Advances in radiopharmaceuticals and clinical understanding have escalated the use of intraoperative gamma probes in surgery. However, most probes on the market are non-imaging gamma probes that suffer from the lack of ancillary information of the su

We are exploring a novel time- and cost-efficient approach to produce robust, large-volume polycrystalline lanthanide halide scintillators using a hot wall evaporation (HWE) technique. To date, we have fabricated LaBr 3 :Ce and LaCl 3 :Ce films (slab

Microcolumnar CsI:Tl remains a highly desirable sensor for digital X-ray imaging due to its superior spatial resolution, bright emission, high absorption efficiency, and ready availability. Despite such obvious advantages, two characteristic properti

Suppression of afterglow in co-doped CsI:Tl is found to be an order of magnitude more effective in CsI:Tl, Sm than in CsI:Tl, Eu. Rate equations predict that deep electron traps introduced by co-doping with samarium effectively scavenge electrons fro

Despite the acknowledged advantages of CsI:Tl for most scintillator applications, its use for CT and other high-speed imaging has been hindered by a high degree of afterglow in its scintillation decay. We have found that a particularly effective way

Although CsI:Tl is one of the brightest and most efficient scintillator materials ever developed, its applicability for high speed imaging is limited by its persistent afterglow. We have demonstrated that much of this afterglow can be suppressed by t

Dedicated MicroCT systems for noninvasive screening of small animals are now in routine use. However, speed of operation limits their use for functional studies. At Radiation Monitoring Devices (RMD), we are addressing this need by developing a digit
