Embodiment Construction

[0016] When using CT technology for interventional treatment, the patient is located figure 1 On the examination table 300 shown, the examination table 300 moves into the gantry hole 110 for scanning inspection. The doctor controls and monitors the CT scanning process through the image control system, such as setting scanning parameters. The collected scan data is reconstructed by the image reconstruction system to generate a reconstructed image, and the reconstructed image is displayed.

[0017] figure 2 It is an interface diagram for controlling the X-ray emission range in the present invention. In CT interventional treatment, doctors usually stand on the left or right side of the examination table to perform surgical operations for the patient. Since the patient is lying on the examination bed, looking from the direction facing the gantry, if the X-ray tube running along the surface of the gantry (ie the operation of the gantry) is regarded as a clock-like rotation, the doct...

Abstract

The invention provides a method for controlling the emission of X-rays in a CT interventional therapy. An X-ray tube rotates around a patient and gains the data of the patient; the X-ray tube is closed within a setting range which is the range of the hands of a doctor when the CT interventional therapy is performed; the X-ray tube is closed within the range through setting a starting point and an angle, an end point and an angle, or a center point and an angle. The method reduces the irradiation on the hands by the X-rays emitted from the X-ray tube as much as possible when the doctor acts the CT interventional therapy through setting the closing range of the X-ray tube, thereby effectively protecting the hands of the doctor.

Description

Technical field [0001] The invention relates to a control method, in particular to a method for controlling X-ray emission in CT interventional therapy. Background technique [0002] CT intervention technology is a technology that uses CT as a guiding device for fine needle aspiration biopsy or treatment. It is guided by a CT machine, and a specific device is introduced into the diseased part of the human body for treatment through a tiny wound or human cavity. Because it does not require surgery and has the advantages of high positioning accuracy and fewer complications, CT interventional technology has been widely used in more and more medical fields. [0003] A typical CT equipment such as figure 1 As shown, a gantry 100 is included, and in the gantry 100 there is a turntable 200 that rotates for scanning and inspection. A rack hole 110 is provided in the rack 100, and the turntable 200 rotates around the rack hole 110. The patient lies on an examination bed 300 arranged in f...
