FastTracks is designed to open image sets that have been captured and stored by TrackWorks, and to provide a virtual microscope interface in which these can be examined. The real power and purpose of FastTracks, however, is the automatic fission track counting system that it contains. These image processing algorithms provide a radical new approach to the counting and measurement of fission tracks in natural minerals. The analysis and measurement of fission tracks with this system is now separated from the microscope and can be conducted on a computer anywhere. FastTracks changes the role of the operator from one of counting all of the tracks manually, to one of reviewing the automatic count results, and correcting these where necessary. The automated counting system and how to use it are described in chapter 8. FastTracks also includes the various track measurement tools that are found in TrackWorks, but in this case they are for use on the captured images.
