Test 2: Dose rate and gantry speed
 Dose [MU] = dose rate [MU/min] *arc length [o ] *(1 / gantry speed) [s/o ] *
1/60 [min/s]
 Dose rate 105 MU/min 210 MU/min 600MU/min
 Arc length 82.5 o 41.25o 13.3 o
 G speed 4.8o/s 4.8o/s 4.4o/s
1/60 min/s 1/60 min/s 1/60 min/s
 Dose = 30 MU = 30 MU = 30 MU
