Medical imaging environment : a multi-agent system for a computer clustering ba...
Alves, Victor; Marreiros, Filipe; Nelas, Luís; Heymer, Mourvlise; Neves, JoséThis paper presents a solution to minimize a problem that normally arises from the huge amount of images that a radiologist usually has to interpret. A multi-agent system that implements a multi-display for medical imaging based on computer clustering of normal personal computers is therefore described, as well as the multi-agent architecture that caters for the system evolution. An evaluation study was perform...
Análise e interpretação de imagem médica com o apoio de agentes de software
Marreiros, FilipeA evolução dos equipamentos utilizados na radiologia, desde as unidades de Ressonância Magnética (RM) de 3-tesla e sistemas de Tomografia Computorizada (TC) de 64 cortes em simultâneo até à ultima geração de tecnologias híbridas como a Tomografia por Emissão de Positrões (TEP)/TC está rapidamente a produzir volumes de imagens que ameaçam superar a capacidade de interpretação dos radiologistas. Os procedimentos ...
A multi-agent based medical image multi-display visualization system
Alves, Victor; Marreiros, Filipe; Nelas, LuísThe evolution of equipments used in the medical imaging practice, from 3-tesla Magnetic Resonance (MR) units and 64-slice Computer Tomography (CT) systems to the latest generation of hybrid Positron Emission Tomography (PET)/CT technologies is fast producing a volume of images that threatens to overload the capacity of the interpreting radiologists. On the other hand multi-agents systems are being used in a wid...
Calculating the stereo pairs of a Mirror-Based Augmented Reality System
Marreiros, Filipe; Marcos, Adérito13º Encontro Portuguûes de Computação Gráfica, Vila Real, 12-14 de Outubro de 2005 ; This paper describes a solution for the calculation of the correct stereo pairs of a Mirror-Based Augmented Reality System (MBARS). To achieve augmentation half-silvered mirrors are applied due to their dual reflection characteristic that allow simultaneous seeing-through of real objects and the viewing of reflected virtual on...
Collaborative multimodal authoring of virtual worlds
Sá, Vítor; Marcos, Adérito; Marreiros, FilipeThis work aims the creation of virtual worlds by working teams with resource to advanced interaction techniques, such as speech commands and gestures, as well as the resource to portable devices. The physical characteristics of virtual reality environments lead us to a different kind of user interfaces. However, we found some usefulness on the classic WIMP paradigm, which we also apply by using a PDA, in order ...

Web-based medical teaching using a multi-agent system
Alves, Victor; Neves, José; Nelas, Luís; Marreiros, FilipeWeb-based teaching via Intelligent Tutoring Systems (ITSs) is considered as one of the most successful enterprises in artificial intelligence. Indeed, there is a long list of ITSs that have been tested on humans and have proven to facilitate learning, among which we may find the well-tested and known tutors of algebra, geometry, and computer languages. These ITSs use a variety of computational paradigms, as pro...
