Description

Technical Field

[0001] The present invention relates to the field of CT detection technology, and in particular to a dual-energy low-dose CT imaging and lesion analysis and diagnosis device. Background Art

[0002] Dual-energy low-dose CT imaging and lesion analysis and diagnosis equipment is an advanced medical imaging device that integrates dual-energy imaging technology and low-dose radiation technology. It can generate high-quality images of the human body and accurately analyze and diagnose lesions. Dual-energy imaging technology is a highlight of the device. During the scanning process, two sets of X-ray sources will simultaneously emit X-ray beams of different energies to penetrate the patient's body. Due to the different absorption characteristics of different tissues to X-rays of different energies, for example, bones have relatively low absorption of high-energy X-rays and high absorption of low-energy X-rays; the absorption degree of soft tissue to the two energy X-rays is significantly different from that of bones. The detector will accurately capture the X-ray signals after passing through the human body and transmit these signals to the computer system. The computer uses complex and precise algorithms to analyze and process the X-ray attenuation data at different energies, and then generate dual-energy images with rich information. The equipment adopts a series of advanced low-dose radiation technologies. On the one hand, by optimizing the emission power of the X-ray source, it can minimize X-rays as much as possible while meeting the imaging requirements. On the other hand, the output of the radiation can be adjusted by using intelligent scanning parameter adjustment technology to automatically match the most appropriate scanning parameters according to factors such as the patient's body shape and the examination site, avoiding unnecessary high-dose scanning. After the scan, the lesion can be analyzed and diagnosed to obtain data results.

[0003] In the existing technology, dual-energy low-dose CT imaging and lesion analysis and diagnostic equipment are usually not allowed to carry magnetic materials into the equipment during use. Screening for whether patients carry metal objects mainly relies on questions from medical staff and self-information from patients. However, this method has many hidden dangers that lead to omissions. From the perspective of medical staff, when asking patients whether they carry metal objects, they may not be able to accurately understand the question due to fast speaking speed and unclear expression; or due to time constraints, they may miss the questioning process for some patients in a hurry. From the patient's perspective, some patients lack basic knowledge of the contraindications of CT examinations, and are not aware that common items such as metal zippers and wallets with magnetic buckles are metal objects that may interfere with CT scans. Even if they are asked, they may give incorrect answers due to insufficient knowledge, resulting in image artifacts, reduced image quality, interference with the scanning system, and may also cause accidental injury to patients, ultimately affecting the examination results, equipment life and patient safety.

[0004] To this end, we propose a dual-energy low-dose CT imaging and lesion analysis diagnostic device. Summary of the Invention

At the same time, the cylinder 2 73 is turned on. The cylinder 2 73 can drive the slide 74, the support sleeve 75 and the hollow frame 76 to move. The support bar 71 can be inserted into the hollow frame 76 to support the movable bed plate 4. When the movable bed plate 4 contacts the support sleeve 75, the hollow frame 76 moves on the inner wall of the support sleeve 75. The elastic rod 77 can play a role of buffering protection. After the hollow frame 76 is reset, the rubber positioning rod 78 also has a buffering protection function. In addition, during the scanning process, the shielding curtain 653, which is a lead curtain, can shield the side away from the CT scanning device 2, further reducing the damage of radiation to medical staff in the area.
