The purpose of this article was to make the reader more familiar with the basic principles and techniques of new photon counting ct (pcct) systems equipped with photon counting detectors and also to describe the currently available devices that could be used in clinical practice. 2. technical background.

Photon counting performance can also be implemented for imaging devices by using image intensifiers, which are usually based on a microchannel plate behind a photocathode. avalanche photodiodes (apds) can be operated in the geiger mode for photon counting. they are then called single photon avalanche diodes (spads). here, the applied reverse. Photon counting detectors made of a semiconductor crystal which allows the detection of the incoming photons individually using a direct conversion process. the spatial resolution is defined electrically and only limited by the charge distribution inside the semiconductor. this enables sharper images without the dose penalty of interpixel gaps. Photon counting ct technology engineered to enable higher contrast to noise ratio, improved spatial resolution, and optimized spectral imaging. photon counting ct technology is designed to use new, energy resolving x ray detectors to count the number of incoming photons and quantify photon energy for higher contrast to noise ratio, improved.

Los tc photon counting nos permiten eliminar el calcio de las arterias y finalizar con las limitaciones que teníamos con los pacientes con score cálcico alto. también gracias a esta resolución inigualable tenemos mucha más definición de las arterias coronarias de pequeño tamaño y podemos observar el interior de los stent. The news that superconducting nanowire detectors can detect single photons with a timing precision of just a few picoseconds will benefit applications ranging from sensing to quantum communications.
