Automatic CT ray protection system

Abstract

The invention discloses an automatic CT ray protection system. The system comprises a console with a control display panel, a CT scanner and a driving mechanism, wherein the CT scanner comprises a scanning bed, a radiation source and a high-sensitivity detector. When a detection preparation button of the control display panel is triggered, the scanning bed, the radiation source, the detector and aprotection cover are driven by the driving mechanism to be automatically adjusted to initial positions, the position of a patient is detected by a contact sensor array, the position information is sent to the console and displayed on the control display panel, and a detection part is selected through the control display panel. Based on the position information of the patient and the selected detection part information, the protection cover is driven to move, so that the center of a transparent window of a cover body is aligned to the initial position of the to-be-detected part, and with the exception of the detection part, the other parts are shielded. When a detection button on the control display panel is triggered, the scanning bed is driven by the driving mechanism to be automaticallyadjusted to a detection position, the radiation source and the detector are started, a movable bed body, the radiation source and the detector are controlled to longitudinally and synchronously movealong the bed body, and collection of computed tomography scanning data of the detection part is completed. By means of the system, the technical problem that in the CT examination process, the ray radiation protection is poor is solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a CT ray automatic protection system. Background technique [0002] With the rapid development of medical detection technology, tomography (CT) has been more and more widely used due to its ability to detect lesions in milliseconds. CT detection technology uses precisely collimated X-ray beams, γ-rays, ultrasound, etc. , together with highly sensitive detectors, do end-face scanning one by one around the various parts of the human body. It has the characteristics of fast scanning time and clear images, and can be used for the inspection of various diseases. However, as we all know, radiation has a great impact on the human body. Severe radiation, because only specific parts of the patient's body are checked during the inspection, those parts that do not need to be inspected will inevitably be exposed to radiation, and these rays will cause certain damage after being absor...
