A patient is prescribed to have two 15 x 15 cm treatment portals, which are equally weighted, parallel opposed lateral fields, treated to a dose of 350 cGy, using the source to axial technique and an 18 MV beam. The patient’s separations are 42 cm. The linear accelerator has a reference output of 1.132 cGy/minute in air at isocenter. The collimator scatter factor is 1.036. The fields have a tissue air ratio of 0.752 and tissue maximum ratio of 0.685. Each beam will have a 45-degree wedge with a wedge transmission factor of 65.6%. Calculate the MU for one of the beams.
