3D Multiplanar reconstruction (MPR)

 

The 3D MPR tool provided within the RadiAnt DICOM Viewer can be used to reconstruct images in arbitrary planes (oblique). This can help to create a visualization of the anatomy that would not be possible using base images alone.

Opening the 3D MPR window

 

1. Open the volume series in the 2D viewer window and click the  MPR  button on the toolbar and then  3D MPR . Alternatively, you can use the  F2  shortcut.

2. After the series is loaded into memory and preprocessed, the 3D MPR representation will be displayed in a new window. This process can take a few seconds on slower systems.

Some series cannot be used with the 3D MPR tool (e.g., images with nonparallel planes).

If the images are not spaced evenly within the volume, the missing slices will be interpolated, and some visual artifacts may appear in presentation and measurements.

 

Note, some larger series (e.g., >2000 CT images) require more than 1GB of free memory and the 64-bit RadiAnt DICOM Viewer version to load successfully.
