Detector Innovation for PET: Demonstrated 1‑Mm Rod-Resolution Brain PET and Extension to Whole‑Body PET
The spatial resolution of current PET systems, typically around 4 mm, remains far from the theoretical limit of 1-2 mm primarily determined by photon non‑collinearity. Achieving PET resolution closer to that of CT and MRI would enable earlier disease detectio...

Parametric Imaging of Washout In Range‑Verification Open PET: Clinical Demonstration of Tumor Diagnosis during Carbon‑Ion Therapy
Tumor oxygenation plays a critical role in treatment response and progression. However, repeating PET with hypoxia-specific radioligands at every treatment fraction is not practical. Tumor-vascular status, by contrast, can be assessed by measuring the washout...
