A c-arm ct device with high sensitivity

Abstract

The invention discloses a high-sensitivity C-arm CT device, which belongs to the field of photoelectric imaging. A high-sensitivity C-arm CT device includes a CT detector assembly. The CT detector assembly includes a detector protective shell, which is flexible and telescopic. The outer end of the shielding ring is connected with a number of matching load-bearing buffer components. Through the cooperation of the load-bearing buffer component, flexible telescopic shielding ring and isolated push component, it can effectively block the interference of the X-ray receiving plate and assist The cooler promotes the heat dissipation of the X-ray receiving board, effectively reducing the degree of temperature interference to the X-ray receiving board, thereby improving the stability of the signal conversion of the X-ray receiving board, improving the sensitivity of the CT detector components, and effectively improving the C-arm CT equipment. The image quality of the main body can effectively reduce the energy of X-rays, reduce the damage caused by the C-arm CT equipment main body to the patient's body, and improve the safety of the C-arm CT equipment main body.

Description

technical field [0001] The invention relates to the field of photoelectric imaging, more specifically, to a C-arm CT device with high sensitivity. Background technique [0002] With the continuous advancement of medical technology and the rapid development of precision medicine, the medical industry has made higher requirements for medical imaging technology. Among them, the wide application of C-arm CT equipment can provide more accurate medical treatment for today's medical technology. Image assistance, non-invasively used in patient intervention, orthopedic imaging, trauma, plastic surgery, urology and other medical departments. [0003] The imaging accuracy of the C-arm CT equipment directly affects the doctor's diagnosis, so it needs to have high image quality and good resolution. The most direct way is to improve the image quality of the C-arm CT equipment by increasing the X-ray energy. , but high-intensity X-ray radiation is easy to cause damage to the patient's bod...

AI Technical Summary

Problems solved by technology

[0004] In actual use, the CT detector is extremely susceptible to interference from external light, vibration, magnetic field and electric field, and thus cannot effectively stabilize its detection accuracy and affect the subsequent image quality. The existing technology adopts a sealed alloy box for CT The internal components of the detector are wrapped and isolated to achieve the effect of blocking interference, but the sealed alloy box directly affects the heat dissipation of the internal components of the CT detector while blocking the interference, and it is easy to reduce the temperature of the CT detector during long-term use. Sensitivity, and thus can not achieve the purpose of effectively improving the graphics quality
