By the end of 2006, two companies, No Lie MRI and Cephos, will bring fMRI's ability to detect deception to market. Both startups originated in the world of medical diagnostics. Cephos founder Steven Laken helped develop the first commercial DNA test for colorectal cancer. "FMRI lie detection is where DNA diagnostics were 10 or 15 years ago," he says. "The biggest challenge is that this is new to a lot of different groups of people. You have to get lawyers and district attorneys to understand this isn't a polygraph. I view it as no different than developing a diagnostic test."
