Abstract :
A system for very-high-resolution (50 μm×50 μm×50 μm) 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
