Uma solução para renderização remota de imagens médicas tridimensionais: análise de desempenho

Abstract

This paper proposes and analyzes a solution for remote rendering of three-dimensional medical images (3D). In this solution, the entire process of volume rendering is performed by a server (or server cluster) and only the resulting picture is sent to the customer, yet allowing it to perform operations such as rotation, pan and zoom. To perform the analysis of performance, three different execution scenarios were defined. In the first scenario, the process was performed by a server with graphics hardware (GPU). In the second, we used a server without GPU, but with high processing power in parallel, having 48 cores (processing units). The third scenario was used to simulate the default behavior of most medical visualization applications, where the entire rendering process was performed locally on a computer. With the results obtained, it has been shown that the proposed solution solved satisfactorily two of the main problems of three-dimensional visualization of medical examinations, being they: the time spent for the transfer of DICOM files and the computational power required to perform the rendering process. The architecture of solution allows less powerful computers and mobile devices (tablets and mobile phones) being used for visualization of tomography and magnetic resonance images
