Eliminating Daily Shifts, Tattoos, and Skin Marks: Streamlining Isocenter Localization With Treatment Plan Embedded Couch Values for External Beam Radiation Therapy

ConclusionWe minimized near-miss incidents by using limited simulation user origins, converting user origin-to-isocenter shifts to absolute couch parameters, and enforcing restrictive tolerance tables to limit delivery parameter changes, coupled with surface guidance and quality assurance tools. This technique can be applied across institutions, age ranges, and tumor types and with or without surface guidance. This workflow has removed a common treatment setup error and the need for skin marks.
