From loading images through 3D and quantitative analysis. The main features of GRAPHY-Next.
2D viewer
Stack display, window/level presets, cine, and intensity calibration (HU and SUV managed together).
MPR / slab MIP
Reslicing in three orthogonal planes, with gantry tilt correction, plus MIP, MinIP and AvgIP slab projection in 2D, MPR and 3D.
Slicer / curved MPR
Oblique planes at any angle and three kinds of curved planar reformation along a centreline.
3D (VTK.js)
Volume and surface rendering, cinematic rendering, 3D measurement and clipping.
ROI / masks
Draw and manage 2D regions of interest, paint masks, and convert between ROIs and meshes.
Radiomics
Texture analysis through RadiomicsJ, with a settings interface.
PET / CT fusion
Fusion overlays and SUV calibration (body weight and others).
DICOM networking
Storage, DIMSE, DICOMweb and REST, query/retrieve, and remote send.
