Cover Imaging for Physicists

6. Image contouring

Recommendations

• Any segmentation algorithm chosen for RT TP should provide

algorithmic robustness and should be parameterized to the spatial

resolution of the PET system in use.

• A validation of the delineation with phantom data should be done.

• In clinical routine, a delineation method needs to be selected and

agrees upon among imaging experts and radiation oncologists.

• Contouring should be performed jointly by two experts from

radiotherapy and nuclear medicine.
