- A prototipagem rápida na modelação de patologiasPublication . Queijo, Luis; Rocha, João; Pereira, Paulo Miguel; Barreira, Luísa; San Juan, Manuel; Barbosa, Tiago M.A utilização da prototipagem rápida tem, cada vez mais, vindo a revelar-se como uma ferramenta de extremo valor no apoio à actividade médica. Partindo de imagens médicas bidimensionais provenientes de Tomografia Computorizada (TC) ou Ressonância Magnética (MRI) é possível a obtenção de modelos tridimensionais. Os modelos produzidos por prototipagem rápida têm utilidade quer em ambiente educacional, quer em ambiente médico- cirúrgico. Podem facilitar o diagnóstico de determinadas patologias, a elaboração de procedimentos cirúrgicos complexos, o fabrico de próteses, o fabrico de instrumentos médicos bem como a visualização de estruturas anatómicas em ambiente educacional.
- Surgical training and post-surgery evaluation using rapid prototyped biomodelsPublication . Queijo, Luis; Rocha, João; Pereira, Paulo Miguel; San Juan, ManuelThe biomedical use of rapid prototyping technologies (RP) had great developments in the last years, especially as supportive tools for tissue growth, direct or supportive technology for implant fabrication or as tool for personalized biomodels production applied to studies, this research will focus on this last type of usage in continuation of previous work developed with RP as an aid of surgery procedures. Biomodels can play an important role as a complementary diagnostic method to medical staff (Queijo et al., 2010). The usage of RP technologies for biomodels production, in Lytic Spondylolisthesis surgical training and as a tool for post-surgery evaluation, is presented in this paper.
- A surgical training model manufacture using rapid prototyping technologyPublication . Queijo, Luis; Rocha, João; Barreira, Luísa; Barbosa, Tiago M.; Pereira, Paulo Miguel; San Juan, ManuelThe use of rapid prototyping has increasingly begun to reveal itself as a tool of great value in supporting medical activity. From two-dimensional medical images from computed tomography (CT) or magnetic resonance imaging (MRI) it is possible to obtain three-dimensional models. The models produced by rapid prototyping technologies are useful both in educational and medical-surgical environments. It can simplify the diagnosis of certain diseases, the development of complex surgical procedures, the prostheses and medical devices manufacture and the visualization of anatomical structures in educational environment.
