MEASUREMENT
Quantify geometry
Measure distances, angles, and paths directly in 3D. Export measurements as CSV for further analysis.
Why spatial
Volumetric medical imaging has always been three-dimensional. Now the interaction is too.
Volume tools
More ways to work with a volume.
Measure, segment, and register in 3D on Apple Vision Pro, iPad, and iPhone.
SEGMENTATION
Isolate regions
Separate regions of interest and refine their boundaries. Export labeled volumes, 3D surfaces, and statistics for further study.
REGISTRATION
Align volumes
Bring two scans into alignment and compare them in a fused view. Save the alignment for your workflow.
The same tools are available on all three platforms. Tools are free to try on sample images; in-app purchases unlock them for your own cases.
COLLABORATION
Share your workspace
Explore the same case together with SharePlay. Invite others to view or edit, and choose whether to keep the session's annotations.
IMAGING TOOLS
Explore image details
Follow curved structures, view thicker slices, and inspect image intensity. Adjust image contrast and PET colors to explore the details.
BATCH TOOLS
Automate workflows
Work through planned scan pairs and process saved alignments in batches. Export results and step-by-step records for repeatable research workflows.
The core interaction
Two ways to slice. Across your 3D tools.
Use the same spatial interaction as you measure, segment, and register. Follow your viewpoint, or position the plane by hand.
SLICE MODE / AUTOMATIC
Tracked auto-slicing
The oblique plane follows your viewpoint — head-tracked on Apple Vision Pro, device-tracked on iPad and iPhone. Move yourself, and the cut moves through the anatomy.
SLICE MODE / MANUAL
Fixed manual-slicing
Lock the plane in place and drag it through the volume by hand — for slow, deliberate positioning and repeatable views.
Try both interaction modes for free with the sample images.

Measurement validation
Measured against
known geometry.
How do spatial measurements compare with known dimensions? A study using VoxelVision 1.2.1 tested distances, angles, paths, and perimeters on reference objects, with 570 blinded measurements across 100 volumes.
This study evaluated measurement with a single trained operator on reference objects, not segmentation, registration, or performance on clinical anatomy. VoxelVision is for education, research, and workflow exploration, not clinical diagnosis or treatment.
Explore measurement results and study methods
The study characterized pose-tracked double-oblique multiplanar reformation across three types of reference phantom, on head-mounted and handheld platforms.
Three-tier validity gradient
Cue realism increases →
Across 570 blinded measurements on 100 single-target volumes, the synthetic-phantom results were statistically equivalent across voxel spacing, platform, and session re-entry. Characterized with a single trained operator on phantoms with known reference geometry; generalization across independent operators and extrapolation to clinical anatomy define the boundary for subsequent study. VoxelVision is not a certified medical device.
