A patient’s thickness is measured and found to be 27 cm anterior to posterior and 32 cm laterally. If isocenter is to be placed midline and midplane, what should the AP and right lateral SSD read?

1.      A patient is treated on the 6-MV linear accelerator at 100 cm SSD. The collimator setting is 13 x 13 cm. The MLC reduces the treated area to a 9 x 9 cm EFS. The prescription states that a dose of 6500 cGy is to be delivered to a depth of 14 cm in 25 fractions using an AP/PA treatment field arrangement. The patient’s central axis separation is 28 cm. The spinal cord lies 5.0 cm beneath the posterior skin surface. Calculate the total Dmax dose and the cord dose.

What treatment(s) has the treatment time set in minutes? Select all that apply. 

1.      A patient is being treated with craniospinal axis radiation therapy. If the cranial field has a total length of 24 cm and is treated at 100 SSD and the spinal field is 16 cm in length and is also to be treated at 100 SSD calculate the skin gap if the fields are to converge at a depth of 8 cm.
