Description

Technical Field

[0002] In recent years, with the continuous advancement of medical imaging technology, computed tomography has become one of the important tools in medical imaging diagnosis. CT technology generates a large number of two-dimensional tomographic images by performing multi-angle X-ray scans on the human body, providing doctors with detailed anatomical structure information. However, traditional two-dimensional CT images only provide information on surface structures, which limits doctors' comprehensive understanding of internal structures. Nowadays, in order to overcome this limitation, three-dimensional modeling technology has emerged. Three-dimensional modeling technology can convert two-dimensional CT image data into a real three-dimensional anatomical model, providing more comprehensive and accurate structural information.

[0037] In an optional embodiment: a second slide groove 12 is opened on the inner wall in the middle of the bottom end of the base 1, and a linkage plate 13 is slidably connected to the inner wall of the second slide groove 12.
