Compared with X-ray tomography, the main advantages of ct are

There is no interference and overlap of out-of-plane tissue structure.

CT imaging overcomes the overlapping phenomenon of tissues and organs and the interference of scattered rays, and improves the resolution of tissue and organ density through image reconstruction calculation, which is the most important feature of CT.

There is no out-of-plane tissue overlap, while conventional tomographic images are overlapping images of in-plane images and out-of-plane interference images that are not completely erased, and there is no real thickness.
