Positions of radiation isocenter and the couch rotation center established by Winston-Lutz and optical measurements

PURPOSE: To compare x-ray and optical imaging methods for measuring the relative position of radiation isocenter and couch rotation center. To show the impact of radiation isocenter size and target motion on the margins for target contours. METHODS: Winston-Lutz measurements are made using EPID imag...
