Dose profile: a) measured dose profile of the original plan with and without Dolphin (X-direction with Dolphin: black line, X-direction without Dolphin: red line, Y-direction with Dolphin: green line, and Y-direction without Dolphin: blue line) and b) dose distribution normalized by the transmission factor (TF) without Dolphin measurement (X-direction without Dolphin: green line, X-direction of the normalized dose: cyan line, Y-direction without Dolphin: blue line, and Y-direction of normalized dose: magenta line) (measurement value: calibration unit (CU))
