Fig. 6From: Development of a novel delivery quality assurance system based on simultaneous verification of dose distribution and binary multi-leaf collimator opening in helical tomotherapyRelationship between the scintillation light and exposure time in the measured values of the ionization chamber. The black line indicates the scintillation light (gantry stationary), the red line indicates the scintillation light (gantry rotating), and the blue line indicates the ionization chamber dosimeterBack to article page
