From: Prediction of VMAT delivery accuracy with textural features calculated from fluence maps
Fluence maps of head and neck (H&N) volumetric modulated arc therapy (VMAT) plans generated with the (a) Trilogy and (b) TrueBeam STx systems. Fluence maps of a (c) prostate boost VMAT plan generated with the Trilogy system and (d) that of lung stereotactic ablative radiotherapy (SABR) VMAT plan generated with the TrueBeam STx systems. Fluence maps were generated by the superposition of all fluences at each control point and normalized to pixel values ranging from 0 to 127
