-
- These programs process a set of slices images (scans) for one
- patient. It outputs two sets of files containing nine predefined
- views of bony surfaces. One set contains distance values and
- the other gradient values.
-
- The distance values are used as 3-D spatial topographic surface
- coordinate maps for geometrical analysis of the scanned object.
-
- The gradient values are used for rendering the surface maps on
- CRT displays for subjective viewing where perception of small
- surface details is important.

- This disk contains several CT scan slice data files
- to test the 3-D medical image reconstruction programs.
- If you have an IBM PC/AT or clone with 1.2 Mbyte floppy disks,
- we can offer sets of CT scan slices at a nominal charge. These
- are offered to help you experiment, develop, test and extend our work.
-
-
- The data file, "CTBILD.001", is a sample CT scan slice
- from a Siemens Somatom 2 CT scanner. It has a header
- block of 512 bytes, followed by 256 image lines. Each
- image line has 256 elements (pixels or voxels, if you
- prefer). Each pixel consists of 16 bits or 2 bytes. Of
- these, only the low order 11 bits contain gray scale
- data. The high order 5 bits (or in the case of other
- CT scanners, the high order 4 bits) may be ignored.
-
- The remaining CT scan data files, CTBILD.002 and CTBILD.003,
- contain different slices in the same individual (e.g. serial
- slices that, taken together, comprise a volume).
-
-
- If you are interested in other CT scan data sets in
- IBM PC/AT format, we may be able to help you. This is
- true when there is some academic purpose for the request.
- Contact the authors, as listed below, for more information
- on 3-D reconstruction imaging for the PC (and other
- platforms). Keep us informed on your progress, as we
- are most pleased to hear from you and share our work in
- biomedical image processing....
