Medical system control method, device and equipment and medium

Abstract

The embodiment of the invention discloses a medical system control method and device, equipment and a medium, and the method comprises the steps: carrying out the real-time monitoring of the movementamplitude of a subject on a bed when the medical system starts to pay off; and controlling the medical system according to the monitored movement amplitude of the subject so as to reduce the radiationdosage received by the subject. Through the technical scheme of the embodiment of the invention, the purpose of reducing the X-ray radiation dose received by the subject is achieved.

Description

technical field [0001] Embodiments of the present invention relate to intelligent medical imaging technology, and in particular to a medical system control method, device, equipment and medium. Background technique [0002] With the continuous development of medical technology, more and more medical imaging equipment (such as CT (Computed Tomography, computerized tomography)) are used in clinical In diagnosis and treatment. [0003] Taking a CT machine as an example, a CT machine generally has a frame and a bed. The gantry includes devices capable of emitting and receiving radiation, which emit radiation and convert received radiation signals into electrical signals for use in generating scan images. The bed platform is used to carry the subject (that is, the target to be scanned). Usually, after the subject is in position on the bed platform in a posture such as lying down or lying down, the bed platform moves the part to be scanned of the subject through its own movement...

AI Technical Summary

Problems solved by technology

[0004] Computed X-ray tomography relies heavily on a stationary subject. The reason is that, in order to minimize the damage caused by X-rays, only the part to be scanned is radiated. Therefore, once the part to be scanned is aligned with the ray emitting device , the subject is required to remain still until the end of the scan, otherwise the imaging quality of the scanned image will be affected, or if the subject’s movement range is too large, the image of the target scanning part will not be obtained, but the image of the non-target part A scan was performed, causing the current scan to fail

But in fact, the subject will move voluntarily or involuntarily during the scanning process, which will destroy the consistency and integrity of the projection data, and even cause artifacts in the final CT image, resulting in the failure of the current scan. Re-scanning is required, which undoubtedly increases the X-ray radiation dose received by the subject

Similarly, in the field of radiotherapy, in order to minimize the damage caused by X-rays to non-radiated parts, only the radiotherapy parts (such as lesions) are radiated. Therefore, once the radiotherapy part is aligned with the radiation emitting device, it is required If the subject keeps still, if the subject moves, the radiation cannot irradiate the radiotherapy part as it should, but irradiates the non-radiation treatment part, causing additional damage to the subject
