Touch3D Scan

Touch3D Scan is an Apple Vision Pro workspace for viewing compatible CT, MRI, DICOM, scientific-volume, mesh, and USD-family files in windows and mixed immersive space. VIEW THE DATA - Sagittal, coronal, and axial source views - Single-slice, tri-planar, thick-slab, peel, and informative full-stack views - Cine playback and exact First, Last, -10, -1, +1, and +10 navigation - Window/level, opacity, transfer-function, crop, clipping, lighting, and rendering controls - Composite, MIP, MinIP, and ISO volume-rendering modes RESEARCH ALIGNMENT WORKFLOWS Touch3D Scan includes guided research and engineering tools for estimating a static rigid relationship between a scan model and a physical reference surface: 1. Four corresponding points Select four named scan-side points and collect the corresponding physical-space points. The app calculates a software alignment estimate, identifies inconsistent pairs, and requires separate holdout verification. 2. Four points plus surface samples Start from the four-point estimate, then collect separated surface samples. The app reports software residuals, coverage, correspondence support, and drift from the initial estimate. 3. Reviewed external skin manifest Import an independently reviewed, study-specific external-surface manifest, then complete the same physical point and surface workflow. No automatic SAM service or automatic patient-study upload is included in this build. INPUT HARDWARE The primary input method is Apple Vision Pro's built-in Hand Tracking. A compatible Logitech Muse may optionally be used as a general-purpose spatial input accessory for point selection, surface tracing, and Undo. Muse is not required. Touch3D Scan does not connect directly to CT/MRI scanners or to regulated medical hardware. LOCAL-FIRST PROCESSING No Orthopractis account is required. The submitted build does not include advertising, behavioral tracking, developer-operated analytics, or automatic upload of selected studies to Orthopractis. User-selected files are processed locally. User-initiated exports and independently selected external services are controlled by the operator and are subject to the destination service's terms. HARDWARE AND REGULATORY STATUS Touch3D Scan uses Apple Vision Pro as a spatial computer and may use an optional general-purpose spatial input accessory. It does not connect to or control regulated medical hardware. No medical-device or medical-hardware regulatory clearance is claimed in any jurisdiction. IMPORTANT MEDICAL DISCLAIMER Touch3D Scan is intended only for visualization, education, research, demonstration, engineering evaluation, and software testing. It is not intended for diagnosis, treatment, surgical navigation, emergency care, or medical decision-making. Do not use this app as the sole basis for any medical decision. Seek advice from an appropriately qualified doctor in addition to using this app and before making any medical decision. Use validated and appropriately authorized systems for clinical care. Registration is static and must be repeated after relevant movement of the person, anatomy, bed, support, headset, or tracking coordinate system.
