Embodiment 1

[0032] When existing X-ray imaging equipment emits X-rays, irradiation parameters need to be adjusted so as to achieve an optimal irradiation dose. In the prior art, when adjusting the irradiation parameters, it is often adjusted according to the operator's experience and according to different irradiation objects and irradiation parts, so as to determine a range value.

[0033] This embodiment provides an X-ray-based precise measurement and imaging system, including a thickness measurement module for real-time measurement of the thickness of the irradiated object; it also includes a thickness measurement module for receiving the thickness value sent by the thickness measurement module, and bringing the thickness value into the device. The corresponding exposure parameters are obtained from the EI standard range table, and then the X-ray imaging module emits X-rays for imaging. The X-ray imaging module is a complete X-ray imaging device, and the EI standard range table is pre-...

Embodiment 2

[0036] This embodiment provides an X-ray-based precise measurement imaging system, including a thickness measurement module and used to accept the thickness value sent by the thickness measurement module, and bring the thickness value into the established EI standard range table to obtain the corresponding exposure parameters An X-ray imaging module that then emits X-rays for imaging. The X-ray imaging module is a complete X-ray imaging device, and the EI standard range table is pre-written.

[0037] Wherein, the emission parameters include working tube voltage and working tube current product.

[0038] The working tube voltage is the voltage at both ends of the cathode filament and the anode target of the ball tube in the existing X-ray equipment, which can accelerate the electron excitation on the filament and flow to the anode target. The working tube voltage determines the quality of the X-ray, that is, the penetrating power.

[0039] The current product of the working t...

Embodiment 3

[0045] This embodiment is optimized and defined on the basis of the above-mentioned embodiment 2, and the X-ray receiving and imaging module is a flat panel detector.

[0046] The thickness measurement module includes a distance measuring unit coplanar with the X-ray emitting end of the X-ray imaging module and a thickness calculation unit connected to the distance measurement unit. The thickness calculation unit calculates the irradiated object according to the distance value detected by the distance measurement unit in real time. The thickness value is input into the X-ray imaging module.

[0047] The thickness measurement module mainly calculates the distance between the X-ray generating end of the X-ray imaging module and the surface of the irradiated object. Because when the irradiated object is a fixed target, the irradiated object will be fixed on a movable plate and moved to a suitable position, and the cross bullseye on the beam beamer will be aligned with the irradia...

Abstract

The invention discloses an accurate measurement imaging system based on X-ray. The system comprises a thickness measuring module for measuring the thickness value of an irradiated object in real time,and further comprises an X-ray imaging module for receiving the thickness value sent by the thickness measuring module, substituting the thickness value into an EI standard range table to obtain corresponding exposure parameters, and then emitting X-rays for imaging. According to the invention, a completely different, integrated, fully automatic, low-cost, real-time and accurate technology is used for obtaining the X-ray radiation quality required by a patient to be photographed, patient body shape data are obtained through another system independent of an original X-ray image chain by usingvisible light, near-visible light, ultrasound, etc., and corresponding exposure parameters are acquired by checking the EI standard range table to guide an X-ray tube to emit X-rays of corresponding radiation quality.

Description

technical field [0001] The invention belongs to the technical field of X-ray imaging, and in particular relates to an imaging system for adjusting exposure parameters through thickness values. Background technique [0002] X-rays, also known as Roentgen rays, are invisible to the naked eye, but they can cause some compounds to fluoresce or make photographic negatives sensitive; they do not deflect in electric or magnetic fields, and can reflect, refract, interfere, Diffraction, etc.; it has the ability to penetrate substances, but its penetration ability is different for different substances; it can ionize molecules or atoms; it can destroy cells. Different tissues of the human body have different sensitivities to X-rays, and the degree of damage is also different. different. Therefore, X-rays can make the human body form an image on the screen or film, which is based on the difference in density and thickness of human tissue. The reason why X-rays can make the human body ...
