Table 3.
The expected (static) and obtained (moving) mean dose for the tumour, heart and spinal cord of all simulation cases in both right (R) and left (L) lungs. The beam on time calculated by small animal radiotherapy-Plan is shown between brackets to the right of the simulation case number, this value could be used to calculate mean dose rates and rotation speeds
