What do you do for physician approval of IGRT images?
Please respond as I am looking for as many responses as possible. At our institution, we are present for the first IGRT where we discuss alignment objectives with the therapists, and we view and approve all images prior to the next fraction. We also assure a physician is available for any questionable alignments while the patient is on the table.

Our philosophy is as above with the only difference being for CBCT one of the physicians always tries to be there at machine to approve films prior to treatment.
Discussing and explaining with the therapist the area of match for each individual case is part of the process.

We review kV igrt at the time of V sim prior to starting treatment as well as any port films at that time.
Otherwise, we review kVs after treatment unless there is a question. CBCT is always reviewed by a physician prior to treatment.

I don't see this issue as something that can be simplified to guidelines. I suggest the MD go to the machine for the first 5 fractions of CBCT to get a sense of 1. How well the SIM aligns to the treatment table set up (never perfect) 2. How well your plan has translated into a daily set up (e....
