> That’s a lot of data really fast, so if you want this 3D scan of your body, yes, you do want as much data as fast as possible. 60 seconds sounds great compared to an MRI that’s going to take 15 minutes minimum & up to an hour or more.

This is deeply silly and nonsensical framing. You don't want "lots of data really fast", you want high-quality, diagnostically useful data. If the fastest way to generate that is via 15-minute MRIs, then that is vastly more ideal than a bullshit scan that takes seconds.
