Description

Technical Field

[0001] The utility model relates to the technical field of X-ray detection, in particular to a quality control and protection detection model of animal digital X-ray photography equipment. Background Art

[0002] As veterinary medicine has advanced, imaging examinations have become increasingly important. To ensure the accuracy of imaging results, specialized quality control tools are required to regularly inspect digital X-ray equipment. However, current quality control tools can only inspect personnel equipment and cannot inspect animal X-ray diagnostic and treatment equipment for the following reasons: 1. Digital X-ray equipment for personnel can be used for horizontal, vertical, or special rotational projection modes, while X-ray radiography in fixed rooms in animal hospitals only has vertical projection capabilities. 2. The beam conditions for digital X-ray field equipment in fixed rooms in animal hospitals for animals (primarily small and medium-sized animals such as pet dogs, cats, and birds) are lower than those for personnel, and fixed beam conditions are used. Furthermore, during radiation protection inspections around the equipment room, due to the inconsistency between the conditions issued and the subjects being inspected, it is also necessary to distinguish between scattering phantoms for personnel and animal radiation sites.

[0003] Currently, there are no national standards for quality control of digital animal X-ray equipment and radiation protection for personnel. (GBZ 130-2020, "Radiation Protection Requirements for Diagnostic Radiology," is a personnel protection standard and does not apply to animal medical institutions; T / ACEF 117-2023, "Radiation Protection and Safety Requirements for Animal X-ray Diagnosis," does not specify specific requirements for test phantoms. Therefore, given the unique characteristics of animal digital X-ray equipment and facilities, it is necessary to provide a phantom for quality control and protection testing of animal digital X-ray equipment to ensure that the quality of the equipment meets the requirements for veterinary diagnosis of animal diseases while also enabling radiation protection testing of the facility.

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. Unless otherwise specified, the devices, components, etc. used in this application are all commercially available products.

[0025] like Figure 1-5 As shown, a quality control and protection detection model of animal digital X-ray equipment includes a water model 1.

[0026] The water model 1 of the present application can specifically use a 40cm×40cm×15cm water tank, with a water inlet pipe 4 connected to the upper side of the water tank. When filling the water tank with water, the water tank can be tilted, and the water inlet pipe 4 can be placed upwards. Water enters the water model 1 from the water inlet 41 of the water inlet pipe 4 and fills the water model 1. Then a plug is inserted into the water inlet 41 to seal the water model 1, and then the water model 1 is placed upright. In order to prevent the presence of bubbles in the water model 1 when the model of the present application is in use, thereby affecting the accuracy of the test results, the present application also connects an air storage branch pipe 42 to the water inlet pipe 4. The air storage branch pipe 42 is set upward, and the top of the air storage branch pipe 42 is closed. After the water model 1 is filled with water and closed, if there are bubbles therein, the water model 1 can be tilted in the direction in which the air storage branch pipe 42 is set, so that the bubbles in the water model 1 enter the air storage branch pipe 42. At this time, there are no bubbles in the water model 1, which will not affect the final test results. In addition, when the mold body of the present application is not in use, a plug can be used to seal the water inlet 41 to prevent dust, impurities, etc. from entering the mold body and affecting subsequent use.

[0027] An upper lead point 6 and a lower lead point 7 are provided in the center of the upper and lower surfaces of the water phantom 1, respectively. The upper lead point 6 and the lower lead point 7 are located on the central axis of the water phantom 1. The upper lead point 6 and the lower lead point 7 can be used to detect the verticality of the X-ray field emitted by the digital X-ray imaging system.

[0028] The digital X-ray equipment phantom of the present application includes, in addition to the water phantom 1, various types of detection plates that are compatible with the water phantom 1. The various types of detection plates can be placed above and / or below the water phantom 1. To facilitate the placement and positioning of the detection plates, the present application provides an upper limit plate 2 and a lower limit plate 3 above and below the water phantom 1, respectively. Slots for inserting the detection plates are formed between the upper limit plate 2 and the water phantom 1, and between the lower limit plate 3 and the water phantom 1.

[0029] Specifically, the upper and lower limit plates 2 and 3 have the same structure. For example, the upper limit plate 2 includes side baffles 21 connected to three sides of the upper surface of the water mold 1. The upper edges of the side baffles 21 extend toward the center of the water mold 1 to form an upper baffle 22. The height of the side baffles 21 is designed to be slightly higher than the thickness of the test plate, and the area of ​​the test plate is the same as the area of ​​the upper surface of the water mold 1. Once the test plate is inserted into the slot, it can be ensured that there is no movement of the test plate in the slot, thereby achieving a fixed position for the test plate.

[0030] The detection plates of the present application are divided into three types, namely the first detection plate 9, the second detection plate 10 and the third detection plate 11. Specifically, one piece of the first detection plate 9 is provided, and a cross lead wire 91 is provided in the center thereof for determining the size of the left and right boundaries of the irradiation end (light field). One piece of the second detection plate 10 is provided, and a low contrast resolution module 101 and a high contrast resolution module 102 are provided thereon. The low contrast resolution module 101 includes a plurality of blind holes 1011 of the same diameter and different depths, which are used to test the low contrast resolution of the X-rays emitted by the digital X-ray equipment system; the high contrast resolution module 102 includes lead wires 1021 arranged in a fan shape, which are used to test the high contrast resolution of the X-rays emitted by the digital X-ray equipment system. Two pieces of the third detection plate 11 are provided, and a groove 111 of the same shape as the detector is formed thereon. The groove 111 forms a notch on one side of the third detection plate 11 for leading out the connecting wire of the detector. After placing the detector in the groove 111 of the third detection plate 11 , two third detection plates 11 are placed above and / or below the water model 1 respectively, which can be used to detect the radiation dose received by the water model 1 .

[0031] The present application also provides a number of supporting feet 5 at the bottom of the water model 1. Preferably, three supporting feet 5 are provided, which are symmetrically distributed on the lower limit plate 3 at the bottom of the water model 1. Setting the supporting feet 5 on the lower limit plate 3 will not affect the action of inserting the detection plate into the slot. In addition, the supporting feet 5 also have the function of adjusting the horizontal placement of the water model 1. Specifically, the supporting feet 5 include a first screw 51, an adjustment block 52, a second screw 53 and a base 54. The first screw 51 is fixed on the lower limit plate 3, and the second screw 53 is fixed on the base 54. A threaded hole is formed in the adjustment block 52. The first screw 51 and the second screw 53 are respectively inserted into the threaded holes from the upper and lower sides. By screwing the adjustment block 52, the depth of the first screw 51 and the second screw 53 inserted into the adjustment block 52 can be adjusted, thereby adjusting the level of the water model 1. In addition, a level bubble 8 is provided on the water model 1 of the present application, which can be used to indicate the level of the water model 1.

[0032] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
