I understand human, training and software error factors but it would seem to me that routinely using a Phantom to test and calibrate the IMRT output, dose distribution and targeting accuracy should be a no brainer standard requirement.

I would think at least the NCI and ACS would have made it a requirement for designation and/or accreditation as an approved Cancer Center.

I looked for an online copy of the ACS Commission-on-Cancer standards for accreditation, but haven't yet found them (they seem to be for sale for $30!)
