Simple DICOM Viewer

Simple DICOM Viewer is an advanced application for importing and visualizing compatible DICOM CT and MR image series as interactive three-dimensional volumes on iPad and Apple Vision Pro.

Designed for education, research, software evaluation, engineering workflows, and professional image review, the app combines an efficient integer-voxel data pipeline with GPU-accelerated volume rendering and native controls.
App offers
-GPU-accelerated 3D DICOM volume visualization
• Direct volume rendering, MIP, and isosurface modes
• Bone, soft-tissue, lung, vessel, skin, grayscale, and MR presets
• Interactive window and level adjustment
• Transfer-function editing
• Sagittal, coronal, and axial clipping controls
• Six-sided crop controls
• Adaptive memory and rendering-quality management
• Integer-voxel storage and empty-border reduction
• Immersive Apple Vision Pro presentation
• Spatial move, rotate, and scale controls
• Local user-selected file processing
• Integrated consent, privacy, terms, help, and license informationTHREE-DIMENSIONAL VOLUME VISUALIZATION
Import a compatible DICOM series and explore the dataset as a 3D volume. Adjust the view interactively, rotate the dataset, change scale, and focus on regions of interest without creating separate diagnostic 2D viewing windows.

RENDERING MODES
• Direct volume rendering for layered anatomical visualization
• Maximum intensity projection for high-intensity structures
• Isosurface visualization using an adjustable threshold
• Adaptive quality settings for balancing visual detail and performance

PRESETS AND TRANSFER FUNCTIONS
Choose presets designed for common visualization tasks, including bone, soft tissue, lung, vessels, skin, grayscale, and MR-style views. Refine color and opacity using the transfer-function controls.

WINDOW AND LEVEL
Window and level adjustments are performed in the GPU rendering pipeline, allowing rapid visualization changes without rebuilding the complete source volume.

CLIPPING AND CROPPING
Use sagittal, coronal, and axial clipping controls to inspect internal anatomy. Apply crop bounds and clipping inversion to isolate the area you want to study.

APPLE VISION PRO
Open the volume in immersive space and place it in front of you as a spatial object. Use supported gestures to move, rotate, and scale the volume while retaining the selected rendering controls.

MEMORY-CONSCIOUS LOADING
The application uses integer voxel values, adaptive loading, empty-border cropping, and quality limits to reduce memory pressure when working with larger studies. Rendering performance depends on dataset dimensions, transfer syntax, device resources, and selected quality.

PRIVACY-FIRST WORKFLOW
DICOM files are selected by the user and processed locally by the application whenever possible. The app does not require an account and does not automatically upload medical images to Orthopractis servers.

SUPPORTED CONTENT AND LIMITATIONS
Compatibility depends on the DICOM transfer syntax, image organization, photometric interpretation, pixel format, and study structure. Some compressed or proprietary DICOM datasets may require an optional compatible decoder and may not load in the current release.

INTENDED USE
Simple DICOM Viewer is intended for visualization, education, research, demonstration, engineering evaluation, and software testing. It is not intended to replace qualified medical judgment, a certified radiology workstation, or a regulated diagnostic medical device. Do not use the app as the sole basis for diagnosis, treatment, surgical planning, or emergency decisions.
