Objective. In carbon ion therapy, the visualization of the range of incident particles in a
patient body is important for treatment verification. In-beam positron emission tomography …

In vivo imaging of 225Ac is a major challenge in the development of targeted alpha therapy
radiopharmaceuticals due to the extremely low injected doses. In this article, we present the …

Positronium (Ps) lifetime imaging is gaining attention to bring out additional biomedical
information from positron emission tomography (PET). The lifetime of Ps in vivo can change …

Positron emission tomography (PET) is an imaging modality used for the noninvasive
assessment of tumor staging and response to therapy. PET with 18F labeled …

Positronium (Ps) is generated before electron–positron annihilation in positron emission
tomography (PET). As the Ps lifetime reflects the surrounding electron density, we aimed at …
