VisionGate Inc.

In early 2001, after leaviing his post as executive chairman of TriPath Imaging, Alan Nelson founded VisionGate Inc., which is focused on developing a test for lung cancer screening. The technology he designed directly measures and quantifies structural changes in chromatin indicative of early-stage lung cancer, and uses proprietary optical microscopy that enables 3-D analysis. The result, he believes, is the first effective clinical screening test for this almost always fatal disease.
