Recently, the authors derived an uncertainty relationship between noise and spatial resolution in linear computational imaging systems that is similar to the Heisenberg uncertainty principle for conjugate variables in quantum mechanics. Specifically, for linear shift-invariant systems with a fixed incident photon density, the product of noise and spatial resolution has a positive absolute lower limit...
Continuous miniature crystal element (cMiCE) detectors are a potentially lower cost alternative to high resolution discrete crystal designs. We report on the intrinsic spatial resolution performance for two cMiCE PET detector designs with depth of interaction (DOI) positioning capability. The first detector utilizes a 50 mm by 50 mm by 8 mm LYSO crystal coupled to a 64 channel, multi-anode PMT. It...
The quality of imaging systems is usually expressed using the modulation transfer function (MTF). MTF is also used to express the quality of transmitted images through a random medium. The resolution, as well as MTF, is essentially dependent on the properties of such media. Transmitted images are often affected by the presence of particulate matter (aerosol, dust, fog) and turbulence between object...
