Photon counting detector energy response
WebApr 19, 2024 · In the case of Gotthard-1.7, the energy conversion gain g necessary to convert from ADC units into energy can be estimated by a linear fit of the peak position as a function of the photon energy. For a photon-counting detector like Mythen-II, the energy conversion is extracted by a linear fit between the position of the inflection point of the ... WebBackground: While spectral CT using single photon counting detector has shown a number of advantages in diagnostic imaging, knowledge of the detector response function of an energy-resolved detector is needed to correct the signal bias and reconstruct the image more accurately. Objective: The objective of this paper is to study the photo counting …
