I had the Varian IMRT at one facility, most likely the same at two other locations, not sure of the models though, and looks the same as the Trilogy, but may have done "Rapid Arc" too, which dosage time is accelerated as mentioned, and they may do IGRT also, not sure. Mine, point and shoot, some continuous, took about 17 minutes for 17 zaps, done bilaterally, and left side received the most, 9, and longer time.

My last IMRT a year ago, was 6 zaps, and the techs had to come in and turn the whole table for the last two shots to be in a 3 o'clock position.
