Description

Technical Field

[0001] The present invention relates to the field of CBCT technology, and in particular to a chest support structure positioning method, device, storage medium and computer program product. Background Art

[0002] CBCT uses cone beam scanning instead of tomographic CT fan beam scanning, and uses two-dimensional planar detectors instead of tomographic CT linear detectors. In principle, the technical logic of CBCT is that X-ray equipment uses rotational acquisition technology to achieve tomographic imaging. Therefore, as long as there are tubes and detectors, there is the potential for CBCT imaging. In particular, the popularity of flat-panel detectors has accelerated the progress of this technology. Compared with multi-row spiral CT, the advantage of CBCT is that it has a smaller voxel size and higher spatial resolution than CT. For example, the current minimum pixel unit of conventional CT is 0.5mm, while the detector is generally 139μm or less. It has a very wide and excellent dynamic range, improves the density continuity of adjacent voxels, and its imaging voxel is a perfect cube, which is far beyond the reach of CT, because the thickness of CT layers will have a negative impact on the shape of its voxels. Therefore, CBCT can achieve accurate imaging in any direction. CBCT is equipped with a fixing mechanism to fix the human head and neck.

[0003] However, the traditional fixing mechanism has the following disadvantages: The traditional fixation mechanism uses a jaw support and a head clamp to position the patient's mandible and head respectively. When the jaw support positioner is in contact with the patient, it will squeeze the soft tissue of the patient's mandible, and even cause the soft tissue to deform or even be squeezed and damaged, which reduces the comfort of the patient wearing the fixation mechanism. Summary of the invention
