CT SCANNERSSOFTWARE BALANCINGMULTIPLE DETECTORSThe general requirements for balancing of detectors in a multiple detectorCTscanner are discussed, and the specific requirements for software balancing using data acquired within the body section during the scan are outlned. A particular technique which can ...
Scan profiles across a trap detector in two orthogonal directions at 2.52 THz. Full size image 2.2 Novel single-element detectors Another interesting concept developed to realize a flat absorption in the FIR was published as long ago as 1934 [10]. The concept is based on the solution of Maxwe...
In this paper, we promote a new scheme known as hybrid detectors that combine the dynamic-threshold-based counting and integrating modes. In this scheme, an energy threshold can be dynamically changed during a spectral CT scan, which can be considered as compressive sensing along the spectral ...
When the development of perovskite X-ray detectors is advanced to the pixelated imager with a single readout of X-ray scan, the system level characterization metrics for spatial resolution and noise performance such as modulation transfer function, noise power spectrum, and detective quantum ...

After the registration process volumes of interest (VOI) for striatum, putamen, caudate and an occipital background region are superimposed on the SPECT scan. The VOIs are then used for SBR calculation according to the following formula: SBR of region = (mean count density in region-of-...
Photon flux for the first scan is chosen as the maximum possible value not saturating the detector in the low attenuation areas. The second exposure level is calculated from the data acquired in the first exposure, assuming that the detector response to the incoming radiation is linear. To ...
Figure 4a shows the spatially averaged image sensor signal of all pixels in the array as a function of light intensity for different reverse bias voltage over the photodiode and two image scan rates, 2 and 4 frames per second (fps). The average light intensity is changed by keeping the dri...
“The industrial market is rapidly changing. New requirements are coming in from the automotive industry, especially for inspection of large castings, electronics, and batteries. We have been pioneers in providing CT and line scan solutions for industrial customers and are now even better...
A method for photon count-loss calibration in a computed-tomography (CT) scanner, including capturing incident X-ray photons via a plurality of energy-discriminating detectors, dete
