used as a source of thermal neutrons to acquire transmission-generated radiographic images. From that time until the end of the last century, some Universities and Research Institutions have as well used the irradiation facilities of this reactor for that purpose and

4. Classificação radiográfica da dificuldade cirúrgica dos terceiros molares inferiores inclusos / Radiographic classification of surgical difficulty of impacted mandibular third molars
The classifications of third lower molars observed in the literature commonly valorize the angulation of the teeth to orient the surgical technic. However, there is a lack of articles talking about previous establishment of surgical difficulties. The aim of the present study was to elaborate a radiographic classification related to the surgical difficulties

5. Development of the technology of nuclear magnetic resonance tomography (ToRM) / Desenvolvimento da tecnologia de tomografia por ressonância magnética nuclear
We describe in this work the development of hardware and software necessary to implement the Magnetic Resonance Imaging (MRI) techniques. Our major subjects were the construction of an acquisition and control system which allowed the operation of a pulsed Fourier NMR spectrometer as a NMR Tomograph; further we oriented the developing of a NMR spectrometer wh

6. In vivo quantification of localized neuronal activation and inhibition in the rat brain using a dedicated high temporal-resolution β+-sensitive microprobe
Understanding brain disorders, the neural processes implicated in cognitive functions and their alterations in neurodegenerative pathologies, or testing new therapies for these diseases would benefit greatly from combined use of an increasing number of rodent models and neuroimaging methods specifically adapted to the rodent brain. Besides magnetic resonance
