Direct converting detector element for detector of detector module for detecting X-ray radiation for computer tomography scanner, has diode made of semiconductor material whose hardness is selected from specific periods of periodic table

摘要

The element (11) has strip-type diodes aligned according to an installation situation of the element with a diode longitudinal direction along an emission direction (13). Each diode is made of semiconductor material i.e. gallium arsenide, whose hardness is more than 1 percent of a mass fraction occurring element and selected from 4 periods of the periodic table. The diode includes a PN-junction aligned across the diode longitudinal direction, where reverse voltage of the diode is designed as 50 to 500 volts. An independent claim is also included for a detector module including a power supply system.
