Abstract

A system for very-high-resolution (50 mu m*50 mu m*50 mu m) three-dimensional tomography of small (1 cm*1 cm*1 cm) biological specimen is described. Two-dimensional planar X-ray views of the specimen are acquired by an image intensifier and digital camera system while the specimen is rotated through several hundred positions. The recorded data are processed to obtain spatially accurate estimates of the attenuation line integral and reconstructed using a cone-beam algorithm. Measurements obtained with this system are being used to study the structures found in bone biopsy specimens.<>

用于骨结构测量的x射线微断层扫描系统

描述了一种用于小型(1cm * 1cm * 1cm)生物标本的高分辨率(50 μ m*50 μ m*50 μ m)三维断层扫描系统。样品的二维平面x射线视图由图像增强器和数码相机系统获得，同时样品通过数百个位置旋转。对记录的数据进行处理以获得衰减线积分的空间精确估计，并使用锥束算法进行重建。使用该系统获得的测量结果被用于研究骨活检标本中的结构。
