Background

The medical imaging department refers to a technique and a process for obtaining an image of an internal tissue of a human body or a part of the human body in a non-invasive manner for medical treatment or medical research. It contains the following two relatively independent directions of study: medical imaging systems and medical image processing. The former refers to the process of image formation, including the research on the problems of imaging mechanism, imaging equipment, imaging system analysis and the like; the latter refers to further processing of the acquired images, either to restore the original less sharp image, to highlight some feature information in the image, to classify the pattern of the image, or the like. The radiation-proof lead screen is a device capable of blocking and protecting electromagnetic radiation of a medical imaging department.

The two sides of the bottom of a traditional medical image protective device such as a radiation-proof lead screen are both connected with two universal wheels, and when the screen is parked, a single universal wheel needs to be locked, so that the operation is inconvenient.
