Molecular Breast Imaging Using Synthetic Projections From High-Purity Germanium Detectors: A Simulation Study

Digital Timing Algorithm for High Purity Germanium Detectors

The next generation of γ-ray detector arrays will be composed of large volume high purity germanium (HPGE) detectors that are electronically segmented. These detectors will be able to track γ-rays as they Compton scatter within the crystal and between adjacent crystals, eliminating the need for Compton suppression detectors and improving angular resolution. The new arrays will have much higher ...

Performance Characteristics of a Third-generation Spectroscopic Vehicle Portal Monitor based on High Purity Germanium Detectors

The general need for improved detection performance and reduced decision time for portal monitors, freight container scanners, and mobile search systems is being achieved with systems utilizing High-Purity Germanium (HPGe) detectors. Highly specialized software analyzes the spectroscopic data to produce accurate results in live time. To meet the need, a new generation monitor has been developed...

Measurement of the Potassium Content of Different Food Samples with High Purity Germanium Detectors

Measurements of the potassium content of samples of food, performed with High Purity Germanium detectors, are presented in this paper. The potassium content was measured by identifying the 1460 keV photons produced in the decay of the isotope 40K. Samples were selected, for which a high potassium content was expected. The measurements confirmed the expectations qualitatively, but not always qua...

Improving 3-D Imaging Breast Cancer Diagnosis Systems Using a New Method for Placement of Near-Infrared Sources and Detectors

The objective of this research was to improve 3-D imaging system by near-infrared light emission in breast tissue to achieve a more accurate diagnosis of tumor. The results of repeated experiments in this research have shown that with this imaging system, a more accurate diagnosis of abnormal area depends on the location of the sources and detectors. Therefore, an optimal location model has bee...
