From: Development of a bespoke phantom to optimize molecular PET imaging of pituitary tumors
Development and printing of brain and skull phantom. The CT scan of a patient (A) was used to create the surrounding brain and skull phantom by segmenting the soft tissue (red), bone (green), air (blue) and brain (pink) (B). The segments were exported as STL files and loaded into PrusaSlicer (C) for printing (D). Following printing of the two halves (E, F), the radioactive pituitary gland ± tumor were inserted into the pituitary fossa (red arrow in panel F). Thereafter, the two halves were brought together (G) before filling with radioactivity via the ports (yellow arrow in panel G)
