1. 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

2. Adoption and asessment of innovative health technologies within the Brazilian health care system: a case study in cardiology / Incorporação e avaliação de novas tecnologias no sistema de serviços de saúde brasileiro: estudo de caso na área de cardiologia
Introdução: Amplo debate tem associado a incorporação de novas tecnologias para a saúde com os custos crescentes dos sistemas de saúde. Face à dúvidas "se as novas tecnologias são parte do problema, parte da solução ou as duas coisas" relativamente à saúde da população e do sistema de saúde, este estudo de caso analisa a incorporação de tr�

3. Dose spread functions in computed tomography: A Monte Carlo study
Purpose: Current CT dosimetry employing CTDI methodology has come under fire in recent years, partially in response to the increasing width of collimated x-ray fields in modern CT scanners. This study was conducted to provide a better understanding of the radiation dose distributions in CT.

4. Design and characterization of a spatially distributed multibeam field emission x-ray source for stationary digital breast tomosynthesis
Digital breast tomosynthesis (DBT) is a limited angle computed tomography technique that can distinguish tumors from its overlying breast tissues and has potentials for detection of cancers at a smaller size and earlier stage. Current prototype DBT scanners are based on the regular full-field digital mammography systems and require partial isocentric motion
