Resumo

Softwares tradicionais de avaliação de imagens médicas, como DICOM, possuem diversas ferramentas para mensuração de distância, área e volume. Nenhuma delas permite medir distâncias entre pontos em superfícies. O menor trajeto entre pontos possibilita o cálculo entre óstios de vasos, como no caso de aneurismas aórticos, e a avaliação dos vasos viscerais para planejamento cirúrgico. O desenvolvimento de um plugin para OsiriX para mensuração de distâncias em superfícies mostrou-se factível. A validação da ferramenta ainda se faz necessária.

Palavras-chave

validação de programas de computador; software.

Abstract

Traditional DICOM medical imaging software offers several tools for measuring distance, area and volume. None allow measurement of distances between points along surfaces. The shortest path between points makes it possible to calculate distances between the ostia of vessels, useful in cases of aortic aneurysms and for assessment of visceral vessels for surgical planning. Developing a plugin for OsiriX for measurement of distances along surfaces proved to be achievable. The tool still needs to be validated.

Keywords

software validation; software.
