Otimização no processo de visualização e transferência de imagens diagnósticas em navegadores web: caso "Animati Pacs"

Abstract

Technology can improve the medical workflow and diagnostic procedures in clinics and hospitals. This work presents a set of architectural optimizations implemented in the existing Animati PACS web viewer system, improving the tool to make it available in desktop and mobile environments. The main contribution is the implementation of a new module that performs on-demand transference of medical images, enabling the viewer to run on devices with constrained resources. The viewer windowing functionality has also been improved through the implementation of a new and improved windowing module, which is able to run locally in the client’s browser or remotelly in the server. Another contribution is a literature review regarding medical diagnostics based on mobile imaging. The work also presents and discusses a validation performed to ensure the new additions made to the Animati PACS web viewer comply with the expected results of improving the existing system. The validation was created using a set of use cases based on real medical activities performed during digital diagnostics, all measured using metrics related to the accumulated volume of data transfered to and stored at the device.
