PCDM (technology of the account of photons for KT)

2020: The announcement of PCDM - technology of the account of photons for KT

In the middle of September, 2020 Siemens Healthineers began to implement the mode of the account of photons of PCDM in the KT-scanners to irradiate less patients and to output qualitative pictures. The technology was developed together with the French research institute of CEA-Leti technologies.

For image acquisition use the process based on technology of indirect conversion - the computer combines a set of the x-ray measurements made under different corners, for creation of images of transverse section of the scanned objects. PCDM, on the contrary, directly will transform x-ray photons to electronic signals with more high image quality at the exit. At the same time the modules PCDM count each photon that improves the relation of contrast and "noise" of the image.

According to given tests, PCDM integrated into a prototype of the computer tomograph increases resolution of pictures, reduces impact of x-ray emission on patients and reduces "noise" and artifacts, thereby increasing quality of images. These functions of the new detector are caused by unique properties of material and the optimized geometrical parameters of the detector.

The Siemens Healthineers company began to cooperate with CEA-Leti for development, production and testing of new generation of PCDM which can be built in computer tomographs. High definition and contrast of images allows specialists to consider very small structures, such as small airways in lungs, trabeculas in bones and thin a wire in coronary stents. Special functions allow the device to color with images for convenience of doctors and also to precisely define atomic number of the chemical elements which are present at an organism.^[1]
