Workflow

• “Dry run”: Preliminary study to optimize the workflow in a clinical situation and assess tracking accuracy.

Acquisition of kV fluoro sequence 20s and IR marker motion

Detection Visicoil and Building correlation model (IR vs internal motion)

Gimbals tracking (IR marker driven)

Patient Positioning (X-ray, CBCT)

Monitoring kV imaging (0.2 Hz -1 Hz)

• Simulation performed on 5 patients treated with ITV ! Evaluating tracking errors and defining appropriate margins ! Workflow efficiency and training ! Optimizing imaging dose
