Viewer tips for Cardiac CT

Consider the following tools and tips when reviewing Cardiac CT studies

preload study

Preload Study

Preloading a study activates additional viewing functions and provides a smoother workflow, improved performance, and an overall more efficient review experience.

MPR – Multiplanar Reconstruction

Multiplanar Reconstruction (MPR) enables you to reformat volumetric datasets into different anatomical planes.

 

How to Open MPRMPR MIST oblique

  • Tip: Start with the Axial CT Series using a 1×1 layout

  • Select MPR from the toolbar

  • Choose MIST Oblique or use the shortcut Shift + Q to enable

  • Double Oblique Projections then possible to freely adjust two angles.
  • Toggle viewports to best suit reconstruction

  • Switch between different MPR viewport layouts to best suit.



Double Oblique Projection MPR

  • Use the green, red, and blue cross-hair lines to scroll, angle and refine regions of interest

Options

  • MIP (Maximum Intensity Projection) – highlights high‑density structures such as contrast-filled vesselsimage-png-Sep-11-2024-12-54-19-1118-PM

  • minIP (Minimum Intensity Projection) – enhances low‑density areas like airways

  • AVG (Average Intensity Projection) – blends voxel intensities for a smoothed representation

Thickness

Use the slider to adjust the thickness and refine the projection results. Thicker slabs increase structure visibility, while thinner slabs preserve fine detail.
