Abstract

The invention discloses a double-source energy spectrum CT high-resolution imaging device and method.The double-source energy spectrum CT high-resolution imaging device is installed on a CT slip ring rotating support and comprises a high-energy imaging assembly and a low-energy imaging assembly; each of the high-energy imaging assembly and the low-energy imaging assembly comprises an X-ray emitting device for emitting X-rays, and an amorphous silicon detector and an amorphous selenium detector for collecting digital images. According to the invention, the amorphous silicon detector and the amorphous selenium detector are used, the amorphous silicon detector and the amorphous selenium detector are combined into a larger detector, the amorphous silicon detector and the amorphous selenium detector carry out imaging independently and reconstruct three-dimensional data, the spatial resolution of an image reconstructed by the amorphous selenium detector is higher, and the detection precision is higher. The density resolution of the image reconstructed by the amorphous silicon detector is higher, the two groups of images are fused after reconstruction is completed, and the fused image can keep higher spatial resolution and can also guarantee better density resolution.

Description

technical field [0001] The invention belongs to the technical field of radiotherapy, and in particular relates to a dual-source energy spectrum CT high-resolution imaging device and method. Background technique [0002] Dual-energy CT technology refers to the use of two X-ray sources with different energy spectral distributions to scan the object to be detected, to obtain the original data scanned under two different energy spectral distributions, and then use these data, through the corresponding image processing algorithm, Reconstruct the atomic number, electron density, attenuation coefficient and other information of the detected object. The advantage of dual-energy CT technology is that it can not only reconstruct the attenuation coefficient image of single-energy CT imaging, but also reconstruct the atomic number and electron density information of the substance at the same time. The error introduced when the atomic number is used as a reference value for identificati...
