Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a flat-panel detector fixing and adjusting device. Background Art

[0002] In the past decade, medical technology has made significant breakthroughs, one of which is the rise of image-guided radiation therapy (IGRT). This innovative technology marks a new era in modern radiotherapy and has been widely recognized and applied around the world. IGRT combines cutting-edge imaging equipment with image processing technology to achieve high-precision positioning of the patient's treatment area before treatment and real-time tracking during treatment, thereby significantly improving the accuracy of radiotherapy. This method ensures that the treatment area receives sufficient irradiation while minimizing potential damage to surrounding normal tissues and key organs, thereby optimizing the treatment effect. IGRT has undoubtedly laid a solid foundation for modern precision radiotherapy technology.

[0003] The IGPS image-guided radiotherapy positioning system, as a way to implement IGRT technology, uses advanced kV-level X-ray stereo imaging technology. The system controls two sets of X-ray imaging units symmetrically installed at the positioning center through software, and can simultaneously obtain X-ray projection images in two different directions. The system uses the image features of the patient's anatomical structure to perform precise position verification. When working in conjunction with radiotherapy equipment, the IGPS system can effectively detect and correct the patient's positioning errors, ensuring extremely high accuracy in the final positioning.
