Activity painting: PET images of freely defined activity distributions applying a novel phantom technique.

PLoS ONE, 2019
The aim of this work was to develop a novel phantom that supports the construction of highly reproducible phantoms with arbitrary activity distributions for PET imaging. It could offer a methodology for answering questions related to texture measurements

In vivo production of fluorine-18 in a chicken egg tumor model of breast cancer for proton therapy range verification

Scientific Reports, 2022
Range verification of clinical protontherapy systems via positron-emission tomography (PET) is not a mature technology, suffering from two major issues: insufficient signal from low-energy protons in the Bragg peak area and biological washout of PET ...
