Three-dimensional reconstructions from sets of CT data

There are considerable differences in the quality of three-dimensional displays and the amount of time needed for the appropriate mathematical procedures. The various systems available in this field are therefore surveyed and discussed in the following report. Those are the conclusions drawn: In clinical routine, simple 3D reconstructions of skeletal sections can best be prepared using a CT scanner and the pertaining 3D software. If more detailed information is to be obtained from such skeletal reconstructions, it appears better to resort to a specified image processing system. Colour-coded differentiated 3D images of vessels and soft tissues and automatically calculated volume data are solely provided by image processing systems especially developed for this purpose. The Kontron unit as an open system offers the advantage of unconventional approaches to three-dimensional data acquisition, but requires some knowledge of programming. (orig./MG)
