yes, this is essentially a CT-gantry... of the 3rd generation...

both the x-ray source and the detector are spinning about the patient...

the x-ray beam is emitted from the source to the detector plate... because both spin the x-ray photons always strike the detector...

here's 3rd generation CT spinning up to max speed...

the detector in this video is not a flat detector... it is how i described the routine 3rd generation detector concave to the gantry. it is the thing that looks like there are 5 cooling fans on it with it in a position near the top of the gantry in the beginning...

now, in my opinion --- as a side note, the only real way your gonna achieve realtime 3d fluoro (fluoro by definition is realtime) is to have such a fluoro-gantry device.... i don't believe the medtronic o-arm is capable of becoming a full gantry with the stability that the DViS would have... and therefore don't believe it could ever obtain what the DViS does...

this is the genius behind dean...

as a side note:

it is not uncommon for heavily used CT machines to be on/spinning all the time and just emitting when necessary...

this is how dean described the fluoro apect of the DViS during the most recent CC... which is why i posted something like "this is as i would expect."

the beam/radiation is only used as necessary...
