PET-CT Fusion Mode

Overview​

PET-CT Fusion mode in OmegaAI is a specialized feature designed for integrated imaging, allowing simultaneous visualization of PET (Positron Emission Tomography) and CT (Computed Tomography) scans. This guide details the activation process and functionalities of PET-CT Fusion mode, focusing on its interface, navigation, and advanced visualization options.

Activation of PET-CT Fusion Mode​

  1. Starting Condition: Ensure that two viewports are displayed side by side; one should display a PET image, and the other a CT image.

  2. Triggering Fusion Mode:

    • Look for the PET-CT Fusion activation option when both images are visible side by side.

    • Activate PET-CT Fusion mode by selecting this option, which typically appears in one of the viewports.

Interface and Functionality​

Upon activation, the screen layout adjusts to accommodate PET-CT Fusion:

  • Main Fusion Viewport: Occupies half of the screen, displaying the fused image of PET and CT data. By default, this view is set to the axial mode, but can be switched to sagittal or coronal views via icons located at the top left of the viewport.

Multi-Viewport Layout​

  • Additional Views: Alongside the main fusion viewport, up to four smaller viewports show various perspectives or standalone images, enhancing the analytical capabilities.

Save Measurements in Fusion Mode​

  • All ROI measurements performed in Fusion mode on the study can be automatically saved within the active session.

  • Measurements taken in the Fusion Mode would remain preserved even after exiting the mode.

  • When the same study is reopened in Fusion mode, the saved measurement details are displayed on both the image overlay and in the Measurements panel on the right.

Additional Options​

  • Fusion View Adjustments: Similar to NPR mode, tools for changing the slab thickness and rotating around the axis are available, ensuring precise and customizable visualization.
