Notes:
Computerized X-ray microtomography (micro CT) is a powerful technique for imagingand quantification in biomedical materials research. Mapping of various tissue/implants in3-dimension, which is not achievable with traditional histological slices, is particularly desirable inex-vivo implant analysis. However, due to a variety of artifacts during image formation, especiallythe blurred interfaces due to the machine contrast transfer function and the partial volume effect,quantification based on traditional histograms is not accurate. In this work we propose a new2-dimensional histogram and its application in the analysis of micro CT data of ex-vivo implants,which significantly improve the clarity of the definition of different phases and drastically reducedthe artifacts of segmentation compared to conventional methods
