1. Evaluation of ovarian structures using computerized microtomography
ABSTRACT Visualization and clear understanding of the ovarian structures are important in determining the stage of oestrus, helping to diagnose several pathologies and supporting advances in reproductive technologies. In this research, computerized microtomography (microCT) was used to explore and characterize the ovarian structure of seven mammalian species

2. Evaluation of simulated bone lesion in the head of the jaw by using multislice computed tomography / Avaliação de lesões ósseas simuladas na cabeça da mandíbula pela tomografia computadorizada multislice
There are limitations for image acquisition using conventional radiography of the temporomandibular joint (ATM) region. Computerized tomography (CT) scan is a better option due to its higher specificity and sensitivity for diagnosis, surgical planning and treatment of bone injuries. The purpose of this study is to evaluate simulated bone injuries of the head

3. Análise de imagens tomográficas da Ciência do Solo em ambiente de realidade virtual
This work presents a Virtual Reality environment dedicated to the analysis of tomographic images of Soil Science. Its architecture uses models proceeding from a volumetric (3-D) reconstruction algorithm, summed with several graphics processes of manipulation and visualization, in a way to provide immersion and interaction of the user with the virtual scene.

4. UM ESTUDO EXPERIMENTAL UTILIZADO EM TOMOGRAFIA DE RAIO-X COM MECANISMOS ASSOCIADOS A PRODUÇÃO DE AREIA EM POÇOS DE PETRÓLEO / AN EXPERIMENTAL STUDY USED IN X-RAY TOMOGRAPHY WITH MECHANISMS ASSOCIATED THE SAND PRODUCTION IN OIL WEELS
Frequently, during the production stages of an oil well, simultaneous production of solid particles originating from the surrounding rock mass occur, a process called sand production. Stress concentrations around of the well may cause loss of cohesion between grains, thus creating a region of loose granular matter susceptible for drag bye seepage forces. The

5. Multidetector computed tomography in the evaluation of the pulmonary embolism: use of the maximum intensity projection reconstructions / Tomografia computadorizada multidetectores na avaliação do tromboembolismo pulmonar: uso de reformatações em projeção de intensidade máxima
INTRODUCTION: Multidetector computed tomography (MDCT) has been making possible the increase of the sensibility in the detection of the pulmonary embolism (PE). It is observed, however, that there is a substantial increase in the number of images and, consequently, in the time of analysis for the radiologist. A possible solution to this problem is accomplish

8. Development and applications of three-dimensional gamma ray tomography system using ray casting volume rendering techniques
Computed Tomography (CT) has made possible visualization of physical structures in the interior of an object in their real relative spatial position and orientation. Another important contribution of CT is to greatly improve abilities to distinguish regions with different gamma ray transmittance and to separate over-lying structures. The mathematical problem

9. EXPERIMENTAL STUDY OF MECHANISMS OF SAND PRODUCTION USING X-RAY COMPUTERIZED TOMOGRAPHY / ESTUDO EXPERIMENTAL DOS MECANISMOS DE PRODUÇÃO DE AREIA EMPREGANDO TOMOGRAFIA COMPUTADORIZADA DE RAIOS-X
During productive phase of the well, manytimes there is simultaneous production of the solid particles detached from matrix of the reservoir rock. This phenomenon receive the name of the sand production. In this case stress and flow conditions around of the well are fundamental factors for deflagration of the process. Stress concentration in the wall of the

11. Determinação de porosidade e saturações de fluidos atraves da tomografia computadorizada de raios-x
X-Ray Computerized Tomography (Cf) is a non destructive analysis technique that allows the visualization of the internal structure of an object. Its applications in the petroleum industry include, among others, reservoir rock characterization and multiphase fluid flow studies in pomus media. This work presents the principIes of this imaging technique and the

12. Percutaneous CT-Guided Treatment of Lumbar Facet Joint Synovial Cysts
Symptomatic intraspinal lumbar facet joint synovial cysts can be managed both conservatively and surgically. Diagnosis of the lumbar facet joint cyst is made through cross-sectional imaging of the spine, either by computerized tomography (CT) scan, myelography, or most commonly magnetic resonance imaging. Conservative treatment by facet joint injection can b
