You are treating a lumbar spine metastasis from the patient’s lung cancer on an Elekta linear accelerator with a calculated SSD of 100 cm. The patient is able to lay prone. She begins treatment on Monday, May 24. The doctor has ordered 14 fractions to a total dose of 3500 cGy. The doctor orders that the patient be treated non-isocentrically. Her AP/PA separation is 36 cm. The spine lesion is 7 cm from her posterior aspect. May 31 is Memorial Day and the cancer center is closed, there will be no treatments that day. Your patient calls you on Tuesday 6/1 and tells you she cannot make it in for treatment because she went out of town for the Memorial Day weekend and could not get home. What is her elapsed day on 6/2?
