The coincidence timing resolution is a critical performance parameter to determine if direct gamma-ray detection by semiconductor detector material such as CdTe or CdZnTe may be suitable for use in positron emission tomography systems. We report expe

Spatial variation in the background source distribution makes tumor detection difficult for single-detector probes. Using a single energy window that brackets the photopeak helps discriminate against background events dominated by Compton scattering.

The physical properties of three surgical probes containing different radiation detectors are compared: a NaI(Tl) scintillator with a flexible, fiber-optic light guide, and two semiconductor detectors that operate at room temperature, CdTe and HgI2.

Cosmic-ray nuclei have been observed to produce 2072 secondary fragments in nuclear interactions detected in nuclear emulsions. These fragments produce 557 further interactions. Previous reports that these secondary nuclei show anomalously short mean

A hand-held, dual-detector probe has been developed for surgical tumor staging. This dual probe simultaneously monitors counts from a possible tumor site along with counts from adjacent normal tissue using two concentric, collimated scintillation det

We used an observer-performance study to compare four different modes of presenting count-rate data from a radiation detector. Observers searched for small, concealed radioactive sources using a hand-held radiation-detector probe. The modes of count-

It has now been over a decade since the idea of coded apertures as an alternative to conventional pinholes and collimators was first proposed in the nuclear medicine literature. During this period, many different codes and decoding algorithms have be

We adapted a small sodium iodide scintillation detector for rapid, in vivo localization of a lost brachytherapy seed. Using the detector, we were able to locate and remove an Ir-192 seed that was not visible to the unaided eye.

A series of high-galactic-latitude observations made with the Voyager 2 ultraviolet spectrometer are used to place stringent upper limits on the far-ultraviolet emissions from the central regions of the Coma Cluster of galaxies. In particular, consid
