In general, the Detective Quantum Efficiency, DQE, is the standard metric for assessing image quality1 of a flat panel detector (FPD). However, a single descriptor is insufficient for describing the image quality of an FPD used for clinical imaging t

Quantum-limited-dose (QLD) and noise-equivalent-dose (NED) are performance metrics often used interchangeably. Although the metrics are related, they are not equivalent unless the treatment of electronic noise is carefully considered. These metrics a

We propose a new collimator geometry, the hybrid parallel-slant (HPS) hole geometry, to improve sensitivity for SPECT imaging with large field of view (LFOV) gamma cameras. A HPS collimator has one segment with parallel holes and one or more segments

The radiation detector used in typical gamma cameras and NaI-based positron emission tomography (PET) scanners effectively positions events over most of its crystal area, but the spatial resolution begins to suffer at the edges. One reason is that th
