@heavyphil my experience with the Meridian was that I was in and out in about 20 minutes. There were 3 people operating the machine and monitoring the treatment, the RO, a physicist and a dosimitrist. This accounts for more labor cost but the Mirage randomized trial showed a significant difference in toxicity and side effect results between MRI guided and non mri guided radiation. So much so that there were quite a few institutions spending millions to buy both the MRIdian and now the Elekta.
