Abstract: A radiation detector includes a sensor panel, a scintillator panel, a reflective layer, and a radiation irradiation detecting photodetector laminated in this order from a side of a radiation receiving surface. Radiation transmitted through a patient's body enters the scintillator panel through the sensor panel, and is converted into light.

Apart of the light reaches the sensor panel, while the remains reach the reflective layer. The light reaching the sensor panel is detected by photoelectric converters. Out of the light reaching the reflective layer, a short wavelength component with a relatively high refractive index is specularly reflected to the sensor panel. A long wavelength component with a relatively low refractive index is transmitted through the reflective layer, and enters the radiation irradiation detecting photodetector, which detects a start of radiation irradiation.

Abstract: Apparatus and methods for imaging sources of gamma rays with a large area, comparatively low-cost Compton telescope (20). The Compton telescope (20) uses multiple layers (24) of low-cost organic solid plastic or liquid scintillator, arranged in large arrays of identical scintillator pixels (28). Photodiodes, avalanche photodiodes (30), or solid-state photomultipliers are used to read out the fluorescent pulses from scintillator pixels (28). Multiple scintillator pixels (28) are multiplexed into a few fast digitizers (80) and a few fast FPGA programmable digital microprocessors (78). Selection rule methods are presented for processing multiple near-simultaneous gamma ray collisions within the Compton telescope (28) to identify trackable events that yield gamma ray image data of interest. A calibration method achieves improved energy resolution along with (x,y) position information in pixels (28) made of organic scintillator materials with multiple photodetectors (30).

Abstract: An Absorption Biased (AB) methodology for NDIR gas sensors is used with a single infrared source and a detector to detect a single gas of interest by using a motion device to change the path length between that of the signal and reference channels. As in the case of the AB designed NDIR gas sensor, the ratio of the output of the Signal channel, measured during location arrangement X, over that of the Reference channel, measured during location arrangement Y, will be used to process the gas measurement. Multiple gases of interest can be detected by using one detector to detect multiple gases and/or by locating a second detector to detect multiple gases more distant from the source than the first detector, thereby creating longer path lengths for the second detector.
