Perform the following calculations, using the CalculationBook_Complete in the Extra folder to look for values of certain parameters.
SSD Setup Technique
- A patient is simulated with a 10 x 10 cm treatment field, set up at 110 cm SSD to the patient skin. Rx: Treat 200 cGy / fx times 10 fx to 20 Gy Treatment depth = 5 cm
Energy = 6 MV photons 30 degree wedge used a) Calibrated Output for a 10x10 field b) Equivalent square of open field at 100 cm c) Collimator Scatter SC
d) Equivalent square of field on skin e) Phantom Scatter SP f) Treatment depth
g) Percent Depth Dose
h) Mayneord (F) factor
i) Modifying factors
j) Inverse Square (calibration factor)
k) Given Dose (dose to dmax per fraction)
l) MU If a point is at the same depth but 3 cm away from the central axis, and the physician what this new point to get the tumor dose of 200 cGy/fx
j) Off axis ratio
k) Wedge Off axis ratio
l) new MU
