cardio

cardio is a simple web-based viewer for 3D and 4D ('cine') medical imaging data, built primarily on trame, vtk, and itk. cardio can render sequences of mesh files (e.g., \*.obj files), segmentation files (e.g., \*nii.gz files with discrete labels) and volume renderings of grayscale images (e.g., \*.nii.gz files with continuous values). cardio is launched from the commandline and may be configured via commandline arguments, a static TOML configuration file, or a combination of the two.
