1.      A patient is treated on the 6-MV treatment unit at an extended distance of 124 cm. The collimator setting is 18 x 18 cm and the field size on the patient’s skin is 22 x 22 cm. The prescription states that a dose of 4700 cGy is to be delivered to a depth of 7 cm in 10 fractions with a single posterior treatment field arrangement. Calculate the MU setting.

What is the depth of maximum dose for a 10 MV beam?

1.      If a patient is to be treated at 133 cm SSD on a linear accelerator and the treatment field size is 27 cm x 37 cm at this extended distance, what would the required collimator setting be?
