Overview​

Hanging Protocols in the OmegaAI Image Viewer now go well beyond flat 2D stacks. This release adds MPR, rotating PET MIP, and PET-CT fusion viewports; smarter, metadata-driven series matching; and four new default protocols built around them.

What's New​

1. MPR, Rotating PET MIP & PET-CT Fusion Viewports​

What changed:​

Hanging Protocol viewports are no longer limited to a flat 2D stack. Seven new view codes let a viewport open directly into an advanced view as soon as a study loads, with no manual setup:

• CT: MPR Axial / Coronal / Sagittal — builds a multiplanar reconstruction from the thinnest axial CT series in the chosen plane. Even an axial-only CT can open as coronal or sagittal.
• PT: PET 3D MIP — a rotating whole-body PET projection, built automatically from the attenuation-corrected PET series.
• PET-CT: Fusion Axial / Sagittal / Coronal — PET overlaid on CT in the chosen plane, using the PET display preset's colormap.

Slab thickness and projection (Maximum, Average, or Minimum Intensity) can be saved for each MPR and fusion viewport, so the viewport opens exactly as configured. If a study can't support one of these views, the viewport shows the best available 2D series instead of going blank — for fusion, it shows CT alone with a "Fusion unavailable" indicator.

Benefit:​

Radiologists land on the right multiplanar or fused view automatically — no manual reconstruction or series hunting required.

2. Display Presets for Every Modality​

What changed:​

Each viewport's rules now include a single Display Preset picker, listing the presets available for that viewport's modality — CT, MR, US, PT, NM, and more, not just PET as before. Selecting a preset applies its window level and, where configured, its colormap and auto-windowing behavior together.

Benefit:​

Consistent, clinically correct windowing and colormaps on open, authored once and reused across every protocol.

---

3. Smarter, Metadata-Driven Series Matching​

What changed:​

Viewport matching rules can now weigh study details beyond modality and body part — slice thickness, study description, and dozens of other fields — with numeric and multi-value comparisons. Each rule can be a strict requirement or just a preference, so OmegaAI still hangs the best available series rather than leaving a viewport empty.

Benefit:​

Protocols can express real clinical preferences — like favoring a primary-read series over a thin reconstruction — without ever risking a blank viewport.

---

4. Four New Default Hanging Protocols for PET, PET-CT, and MPR​

What changed:​

OmegaAI's Default Hanging Protocol catalog adds four new protocols: PET Default, PET-CT Default, PET-CT Quick Read, and MPR Default, each built around the new viewport types above. PET and PET-CT cells apply a clinically standard SUV-scaled colormap, and fall back safely with a clear indicator when a study's data can't support SUV scaling.

Benefit:​

PET, PET-CT, and MPR-heavy workflows get a clinically reviewed, ready-to-use starting protocol out of the box.

---

Important Notes​

• Backward compatible: Existing protocols behave exactly as before, with no impact on studies that don't use the new viewport types.
• Series matching: A condition on a metadata field that doesn't apply to the bound series simply never matches — it doesn't cause an error.
• SUV safety fallback: A "SUV unavailable" indicator with hidden SUV stats is expected behavior when a study's DICOM metadata can't support SUV calculation — it isn't an error.

---

Where to Find It​

• MPR, PET 3D MIP & Fusion view codes: Hanging Protocol Configuration → View Codes panel → drag CT: MPR Axial/Coronal/Sagittal, PT: PET 3D MIP, or PET-CT: Fusion Axial/Sagittal/Coronal onto a viewport
• Display Presets & series matching: Hanging Protocol Configuration → select a viewport → HP Rules tab
• New Default protocols: Image Viewer → Quick Access Strip or Layout Panel → PET Default / PET-CT Default / PET-CT Quick Read / MPR Default

Overview​

Window Level presets in the OmegaAI Image Viewer are now tailored to the modality you're actually viewing, replacing the old CT-centric preset list that used to appear on every study type regardless of modality.

What's New​

1. Presets Filtered by Modality​

What changed:​

The Window Level preset list is now filtered to the modality being viewed — CT, MR, US, PT, NM, and more each get their own relevant list, instead of a single generic CT-centric list showing up everywhere.

Benefit:​

Every modality gets presets that are actually clinically relevant to it, so you're never scrolling past irrelevant CT presets on an MR or ultrasound study.

---

2. Corrected CT Presets & Auto-Windowing for Other Modalities​

What changed:​

CT presets like Brain, Stroke, Mediastinum, Soft Tissue, and Abdomen now use corrected clinical values, with a new Subdural preset added. Modalities where a fixed window doesn't make sense — MR, US, CR/DX, and NM — now default to auto-windowing strategies instead, calculated from the image data itself.

Benefit:​

Presets reflect current clinical standards, and modalities that never suited fixed numeric values now window correctly by default.

---

3. Compound Presets for PET & Nuclear Medicine, Mammography Support​

What changed:​

PET and Nuclear Medicine presets now apply window level and color map together in a single selection (Hot Iron, Hot Metal Blue, PET Rainbow, Cool, Inverted Gray), with correct SUV-unit windowing. Mammography gains sigmoid VOI LUT support, with correct handling of "For Presentation" vs. "For Processing" images.

Benefit:​

One click gets you the correct look for PET/NM studies, and mammography windowing now matches how those images are meant to be displayed.

---

4. Three-Tier Preset Configuration​

What changed:​

Presets now resolve through three tiers — System defaults, Organization overrides, and User overrides — so administrators and individual radiologists can customize presets without losing the underlying system defaults.

Benefit:​

Organizations and individual readers can fine-tune presets to their own preferences without breaking the baseline for everyone else.

---

Important Notes​

• Backward compatible: All original CT preset names are preserved, so existing Hanging Protocols referencing them by name continue to work unchanged.

---

Where to Find It​

• Window Level Presets: Image Viewer → Window Level tool → preset dropdown (filtered to the active viewport's modality)

Overview​

This release brings a set of improvements across the OmegaAI Image Viewer, Hanging Protocols, and the Mobile Image Viewer — including a new stage-navigation option for Hanging Protocols, modality-aware display presets, persistent Cine playback preferences, a refined viewport scrollbar, and improved landscape mode on mobile.
