Biological Applications of Microtomography
Abstract
X-ray microtomography can be used to obtain, non-destructively, 3-dimensional information about biological structures at a resolution of a few microns. The information may be purely morphological, but if accurately monochromatic X-radiation is used, the results are in the form of the 3-dimensional distribution of the linear absorption coefficient.
The X-ray source used was a microfocus X-ray generator with a 100 pm source and molybdenum target. The transmitted X-ray intensity of the sample was measured with a high purity germanium detector which allows the measurements to be made with monochromatic radiation.This system was used to determine the quantitative distribution of X-ray absorption in a rat rib bone and elephant dentine (ivory).
