WebMar 20, 1989 · It is shown that the Glauber correlation functions accounting for the velocity of photocounting do not satisfy the causality principle — the most important condition of a correct theory. It mostly concerns the velocity of photocounting of impulse signals. It is shown that every impulse follows a precursor having no physical meaning which is ... WebExact photocounting distributions are obtained for a pulse of light whose intensity is exponentially decaying in time, when the underlying photon statistics are Poisson. It is assumed that the starting time for the sampling interval (which is of arbitrary duration) is uniformly distributed. The probability of registering n counts in the fixed time T is given in …

Photon-counting computed tomography (PCCT) is a form of X-ray computed tomography (CT) in which X-rays are detected using a photon-counting detector (PCD) which registers the interactions of individual photons. By keeping track of the deposited energy in each interaction, the detector pixels of a PCD … See more Often EIDs are used as a baseline for comparison when evaluating PCD performance capabilities. With this lens, there are several potential advantages of using a PCD over using an EID in CT imaging. These … See more Discrete energy-dependent detection When a photon interacts in a PCD, the amplitude of the resulting electrical pulse is roughly proportional to the photon energy. By comparing each pulse produced in a pixel with a suitable low-energy threshold, … See more Classical CT reconstruction The fundamental challenge of tomographic reconstruction is the inverse problem of reconstructing the 3D, tomographic information of a … See more Experimental PCDs for use in CT systems use semiconductor detectors based on either cadmium (zinc) telluride or silicon, neither of which … See more
