Description

Technical Field

[0001] This invention relates to the field of radiation equipment technology, and in particular to a DR adjustment device. Background Technology

[0002] Radiation equipment refers to devices that generate or utilize radiation or radioactive energy for work or experiments. They are primarily used in fields such as medical diagnosis, treatment, industrial testing, and scientific research. Common radiation equipment includes radiation therapy machines, fluoroscopy machines, nuclear magnetic resonance (MRI) scanners, and radioactive isotope instruments. These devices utilize the properties of radiation to help doctors diagnose diseases, treat cancer, detect material defects, and analyze sample composition. During installation, radiation equipment requires adjustment and support devices to ensure its stability.

[0003] During DR (Digital Radiography) imaging, if the X-rays emitted by the X-ray source do not strike the flat panel detector perpendicularly, several problems can occur that affect image quality: 1. Image distortion: This distortion usually manifests as changes in the shape or size of objects in the image, such as objects appearing longer or shorter; 2. Reduced sharpness: Non-perpendicular X-rays affect image sharpness and detail display. This is especially noticeable at edges, where blurring may occur; 3. Affected contrast: Due to the angle between the X-ray and the detector, some areas may exhibit uneven contrast due to varying X-ray intensity, potentially obscuring important diagnostic information; 4. Edge halos: When the X-ray source and detector are not properly aligned, halos or additional light spots may appear at the edges, affecting the overall image quality.

[0004] Therefore, to obtain optimal imaging results and diagnostic information, it is essential to ensure that the X-ray source and detector are accurately aligned, with the X-rays perpendicular to the detector. However, when operating portable DR equipment in complex terrain in the field, the unpredictable environment necessitates frequent adjustments to the equipment's position and angle to adapt to uneven ground or other environmental factors. This not only increases operational complexity but may also affect the stability of the imaging equipment. Furthermore, manual adjustments are not only time-consuming but can also lead to operational errors, impacting imaging quality and efficiency. Summary of the Invention

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The purpose of this invention is to provide a DR adjustment device to solve the problems existing in the prior art, thereby improving the device's adaptability in extreme environments and enhancing its stability and imaging accuracy.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] This invention provides a DR adjustment device, such as... Figure 1-3As shown, the device includes a transmitter adjustment mechanism and an image acquisition device adjustment mechanism. The transmitter adjustment mechanism includes a first support frame and a vertical adjustment assembly. The first support frame includes a first support plate 1 and a first leg disposed below the first support plate 1 for supporting the first support plate 1. A level 26 is disposed on the top surface of the first support plate 1. The vertical adjustment assembly includes an L-shaped connecting rod 25 and a ball joint mechanism 4. The ball joint mechanism 4 includes a ball seat 36, a ball head 37, and a connecting rod 38. One end of the L-shaped connecting rod 25 is fixed to the top surface of the first support plate 1, and the other end is fixedly connected to the ball seat 36. The ball seat 36 has a cavity and a first opening and a second opening communicating with the cavity. The first opening is located on the bottom surface of the ball seat 36. The ball head 37 is placed in the cavity and can rotate within the cavity. Part of the ball head 37 protrudes from the first opening into the cavity and connects to the connecting rod 38. The other end of the connecting rod 38 is fixedly connected to the launching device 5. The locking member can be inserted into the cavity from the second opening and abut against the ball head 37, thereby preventing the ball head 37 from moving relative to the cavity. The image acquisition device adjustment mechanism includes a second support frame, which includes a second support plate 19 and a second leg set below the second support plate 19 for supporting the second support plate 19. The second leg includes at least three support rods distributed along the circumferential direction. The support rods are telescopic structures. A level 26 and a column 27 are provided on the top surface of the second support plate 19. The image acquisition device 28 is installed on the top of the column 27. A calibrator 29 for calibration is provided on the top of the image acquisition device 28. After the first tripod is placed on uneven ground in the field, the ball joint mechanism 4 of the vertical adjustment component allows the transmitting device 5 to remain perpendicular to the horizontal ground due to gravity. Then, the locking component prevents the ball head 37 from moving relative to the cavity, allowing the transmitting device 5 to automatically adapt to and remain stable in different terrain environments, making operation simple. After the second tripod is placed on uneven ground in the field, the second support plate 19 is kept horizontal by adjusting the support rod of the telescopic structure. The calibrator 29 can scan the transmitting device 5 and further adjust the image acquisition device 28 to the target height to achieve focusing. This ensures that the height of the image acquisition device 28 matches that of the transmitting device 5, meaning that the rays emitted by the transmitting device 5 can be perpendicularly irradiated onto the image acquisition device 28, improving the stability and accuracy of imaging, as well as the quality and efficiency of imaging.

[0033] In a further preferred embodiment of the present invention, the L-shaped connecting rod 25 includes a vertical rod 2, a horizontal rod 3, and a first driving mechanism.

The first driving mechanism includes a first motor 6 and a first lead screw 7 fixedly connected to the output shaft of the first motor 6. The first motor 6 is fixedly mounted on the first support plate 1. The horizontal rod 3 has a threaded hole that is threadedly engaged with the first lead screw 7 and a through hole that is slidably engaged with the vertical rod 2. By driving the first lead screw 7 to rotate through the first motor 6, the horizontal rod 3 drives the transmitting device 5 to slide on the vertical rod 2 due to the torque exerted by the rotation of the first lead screw 7. This achieves the function of adjusting the height of the transmitting device 5, making it easier to match the height of the image acquisition device 28 with that of the transmitting device 5. That is, the rays emitted by the transmitting device 5 can be perpendicularly irradiated onto the image acquisition device 28, improving the quality and efficiency of imaging.
