Description

technical field [0001] The invention relates to an X-CT detection device based on cone rays. Background technique [0002] X-CT is X-ray computerized tomography. It uses precisely collimated X-ray beams and highly sensitive detectors to perform cross-sectional scans around the affected parts one by one. It has the characteristics of fast scanning time and clear images. At present, CT detection is widely used in many fields such as medicine, industry, and materials. [0003] In recent years, cone-beam CT using area array detectors has gradually entered the practical stage. Compared with other geometric structures, the cone beam CT system has high spatial resolution, short data acquisition time, and high ray utilization efficiency. The current cone beam CT system mainly has two geometric structures. One scanning ray beam is a complete cone beam, using the standard cone beam reconstruction algorithm; the other scanning ray beam is a half cone beam, using a modified reconstruc...

Compared with other geometric structures, the cone beam CT system has high spatial resolution, short data acquisition time, and high ray utilization efficiency. The current cone beam CT system mainly has two geometric structures. One scanning ray beam is a complete cone beam, using the standard cone beam reconstruction algorithm; the other scanning ray beam is a half cone beam, using a modified reconstruction algorithm, this structure is mainly used in emerging mammary gland inspection systems, with the continuous development of image computing technology In-depth, human body materials and other testing equipment using this technology are constantly being developed. At present, due to the multi-layer and multi-faceted testing of materials in material testing equipment, current testing equipment often cannot accurately measure data information.
