3. Product Overview
In general, NumaLink-3.0 discovers nuclear medicine image files in one OEM format that are placed in a
configured input directory, and translates them to image files in another OEM format in a configured
output directory. While performing this translation, it makes use of various directories in a work directory
tree. This flow is shown in Figure 4.

Tree
Input files are removed from the input directory as they are processed. Input files are not deleted
immediately; instead, they are moved to one of the following directories in the work directory tree:
Directory
Use
<work-directory>\cache
All files that have been translated successfully
<work-directory>\trash
All files that could not be translated successfully
<work-directory>\staging
Any files that are considered part of an incomplete translation set (for
example, if GSPECT studies are in separate time bin files and one of
the bins is missing; files in the staging directory are combined with files
that subsequently appear in the input directory, in the hope that at
incomplete set will eventually become complete and translatable)
Other directories in the work directory tree are:
Directory
Use
<work-directory>\intm_1
Temporary storage for intermediate format dumps before customization
<work-directory>\intm_2
Temporary storage for intermediate format dumps after customization
<work-directory>\nifimg
Temporary storage for pixel data
