[Insight-developers] Patented Code : suggested Topic for Frid ay's TCON

[Jay Udupa]

The type of arrangement described below by Bill (about placing code in 
Patented Directory with a contact name) is acceptable to Penn. The 
details pertaining to the FC patent are as follows.

Extraction of fuzzy object information in multidimensional images for 
quantifying MS lesions of the brain, US Patent # 5,812,691.
