[Oradlist] Another NCRP question

[Moore, William]

Hi everyone,
We were having a review of NCRP 145 with our residents and noticed that
the maximum kVp for dental x-ray machines is limited to 100 kVp.  Many
of the current cone beam CT machines fall outside this range.  They
would therefore be classified as medical devices as I understand it and
fall under state regulations for such devices (ie. Medical tech vs
dental tech, physician oversight vs. dentist)  Am I interpreting this
wrong?  Is this a problem or can dentists use CT machines in their
office in your states? (not just order exams, but use and own)
