[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0017] Example Reference Figures 1-4 This is an embodiment of the present invention, which provides a multifunctional phantom for performance testing of dental CBCT equipment, comprising: The load-bearing mechanism 100 includes a fastener 101; The testing mechanism 200 includes a lifting assembly 201 disposed on the top of the fixing member 101, and a testing assembly 202 disposed on the surface of the lifting assembly 201.

[0018] Specifically, the fastener 101 includes a base 1011 and a universal locking wheel 1012 fixedly installed at the bottom of the base 1011.

[0019] It should be noted that the base 1011 is designed to have sufficient stability and weight to ensure that the entire device will not move easily during use. Meanwhile, the omnidirectional locking wheels 1012 not only allow the support mechanism 100 to be easily moved to different positions, but also enable it to lock quickly when needed, providing stable support.

[0020] Specifically, the lifting assembly 201 includes a telescopic rod 2011 fixedly connected to the base 1011, and a limit lock 2012 disposed on the surface of the telescopic rod 2011.

[0021] It should be noted that the telescopic rod 2011 is made of high-strength, lightweight materials, ensuring that it is both robust and easy to operate. The limit lock 2012, in conjunction with the limit holes on the surface of the telescopic rod 2011, can precisely adjust and lock the height of the test assembly 202, thereby adapting to testing tasks with different height requirements.

[0022] Specifically, the test assembly 202 includes a thermometer 2021 disposed on the surface of the telescopic rod 2011, a mouthpiece 2022 disposed on the surface of the thermometer 2021, and a display 2023 disposed on the surface of the telescopic rod 2011.

[0023] It should be noted that the thermometer 2021 is integrated inside the mouthpiece 2022 to ensure the accuracy of temperature measurement. The mouthpiece 2022 simulates the real human oral cavity environment, helping to obtain CBCT scan data that is closer to reality. The display 2023 not only displays the data from the thermometer 2021 in real time, but also provides a user-friendly interface for easy monitoring and recording by the operator.

[0024] Specifically, a limit hole is provided on the surface of the telescopic rod 2011, and the limit hole fits with the outer end face of the limit lock 2012.

[0025] It should be noted that the design of the limiting hole takes into account the convenience and stability of operation. The tight fit between the limiting lock 2012 and the limiting hole not only ensures the accuracy during the height adjustment process, but also effectively prevents accidental slippage and ensures the stability of the test component 202 in the working state.

[0026] Specifically, the mouthpiece 2022 has a shape adapted to the human oral cavity, and the display 2023 can provide data measured by the thermometer 2021 in real time.

[0027] It should be noted that the mouthpiece 2022 is meticulously designed with ergonomic principles in mind to ensure patient comfort during CBCT scans. Its material selection also prioritizes biocompatibility to avoid any discomfort or allergic reactions. The display 2023 features a high-resolution screen with excellent viewing angles, ensuring clear data display even in low-light environments.

[0028] In use, the supporting mechanism 100 is first moved to the desired position using the universal locking wheels 1012 at its bottom, and the stability provided by the base 1011 ensures that the entire device is stable and does not wobble. Next, the lifting assembly 201 is adjusted, specifically the telescopic rod 2011, to precisely adjust the height of the testing assembly 202 according to actual needs. During this process, the limit lock 2012 fits tightly with the limit hole on the surface of the telescopic rod 2011, ensuring that the position is fixed accurately after each height adjustment, thus adapting to testing tasks with different height requirements. Then, the mouthpiece 2022 is correctly placed in the patient's mouth. The mouthpiece is designed according to ergonomic principles, with a shape that conforms to the human mouth, ensuring patient comfort while simulating real human conditions for scanning. The mouthpiece integrates a thermometer 2021, which monitors and records intraoral temperature changes in real time. This is crucial for assessing image quality. Simultaneously, the display 2023 shows the data measured by the thermometer 2021 in real time, providing the operator with intuitive feedback and supporting data storage and export functions for subsequent data analysis and report generation. Throughout the process, the position of the testing component 202 is optimized by adjusting the lifting assembly 201, ensuring the mouthpiece 2022 is in the optimal scanning position to obtain high-quality CBCT images. Furthermore, this multifunctional phantom not only helps detect key performance indicators such as spatial resolution, density resolution, uniformity, and artifacts, but also further improves diagnostic accuracy by monitoring the impact of factors such as temperature changes on image quality in real time. Ultimately, this comprehensive and meticulous operating procedure and design concept ensures that the oral CBCT equipment can provide reliable and accurate imaging support in clinical applications, greatly improving patient safety and satisfaction.

[0029] In summary, through the cooperation of the support mechanism 100 and the detection mechanism 200, users can conveniently and accurately adjust the detection component 202 to the ideal height suitable for different patients or detection needs, effectively ensuring repeatability and imaging accuracy in each scan. This structural design enhances the stability and precise positioning capability of the overall device, keeping the phantom stable during use and avoiding image deviations caused by displacement. This not only significantly improves the quality and reliability of CBCT images but also further enhances diagnostic accuracy and patient treatment outcomes, providing more efficient and stable technical support for clinical applications.
