The embodiments of the invention relate to a CT (Computed Tomography) data positioning method. The method comprises the steps: providing a fixed support (1), a rotary frame (2), a radioactive scanningsource (3), a radioactive signal receiving unit (4), a scanning bed (5) and a laser radar (6); acquiring 3D image features of a scanned object through the laser radar (6); determining diagnostic local feature information according to the 3D image features, wherein the local feature information comprises position feature information and volume feature information of a local region; and starting upthe radioactive scanning source and the radioactive signal receiving unit, and scanning the local region, thereby obtaining diagnostic data of the local region. According to the method, a 3D scanningradar is arranged, a three-dimensional image of a human body is acquired firstly through the laser radar during CT scanning, then, an accurate scanning position and dimension information are determined firstly, and then, accurate CT scanning is carried out; and by the method, a step that all traditional computed tomographs need to carry out scanning after carrying out positioning by a plain filmis omitted, and the radiation dosage of a sufferer is lowered.
Description
technical field [0001] The invention relates to the technical field of medical computed tomography, in particular to a CT data positioning method. Background technique [0002] CT (Computed Tomography), also known as computerized tomography equipment. With the development of technology, CT machine has gradually developed from the traditional slice imaging method, that is, imaging in the rotation plane (here called X-Y plane), to volume imaging method, that is, continuous imaging in the direction of the rotation axis (here called Z direction). imaging. [0003] The traditional CT machine operation first needs to scan the plain film to locate the patient's part, so as to determine the accurate scanning position, and then perform the next step of tomographic or helical scanning according to the patient's information. In terms of radiation dose, the plain film scan is an auxiliary scan for locating patient information, not a necessary scan for diagnosing the patient's conditio...
