Method for measuring speed and high resolution information of moving object by high-speed X-ray CT, and its device

摘要

A single detector module is used both for CT imaging of two sections to measure the velocity of a moving object, and high spatial resolution measurement of a single section. A large number of slender CdTe devices are arranged to project alternately. Slits are aligned with sparsely arranged portions of the devices on both end sides of the devices, and the internal information of two sections of the moving object is simultaneously measured by detecting X-rays passing through the slits. The internal information of the two sections is again simultaneously measured after a very short time interval, and the speed of the moving object is obtained by comparison. A densely arranged portion of the CdTe devices can be used for high spatial resolution measurement of the object by exchanging the slits.
