Scheme of DQA in TMI planning. (a) Scheme of DQA with the cheese phantom (b) Film alignment in the WB phantom, (c) ion chamber alignment in the WB phantom. The WB phantom was moved so that the three ion chambers were located at approximately (d) the upper humerus, (e) thoracic vertebrae and (f) pelvic bone in the dose verification, representing locations where bone marrow is abundant. These regions are also suitable for point dose measurement because of a high dose and low dose gradient.
