I can promise you that Minesh's reasons for departure had little if anything to do with disclosures and COIs.
My disclosure in this situation is that Minesh is a friend, and foremost among all of my mentors. If he has a fault in this situation, it is that he's so genuinely excited by the science of what he's doing that he fails to consider how his relationship with TomoTherapy may color the way others view his opinions, and he probably should have remained silent rather than air his (legitimate) critique of a different platform, thus subjecting himself to these accusations. It's easy and understandable in this day and age how those who don't know the man will default to the more cynical view, that he is just a shill for Tomo. If you know him, or have read any of his manuscripts dealing with Tomo (I think I've read most of them), his work is no more advertisement for Tomo than Adler's is for CyberKnife, Kondziolka's for Gamma Knife, or Slater's for proton therapy.
A question for the "pure" academicians who are now falling over themselves in anti-industry self-flagellation (and probably don't read this board, so nobody take this personally): are these guys NOT supposed to publish manuscripts that provide a validation for the continued adoption of these technologies? In all the cases I noted above, the investigators' focus is on the technology, not the tool. The problem is that platforms such as Tomo and CyberKnife are unique in their delivery, thus making the technique and the tool inseparable.
Incidentally, Eli was pretty vocal about jhis problems with wider adoption of proton therapy during Eric Hall's talk at ASTRO 2006. He's been curiously silent on the subject since Penn's proton center opened. OMG, is that Ivory Tower really off-white? The VMAT/Tomo dispute would probably have been more deftly handled by John Stewart.
Whatever faults you may perceive in him, you will not find a nicer or smarter guy in the field than Minesh Mehta. That is saying a lot, but I stand by it. Northwestern is lucky to have him, and it is certainly Wisconsin's loss. And Kaushik, this isn't directed at you or GFunk or anyone else. I just happened to have a more personal perspective, and a bit of a rant, and wanted to share both.
