Microsurgical Aneurysm Clipping Surgery (MACS) Dataset with image-level aneurysm presence/absence annotations

We collected and present a microsurgical aneurysm clipping surgery (MACS) dataset comprising of 16 videos of MACS procedures with aneurysm presence/ absence annotations at frame-level (~350k frames) conducted by expert neurosurgeons. We extract frames at 5 fps and establish a dataset of 356,165 images. The MACS dataset is composed of FHD (1920x1080) surgical videos from the operative microscope of 16 patients during surgical repair of intracerebral aneurysms. The study was registered with the hospital’s (National Hospital for Neurology and Neurosurgery, UCLH NHS) local audit committee and data sharing was approved by the information governance lead. All patients provided written informed consent for their video to be collected for research. The MACS dataset was blindly reviewed by two senior vascular neurosurgeons in duplicate. Frames were classified as follows: Type-X : No aneurysm in microscope’s view, Type-Y : Aneurysm in microscope’s view (including both visible and clipped aneurysms), Type-Z: Frame excluded from analysis. <br>

本研究收集并公开了显微动脉瘤夹闭手术（microsurgical aneurysm clipping surgery, MACS）数据集，该数据集包含16段由神经外科专家完成的MACS手术操作视频，并在帧级别（约35万帧）标注了动脉瘤的存在与缺失情况。
我们以每秒5帧的速率提取视频帧，最终构建了包含356,165张图像的数据集。
该MACS数据集的视频均取自16例接受颅内动脉瘤修复手术患者的手术显微镜录制影像，分辨率为全高清（Full HD, FHD，1920×1080）。
本研究已在医院（英国国家神经病学与神经外科医院、伦敦大学学院医院国民保健服务体系，National Hospital for Neurology and Neurosurgery, UCLH NHS）本地审计委员会完成注册，数据共享方案亦获得信息治理负责人批准。
所有患者均签署了书面知情同意书，同意将其手术视频用于本项研究。
该MACS数据集已由两名资深血管神经外科医生进行双盲重复审核。
视频帧分为以下三类：X型：手术显微镜视野内无动脉瘤；Y型：手术显微镜视野内存在动脉瘤（包括可见动脉瘤及已夹闭动脉瘤）；Z型：需从分析中排除的帧。
