[0002] CT is computer tomography, which uses a precisely collimated X-ray beam and a highly sensitive detector to scan a certain part of the human body one section after another, thereby detecting the patient's physical lesions. There is a large inspection ring hole in the center of the CT machine. During the inspection, the patient is driven by the inspection bed into the inspection ring hole of the CT machine for X-ray beam and other scans. When performing chest and abdominal CT examinations, the patient needs to hold his breath to achieve an effective CT examination. The entire breath-holding process is about ten seconds, and it is often necessary to hold the breath two or three times. Patients are physically unwell due to illness, and some patients have to go through a lot of hospitalization examinations, which has caused serious anxiety, especially the elderly and children. When they lie on the CT machine examination bed and slowly enter the huge inspection ring hole of the CT machine, their anxiety and fear will increase. Moreover, they are in the CT machine while holding their breath, and they don't know when the breath-holding will end. There are huge medical equipment sounds around them. Such unknowns amplify the negative emotions of tension, anxiety, and fear, which bring great psychological discomfort to patients, causing their heart rate to accelerate, affecting breath-holding, and even causing artifacts in CT imaging, hindering the smooth progress of CT examinations.

[0018] Reassurance during the CT scan: Patients need to hold their breath during chest or abdominal CT scans. At this time, their heads are outside the working area of the CT machine and they can see the display screen. When the CT scan begins, the examination bed slowly moves the patient into the CT machine. At this time, many patients, especially the elderly and children, will feel very nervous and anxious. The projector projects soothing language and videos on the screen. The relevant videos may include precautions during the CT scan, etc. The control screen emits gentle soothing sounds or cartoon animation sounds to soothe the patient's emotions, distract the patient's attention, and reduce anxiety. The soothing sounds may include some precautions for the CT scan, etc. When it is necessary to hold your breath, the screen will display the breath-holding start reminder, breath-holding countdown, and words encouraging the patient to hold his breath, so that the patient knows the breath-holding time and reduces the fear brought by the unknown.
[0019] The screen automatically adjusts its angle: as the examination bed moves, the position of the patient's head keeps changing. At this time, the camera captures the moving image of the bed and transmits the movement of the bed to the control system. The control system determines the moving direction of the bed and transmits the start control signal to the wireless signal transceiver and control module of the adjustment motor through the wireless signal transceiver module, thereby controlling the adjustment motor to rotate forward or reverse. When the adjustment motor rotates, the bevel gear II drives the bevel gear I to rotate, causing the threaded rod to extend and retract, pushing or pulling the upper part of the curtain forward. Since the threaded rod and the inner rod are connected to the curtain through a universal joint, the curtain swings at this time, ensuring that the patient can see the curtain clearly.
[0020] The technical solution of the present invention has the following beneficial effects:
[0021] 1. The present invention can project words and pictures that soothe the patient's emotions on the CT machine through the cooperation of the screen and the projector, and prompt the start time of breath holding and count down the remaining time of breath holding, so that the patient can master the process of breath holding, eliminate the fear brought by the unknown, reduce the anxiety brought to the patient by the CT machine equipment, and help the patient to perform effective CT examination.
[0022] 2. The present invention can fix the screen on the CT machine by assembling a movable fixing device and a spring fixing device. It is simple and convenient to use, will not damage the CT machine, and is easy to disassemble and assemble.
[0023] 3.
