The Determination of Virtual Source Position Using Poka-Yoke Concept to Minimize Mistakes for Scanning-Passive Scatter Beam in Carbon Ion Therapy

We developed a mistake-proofing technique (Poka-Yoke) capable of dealing with the virtual source position delivered by different carbon ion energies for scanning-passive scatter beam in carbon ion therapy. Despite a lot of methods that have been proposed for the determination of virtual source position for electron beam therapy in a linear accelerator and proton beams, none for heavy charged particles-like carbon ions have been investigated. The method can be also used for electron and the proton beams.
