Description

Technical Field

[0001] This utility model relates to the field of X-ray machine technology, and more specifically to a desktop X-ray machine. Background Technology

[0002] Currently, DR (digital radiography) is based on X-ray imaging technology, which directly digitizes the attenuated signal of X-rays after they pass through an object, thereby generating high-resolution two-dimensional images suitable for rapid diagnosis and screening. However, it only supports generating two-dimensional images and has certain limitations; overlapping structures cannot be clearly viewed.

[0003] TOMO (Tomography-Assisted Imaging) generates three-dimensional images, accurately identifying the location of lesions within objects and improving diagnostic precision, but at a higher cost and with a higher radiation dose. TOMO acquires images through multi-angle scanning and then synthesizes these images into three-dimensional data, providing more accurate spatial positioning and internal structural information. This helps doctors gain a comprehensive understanding of the lesion from multiple perspectives, improving diagnostic accuracy and enabling better diagnosis. It is particularly effective for complex cases such as tumors and fractures, enhancing diagnostic accuracy. Enhanced visual effects and image fusion allow doctors to clearly identify the location, size, and shape of lesions, avoiding misdiagnosis due to depth information that cannot be presented in two-dimensional images.

[0004] The main principle of commonly used X-ray machines is that electrons emitted from the cathode of the X-ray tube bombard the rotating anode target to form X-rays, such as the X-ray machine with prior art publication number CN217907798U.

[0005] Existing DR and TOMO products on the market are expensive and bulky. Therefore, we are launching a multi-functional DR that combines the imaging capabilities of both DR and TOMO, leveraging their respective advantages to meet various imaging needs in clinical diagnosis and treatment. Utility Model Content

[0006] To overcome the aforementioned deficiencies in the prior art, this utility model provides a desktop X-ray machine that synthesizes three-dimensional images through the collaboration of an X-ray source and a flat panel detector, facilitating the viewing of lesion details. The desktop compact design reduces the product's size and can meet the clinical needs for two-dimensional and three-dimensional imaging. Furthermore, the use of an arc-shaped track and a linear motor slide rail to adjust the positions of the X-ray source and the flat panel detector respectively enhances the product's flexibility and solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a desktop X-ray machine, including a base, with a mounting groove on the top of the base. A flat panel detector assembly and a stage are disposed inside the mounting groove. The stage is positioned above the flat panel detector assembly. The flat panel detector assembly includes a flat panel detector, which is fixedly mounted in the mounting groove via a linear motor slide rail. An X-ray assembly is fixedly mounted on the rear side of the top of the base. The X-ray assembly includes an X-ray source, and an arc-shaped track is slidably connected to the rear end of the X-ray source. The bottom end of the arc-shaped track is fixed to the top of the base via a column.

[0008] In a preferred embodiment, the column includes a hollow column fixed to the top of the base, and a telescopic column is slidably provided inside the hollow column. The bottom end of the telescopic column is connected to the bottom wall of the hollow column by a compression spring.

[0009] In a preferred embodiment, the rear end of the hollow column is threaded with two vertically distributed fastening bolts for fixing the telescopic column.

[0010] In a preferred embodiment, rectangular openings are provided on both sides of the top front end of the mounting groove. A lever is hinged inside each of the two rectangular openings, and the rear end of the lever contacts the front end of the stage. This is used to seal the rectangular openings to prevent dust and debris from contaminating the flat panel detector and affecting its subsequent detection.

[0011] In a preferred embodiment, the top two sides of the stage are provided with slots that are adapted to the lever. The lever is inserted into the slot to reinforce the stage and prevent the stage from shaking and opening, which would affect the safety of the flat panel detector.

[0012] In a preferred embodiment, both dial plates have grooves on their tops, and pull rods are fixedly installed inside the grooves. Both dial plates are locked to the base by a lock, and the lock is located in front of the groove to improve the firmness between the dial plates and the base.

[0013] In a preferred embodiment, extension plates are connected to both sides of the base, allowing for the adaptation of objects of different lengths by adding extension plates.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model synthesizes three-dimensional images by working together with an X-ray source and a flat panel detector, which facilitates the viewing of lesion details. The desktop compact structure design reduces the product size and can meet the two-dimensional and three-dimensional imaging needs of clinical imaging. The position of the X-ray source and the flat panel detector are adjusted by using an arc track and a linear motor slide rail, thereby improving the flexibility of this product.

[0016] 2. The rectangular opening is sealed by a baffle plate to prevent dust and debris from contaminating the inside of the mounting slot and affecting the subsequent use of the flat panel detector. At the same time, the baffle plate can reinforce the stage, thereby improving the stability of the stage and preventing the stage from opening automatically and causing damage to the flat panel detector.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Refer to the instruction manual appendix Figures 1-5This utility model provides a desktop X-ray machine, including a base 1. The top of the base 1 has a mounting groove 2. The mounting groove 2 is provided with a flat plate detection component 3 and a stage 4. The stage 4 is located above the flat plate detection component 3. The flat plate detection component 3 includes a flat plate detector 31. The flat plate detector 31 is fixed in the mounting groove 2 by a linear motor slide rail 32. An X-ray component 5 is fixedly provided on the rear side of the top of the base 1. The X-ray component 5 includes an X-ray source 51. The rear end of the X-ray source 51 is slidably connected to an arc-shaped track 52. The bottom end of the arc-shaped track 52 is fixed to the top of the base 1 by a column 53.

[0027] In practical use, the operator places the base 1 on a table, then places the object to be tested on top of the stage 4. The X-ray source 51 emits rays that penetrate the target object. Based on X-ray imaging technology, the attenuation signal of the X-rays after passing through the object is directly digitized, thereby producing a high-resolution two-dimensional image for easy viewing of lesion details. Simultaneously, the X-ray source 51 can slide and change position on the arc-shaped track 52 at the top of the column 53, and the linear motor slide rail 32 in the mounting slot 2 drives the flat panel detector 31 to move below the stage 4. This allows the X-ray source 51 and the flat panel detector 31 to work together to acquire projection data from multiple angles. The flat panel detector 31 records the intensity changes of the rays emitted by the X-ray source 51 after passing through the object. Then, by correcting the acquired projection data to remove noise, background interference, and errors from the flat panel detector 31, a reconstruction algorithm is used to restore the projection data to a slice image of the target object. The entire device adopts a desktop compact design, reducing product size and meeting the needs of clinical two-dimensional and three-dimensional imaging.

[0028] In this embodiment, the column 53 includes a hollow column 531 fixed to the top of the base 1. A telescopic column 532 is slidably provided inside the hollow column 531. The bottom end of the telescopic column 532 is connected to the bottom wall of the hollow column 531 through a compression spring 533. The rear end of the hollow column 531 is threaded with two vertically distributed fastening bolts 534 for fixing the telescopic column 532.

[0029] When the staff loosens the fastening bolt 534, the telescopic column 532 rises out of the hollow column 531 under the elastic force of the compression spring 533, so that the staff can quickly adjust the height of the X-ray source 51. When it is necessary to lower the height of the X-ray source 51, the staff only needs to press down. The structure is simple and the adjustment is very time-saving and labor-saving.

[0030] In this embodiment, extension plates 12 are also connected to both sides of the base 1. The extension plates 12 are connected to the base 1 using bolts. The staff can choose to install the extension plates 12 according to the actual situation, which is suitable for objects of different lengths.

[0031] Refer to the instruction manual appendix Figure 4 The mounting groove 2 has rectangular openings 6 on both sides of the top front end. The two rectangular openings 6 are hinged with a lever 7 inside. The rear end of the lever 7 is in contact with the front end of the platform 4 to seal the rectangular openings 6 and prevent dust. The platform 4 has grooves 8 on both sides of the top end that are adapted to the lever 7. The lever 7 is inserted into the groove 8 to reinforce the platform 4.

[0032] Furthermore, a groove 9 is provided on the top of each of the two levers 7, and a pull rod 10 is fixedly installed inside the groove 9. Both levers 7 are locked to the base 1 by a lock 11, and the lock 11 is located in front of the groove 9.

[0033] When staff need to inspect and maintain the flat panel detector 3 inside the mounting slot 2, they first open the lock 11 and flip the lever 7 open. Then, they can insert their fingers into the rectangular opening 6 and flip the platform 4 open to inspect and maintain the flat panel detector 3. When closing the platform 4 again, they use the two levers 7 to reinforce the platform 4 to prevent it from opening automatically. At the same time, they seal the rectangular opening 6 to prevent dust and debris from falling into the mounting slot 2 and contaminating the flat panel detector 31.

[0034] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
