Off-line verification of the day-to-day three-dimensional table position variation for radiation treatments of the head and neck region using an immobilization mask.
Variation in the table height position for 175 treatments of 167 patients was calculated as a measure for day-to-day set-up precision in 2063 treatment sessions and resulted in a median standard deviation of 1 mm. The median standard deviations of table longitudinal and lateral position were 3 and 5 mm, respectively.
