Description

Technical Field

[0002] Portable X-ray imaging systems are a type of radiological diagnostic instrument, which is a type of medical imaging equipment designed to be easily moved and used between different locations. This type of X-ray machine is usually lighter and more compact than traditional fixed-mount X-ray machines, and can be used almost anywhere as long as the power supply allows, including different departments of the hospital, emergency rooms, operating rooms, intensive care units, the field or disaster sites. X-ray imaging systems include X-ray emitters and detectors. The X-ray beam generated by the X-ray emitter passes through the patient's body or the object under examination. Different tissues absorb X-rays to different degrees, resulting in different X-ray intensity distributions after transmission. The detector receives the X-rays and converts the received X-rays into visible light, and then the photodiode further converts these visible lights into electrical signals. These signals are converted into digital data after analog-to-digital conversion and generate digital images.

The user sets and controls various parameters of X-ray emission through the operation panel 103. After the setting is completed, the host unit 202 receives the control signal and starts the X-ray emission process. The X-ray emitter 101 emits X-rays, which pass through the protective cover 102 and human tissue and are then received by the detector 201. The protective cover 102 limits the emission path of the X-rays and protects the emission head of the X-ray emitter 101 to prevent damage. The detector 201 converts the received X-rays into electrical signals, and the host unit 202 is responsible for processing the X-rays from the detector 201. The electrical signal of the detector 201 is first converted into digital form, and then the data is processed using a built-in software algorithm, including filtering, enhancement, and pseudo-coloring steps, to ultimately generate a digital image that can be used for clinical diagnosis.

When the lifting mechanism 800 is working, the output shaft of the dual-axis self-locking motor 810 drives the rotating rod 811 to rotate, and the rotating rod 811 drives the lifting gear 812 to rotate on the surface of the limit rod 813 to adjust the height of the fixed plate 801. The fixed plate 801 drives the rotating mechanism 700 to move up and down to change the shooting height. When the rotating rod 811 moves up and down, it drives the limit sleeve 814 to slide on the surface of the limit rod 813 to limit the fixed plate 801.

[0043] By setting up a mobile cart 804, the X-ray imaging system can be moved. The frame 803 is pushed to move by the handle 807, and the frame 803 drives the fixed frame 808 and the mobile cart 804 to move synchronously. The mobile cart 804 moves on the ground through the brake universal wheel 806, and the counterweight 805 counterweights the top of the mobile cart 804 to prevent the X-ray imaging system from tilting.

[0044] The X-ray imaging structure includes an X-ray emission module 100, a detection module 200, a multi-angle adjustment arm 300, an interval distance adjustment mechanism 400 and a quick release mechanism 500, and the bearing structure includes a locking mechanism 600, a rotating mechanism 700 and a lifting mechanism 800. When outdoor shooting is required, the X-ray imaging structure is separated, and the user quickly removes the quick release mechanism 500 from the inside of the locking mechanism 600, and then removes the interval distance adjustment mechanism 400, the multi-angle adjustment arm 300, the detection module 200 and the X-ray emission module 100 for outdoor use. When used inside the hospital, the quick release mechanism 500 is reinstalled in the locking mechanism 600 to improve the flexibility of the X-ray imaging system. The height and vertical angle of the X-ray imaging structure are adjusted by the rotating mechanism 700 and the lifting mechanism 800, and the X-ray imaging structure can be moved by the lifting mechanism 800 to meet the needs of different departments.
