Weasis: Darmowa i wolna przeglądarka DICOM

 
 
 

Bezpłatny/wolny program do przeglądania plików DICOM

 

Weasis to wszechstronny, przeglądarka DICOM o modułowej architekturze. Cieszy się dużą popularnością w placówkach medycznych, sieciach szpitalnych, badaniach klinicznych oraz wśród pacjentów

As free/libre and open source software (FLOSS), Weasis is cross-platform, multi-language, and supports flexible integration with PACS, RIS, HIS, or EHR systems. The viewer is compatible with Windows, Linux, and macOS across various processor architectures (see the available download packages).

Leveraging the OpenCV library, Weasis delivers high-performance and high-quality medical imaging renderings.

From version 4 onwards, Weasis features a responsive user interface aligned with operating system options, offering an enhanced experience on high-resolution screens.

Weasis has been designed to meet the evolving needs of clinical information systems in medical imaging. Its features focus on providing web-based access to radiological images, supporting a wide range of DICOM types, and offering multimedia capabilities.
