The Gammex 490 PET CT multi-modality phantom allows users to perform QC tests on both modalities with the same phantom. CT QC tests can be performed to check for alignment, positioning, CT number accuracy, slice thickness, high and low contrast and CT number uniformity. Inserts containing different size spheres allow for “hot” spot activity testing, and different inserts also allow for attenuation testing. The phantom is portable and made of solid water and acrylic.
Multimodality Phantom Takes PET, CT QC Tests
Example of a patient with an upper left lung NSCLC: A: FDG; B: FDG PET/CT; C: Planning radiotherapy based on FDG (66Gy) with BTVm (GTV), CTV and PTV; D: PET FMISO E: FMISO PET/CT; F: boost based on the FMISO PET (76Gy) with BTVh (biological hypoxic target volume) and PTV boost.
