2D Multiplanar reconstruction (MPR)

Scroll Prev Top Next


The MPR tool provided within the RadiAnt DICOM Viewer can be used to reconstruct images in orthogonal planes (coronal, sagittal, axial or oblique, depending on what the base image plane is). This can help to create a visualization of the anatomy which was not possible using base images alone.




Click the  MPR  button on the toolbar, and select the plane you would like the series to be reconstructed to (the current plane of source series is checked and grayed out).




Alternatively, keyboard shortcuts below can be used to switch planes.

 Ctrl + Alt + 2 


 Ctrl + Alt + 3 



This process takes 1-2 seconds on a fast machine, but can be substantially slower on computers with less memory.


If the button is grayed out, the MPR tool cannot be applied to the series (e.g. in case of images with nonparallel planes).





One series can be reconstructed in three planes in order to easily localize an area of interest thanks to cross-reference lines.

Use the screen splitting tool to open three panels, and drag the source series thumbnail into each of them.

Click first panel to activate it, and then select the new image plane using the MPR tool. Repeat this step for the second panel.
