3D printing of radioactive wall-less PET phantoms improves threshold-based target delineation and quantification

Abstract Background Validation of threshold-based PET segmentation and PET quantification is typically performed with fillable phantoms. Theoretical considerations show that the inactive walls of the phantom cavities introduce a contrast dependence of the volume-reproducing threshold (VRT), potentia...
