Patient Arrives
Patient Escort In
Treatment
Patient Escort Out
Patient Arrives to Clinic and walks to waiting room. Based on Check-in time data from MosaiQ

Patient is escorted into treatment room by therapist. This is based on when the machine becomes available.
Patient assigned a treatment type (IMRT, 2D,3D, etc.) based on the machine's procedure mix. Time in treatment is determined by the probability distribution of time from the observational data.
When treatment is complete, 75% of patients leave the room by themselves and 25% of patients are escorted back to the waiting room by the therapist.
