You are treating a rectal patient on a Varian 2300 linear accelerator with a calculated SSD of 100 cm. Your patient’s AP/PA separation is 36 cm and his lateral separations are 42 cm. The tumor is located 19 cm deep from his anterior surface. The doctor has written a prescription for 28 fractions to a dose of 5040 cGy and a prescription for a boost of 3 fractions to a dose of 540 cGy. The daily monitor units for the AP portal are 58, RT lateral portal 73 and the LT lateral portal 78. Your patient is beginning his treatment on Thursday 12/1/2019.
