Description

Technical Field

[0001] This utility model relates to the field of medical equipment testing technology, specifically to a device for testing the focal spot of an X-ray tube. Background Technology

[0002] The X-ray tube is a core component of X-ray imaging equipment, and the size and shape of its focal spot directly affect image quality and diagnostic accuracy. X-ray imaging technology is widely used in medical diagnostics, industrial inspection, and other fields, making focal spot testing of the X-ray tube particularly important. Accurate measurement of the X-ray tube's focal spot parameters helps ensure the quality and performance of the imaging equipment.

[0003] Currently, there are two main methods for testing the focal spot of X-ray tubes on the market:

[0004] (1) Optical method: The focal point of the X-ray tube is directly observed and measured using optical instruments. The advantage of this method is that it is relatively simple to operate, but due to the resolution limitation of the optical system, it cannot meet the requirements for high-precision focal point measurement; ambient light, reflection and the error of the optical system itself will affect the measurement results, resulting in unstable data.

[0005] (2) Digital Detector Method: This method uses a high-resolution digital detector to directly capture X-ray images, and then uses computer software for image analysis and processing. The advantages of this method are high accuracy and speed, but digital detectors are expensive, increasing testing costs; the equipment is complex, requiring highly skilled operators; and it has stringent environmental requirements, necessitating constant temperature and humidity control, resulting in high detector maintenance costs. In summary, existing X-ray tube focus testing methods suffer from insufficient accuracy, complex operation, expensive equipment, and susceptibility to interference, making them difficult to widely promote in practical applications.

[0006] To address these issues, there is an urgent need for a new type of X-ray tube focal spot testing device that can simplify the operation process, reduce equipment costs, and improve testing efficiency and reliability while ensuring high precision. Utility Model Content
