An anticoincidence detector is a system equipped with BGO crystals that reduces instrumental background in detectors by a factor of 20, with a threshold set at ∼75 keV, and contributes to about 12% of the deadtime in the detection system. ...

The latter property is required to cut down losses due to dead time or the time during which the detection system is ‘busy’ dealing with one interaction and thereby misses others that might occur. Theoretical predictions can be made of these properties for different materials, but good ...
An alternative method is proposed in this work by the simulation of a non-invasive coincidence detection unit. Results We utilized GATE simulations of a human forearm phantom with a blood flow model, as well as a model for dynamic radioactive bolus activity concentration based on clinical ...
(https://github.com/cortex-lab/Suite2P) and supplemented by manual drawing. However, we did not use the analysis pipeline in Suite2P after ROI detection, since we often observed over-subtraction of background signals. All ROIs were individually inspected and edited for appropriate shapes using ...
The JCC-71 system is made up of four counter banks, each composed of high-density polyethylene for the moderation of the fission neutrons. Each bank contains several3He detectors for the detection of neutrons. The counter can operate in both an active mode and a passive mode. For the passiv...
Survival of CRC is related to the stage of disease at the time of the initial diagnosis. Between 1985 and 1997, death rates of colon cancer in the United States declined slightly due to earlier detection of primary tumors, via stool blood tests, sigmoidoscopy, colonoscopy, and screening tests...
