Sano..

Not sure if you get chance to read how Feldcamp algorithm works ....Reconstruction with less number of images in Feldkamp gives very poor quality ....

DVIS algorithm is not trying to find out common matching / intersection point in order to determine Z axis ....this is why it is computationally less expensive ....

Yes ....3d is the animation part ...which allows surgeon to view desired area of target in real time ....he can navigate (x, Y, Z) coordinate as per requirement.


Since fluoroscopic images are used to take 2d picture (X , Y coordinate ) ....there is nothing which stops to measure distance as well of pixel inside 2d picture ,this way even 3d base map can be updated continuously....


Sano: Most of these information came for a guy , who have spent 25 year in writing imaging S/W ....CT , Feldkamp , exact 3d construction algorithm ....He had worked with almost all the big medical imaging company .... Your comment are just baseless fact ...filled with desperate "basher instinct "

In the NSE letter reviewer never said the DVIS image quality is bad ....He is trying to compare algorithm with Fledcamp ...as as result he suspect that 36 picture can not give good image quality ....which is not true in DVIS context.

SANO (or anyone else that knows)

Do you know if it is possible through FOIA to receive previous correspondence from the FDA, including the requests for additional information?

I'd like to see how that information lines up with what we were told on other conference calls, particualrly the one where the CEO insisted it was only a "labeling issue." Given the fact of the NSE, it seems impossible that it was only a "labeling issue"

I'd be willing to spring for the information and would definitley post it when I received it. I'm particularly interested in the previous three correspondence letters from the FDA prior to the NSE as we were given very specific information on conferecne calls as to what the FDA was doing / saying at those times that all seems to fly in the face of the NSE.

Thanks in advance
