Optimizing Clinical Review with Medical Image Viewer (MIView)

MIView Tutorial: Getting Started with the Medical Image Viewer

This tutorial walks you through setting up MIView, loading studies, navigating images, using key tools, and configuring settings for efficient diagnostic review.

1. Installation and first launch

1. Download the MIView installer for your operating system from the official distribution (Windows, macOS, or Linux).
2. Run the installer and follow on-screen prompts; accept default locations unless you need a custom path.
3. On first launch, grant any required permissions (file access, network) so MIView can open DICOM files and, if applicable, connect to PACS.

2. Loading studies

1. Open local files: Use File → Open or drag-and-drop DICOM folders/ZIPs into the main window. MIView will parse the DICOMDIR or individual files and group series by study.
2. Import from PACS: Configure a DICOM node (AE Title, IP, Port) under Settings → DICOM. Use Query/Retrieve (C-FIND/C-MOVE) to search and download studies.
3. Cloud/URL sources: If MIView supports cloud storage, add account credentials in Settings → Cloud and import studies via the cloud browser.

3. User interface overview

• Study Browser (left): Lists patients, studies, and series. Use the search bar to filter by patient name, ID, or accession number.
• Viewer Canvas (center): Displays selected series. Multiple viewports possible (1×1, 2×2, 1×3, etc.).
• Tools Toolbar (top/right): Measurement, window/level, annotations, MPR, cine, and more.
• Metadata Panel (right/bottom): Shows patient and series DICOM fields (modality, slice thickness, acquisition date).

4. Basic navigation controls

• Scroll through slices: Mouse wheel, up/down arrow keys, or scroll bar.
• Zoom: Mouse wheel with Ctrl, or pinch gesture on touchpads. Alternatively, select Zoom tool and drag.
• Pan: Click-and-drag with middle mouse button or hold Space while dragging.
• Window/Level: Click Window/Level tool then drag up/down (level) and left/right (width), or use preset window buttons (e.g., Brain, Lung, Abdomen).

5. Common tools and how to use them

1. Measure distance/angle: Select Distance or Angle tool, click endpoints (or three points for angle). Read measurements in the overlay or metadata panel.
2. ROI and histogram: Draw ROI to measure mean, SD, area, and view pixel value histogram. Useful for quantitative assessment.
3. Annotations: Add text labels or arrows; toggle visibility when exporting images.
4. Cine playback: For dynamic studies (e.g., cardiac cine), use the play/pause controls and adjust frame rate.
5. Multi-planar reconstruction (MPR): Open MPR mode to view orthogonal planes (axial, sagittal, coronal). Adjust slab thickness and reformat angle.
6. 3D rendering (if available): Use Volume Rendering or Surface Rendering. Adjust transfer function, opacity, and shading for optimal visualization.
7. Fusion/Overlay: Register and overlay PET/CT or MRI/PET series; adjust opacity and colormap for combined interpretation.

6. Advanced workflow features

• Comparative review: Load prior studies side-by-side; synchronize scrolling and window/level between series.
• Hanging protocols: Save viewport layouts and series matching rules to auto-arrange studies on load.
• Presets and hotkeys: Configure measurement presets and keyboard shortcuts for faster review.
• Scripting and automation (if supported): Use built-in scripting or API to batch-export series, anonymize studies, or generate reports.

7. Exporting and reporting

• Export images: Save as DICOM, PNG, JPEG, or TIFF. Choose options for overlays, annotations, and compression.
• Export DICOM series: Use Export → DICOM Send to push to another DICOM node or PACS.
• Create reports: Use the report module to add findings, measurements, and key images. Export report as PDF or structured report (SR) if supported.

8. Settings and personalization

• Display: Adjust default window/level presets, font sizes, and viewport backgrounds.
• Performance: Enable GPU acceleration, adjust cache size, and set image prefetching preferences for large studies.
• Privacy: Use anonymization tools before exporting or sharing studies; configure default anonymization profiles.

9. Troubleshooting tips

• If studies fail to load, verify file integrity and that DICOM tags (PatientID, StudyInstanceUID) are present.
• For PACS connectivity issues, double-check AE Title, IP, and port; ensure firewall rules allow DICOM traffic.
• If rendering is slow, enable GPU acceleration or reduce rendering quality/slab thickness.

10. Quick-start checklist

1. Install MIView and grant permissions.
2. Configure DICOM node and test Query/Retrieve.
3. Open a sample study and practice scrolling, window/level, and measurements.
4. Try MPR and cine for multi-planar/dynamic cases.
5. Save a hanging protocol and export a report as PDF.
