Penalized maximum-likelihood reconstruction for improving limited-angle artifacts in a dedicated head and neck PET system

Positron emission tomography (PET) suffers from limited spatial resolution in current head and neck cancer management. We are building a dual-panel high-resolution PET system to aid the detection of tumor involvement in small lymph nodes (
