研究目的: |
本研究拟通过人工智能深度学习的方法,构建前入路坐骨神经区域超声图像自动识别与分割模型。通过收集拟接受前入路坐骨神经阻滞患者的常规超声图像资料,并由有经验的麻醉医师对前入路坐骨神经及相关解剖结构进行人工标注,建立标准化超声图像数据库。在此基础上,采用深度学习模型对前入路坐骨神经区域进行自动识别与像素级分割,评价模型对目标区域的识别准确性和分割性能。本研究旨在探索人工智能辅助识别前入路坐骨神经区域的可行性,以期为临床神经阻滞工作提供新思路,并为人工智能应用于超声引导区域麻醉提供理论基础。 |

Objectives of Study: |
This study intends to construct an automatic recognition and segmentation model for the anterior approach sciatic nerve region in ultrasound images using artificial intelligence deep learning methods. By collecting routine ultrasound images of patients scheduled to receive anterior approach sciatic nerve blocks, and having experienced anesthesiologists manually annotate the anterior approach sciatic nerve and related anatomical structures, a standardized ultrasound image database will be established. On this basis, a deep learning model will be used for automatic recognition and pixel-level segmentation of the anterior approach sciatic nerve region, evaluating the model's accuracy in identifying the target area and its segmentation performance. This study aims to explore the feasibility of artificial intelligence-assisted identification of the anterior approach sciatic nerve region, in order to provide new ideas for clinical nerve block procedures and to provide a theoretical basis for the application of artificial intelligence in ultrasound-guided regional anesthesia. |
