摘要
目的构建高分辨率中国男性数字人0.2mm断层间距图像数据集。方法取捐献健康男性遗体,经颈动脉红色灌注、低温冷冻定型、专用包埋模具垂直包埋、一次装夹连续等间距铣削、PhaseOneH25数码相机采集连续断层数据以构建数据集。结果共获得9320个RAW格式断层图像数据,分辨率为4080×5440象素,RAW格式单层数据量为27.5M,RAW格式总数据量为260G。结论高分辨率中国数字人男性数据集由于采用了2200万象素的高分辩率数码相机,断层上如血管、脂肪、软骨和骨骼等组织的边界清晰。并可用随机软件对图像的色彩、曝光量以及断层感兴趣区域进行重新处理。
Objective To establish high resolution image dataset of Chinese digital human male with a 0.2 mm interval section. Methods A Chinese male cadaver was perfused with red glutin through carotid and fixing the shape by frozen, then embedded in a special mould with a erectly position. The embedding block was clamped only once and milled continually. The dataset was established by the images, which were all collected by the PhaseOne H25 digital camera. Results Totally we got 9 320 section images by RAW format with a resolution of 4 080×5 440 pixels and per section image size is 27.5 M.The size of Chinses digital Human Male database with RAW format is 260 G. Conclusions The high resolution image dataset of Chinese digital human male is the first high resolution image dataset among all of the known datasets. Due to used the high resolution digital camera with 22 million pixes, the organic borderline and the tissue ,for example vascular,adipose,cartilage and bone etc,are very definitude.lt is very easy with the PheseOne software,to redispose the color and exposure of the section photo and the part of the image wich is interested in an analysis.
