X射线断层扫描设备和基于人工智能的医学图像处理

摘要：Conventional CT and spectral CT technologies provide physicians with comprehensive imaging information. During surgery and radiotherapy, domestic O-arm CBCT equipment can navigate intraoperative procedures. Additionally, mobile and standing CT scans make imaging examinations more convenient and suitable for various scenarios. After CT image reconstruction, models such as the visual transformer, large language model, visual foundation model, visual language model, and video generation model demonstrate excellent performance in the classification, segmentation, and analysis of medical images. Humanoid robots can assist surgeons during operations. Finally, the hallucination and ethical problems in AI, along with potential mitigation and regulation solutions, are discussed.

常规CT和能谱CT技术为医生提供全面的影像信息，在手术和放疗过程中，国产O臂CBCT设备可实现术中导航，移动式和站立式CT扫描使影像检查更加便捷，适用于多种场景。CT图像重建后，视觉Transformer、大语言模型、视觉基础模型、视觉语言模型、视频生成模型等模型在医学图像的分类、分割和分析中表现出色，人形机器人可以辅助外科医生进行手术。最后，讨论了AI中的幻觉和伦理问题，以及潜在的缓解和监管解决方案。
