DETECTOR DEVICE, COMPUTER TOMOGRAPHY SYSTEM WITH TWO ENERGY LEVELS AND METHOD OF DETECTING USING SAID SYSTEM Russian patent published in 2016 - IPC G01N23/83 

FIELD: medicine.

SUBSTANCE: invention can be used for computer tomography. Core of invention is thateach detector assembly contains at least one unit of detecting crystals having the first energy characteristic and a unit having the second energy characteristic, both of which are located along the first direction in intervals, herewith each unit of detecting crystals with the first/second energy characteristic includes at least one detecting crystal having the first/second energy characteristic arranged along the second direction. At least one unit of detecting crystals having the first energy characteristic and at least one unit of detecting crystals having the second energy characteristic are located, at least partially, alternating along the first direction when viewed from the side of the direction of incidence of the X-ray beam. Present invention also discloses a system of CT with two energy levels containing a detector device and a method of CT detection using the said system.

EFFECT: technical result is provision of high spatial resolution for recovery of CT imaging with optimum number of units of detecting crystals.
