Starviewer is cross-platform medical imaging software fully compliant with the DICOM standard for image communication and image file formats.
It integrates state-of-the-art image visualization and assessment tools needed in medical image diagnosis, but also advanced reconstruction techniques, 3D navigation tools and image fusion support. Its modular design allows the addition of new functional modules and it may be integrated with any healthcare information system (PACS/HIS/RIS).
This is free and open source software.
Features include:
- 2D Viewer allows the visualization and manipulation of images of any DICOM modality. It includes tools to manipulate images (pan, zoom, rotate, flip, invert), to compute measures (distances, angles, 2D ROIs, TA-GT), and advanced reconstruction techniques: orthogonal reconstructions, thick slab (MIP), reference lines, 3D-cursor, and spatial image synchronization along series. It also includes support for PET-CT and SPECT-CT image fusion.
- Support for PET-CT and SPECT-CT image fusion in any orthogonal reconstruction. It has support for SUV calculation on PET and different CLUTs are offered. The contribution of each volume to the fusion can be easily modified and custom thick slab can be applied to any volume simultaneously.
- Volumetric data can be visualized in 3D using the 3D Viewer. There are implemented different rendering methods such as Ray Casting, MIP or Iso Surface. The user can define the region of the volume aimed to visualize. It includes predefined CLUTs as well as a complete editor to define new styles.
