Photoshop 3 for Macintosh, to ensure that the same hue was applied to each respective metatarsal cross section. The results were 57 images, saved as GIF format, with metatarsal cross sectional outlines filled with color. MT II, MT III, and MT IV were selected out of each image, and pasted into respective files. The new files had the same pixel dimensions as the originals, and the respective metatarsal images remained in the same position as in the original image. This meant the cross sections of the metatarsals would remain in the same relative position when the images were stacked for 3D reconstruction, and would maintain the same spatial relationships as the original bones. Images of individual rnetatarsal cross sections were also saved in GIF format. Sets of individual images for each metatarsat were then concatenated into three large files, containing data for al1 image slices of each respective metatarsal. These were saved as raw data fomat files, with names containing as much information as possible, to facilitate input for subsequent processing. For instance, the file containing red-filled outlines of the second metatarsal was called red-512x512x57.raw2, signtfying that there were 57 images each measuring 51 2 pixels square. 3. Slice spacing calculations and curve detection Once these collective image files were created, they required preparation for curve detedion and stacking software. A program written by Dr. Doug Phillips, volume-to-nuages, performed the necessary calculations and format
