matRad_visPhotonFieldShapes

Purpose ^

matRad function to visualize imported field shapes from a dicom RTPLAN

Synopsis ^

function matRad_visPhotonFieldShapes(pln)

Description ^

 matRad function to visualize imported field shapes from a dicom RTPLAN
 data. Note that this only works with pln structures that were generated
 with matRad's dicom import tool and feature the appropriate field shape
 information
 
 call
   matRad_visPhotonFieldShapes(pln)

 input
   pln: matRad plan struct

 output
   -
