A dоctоr prescribes а nоn-isocentric treаtment to а patient's thoracic spine on a linear accelerator that is calibrated to 100 cm.  The patient is being treated in an AP/PA set up, where the treatment dose is prescribed to the depth of the spine, which is 3.7 cm from the posterior aspect of the patient. The total dose prescribed is 4000 cGy for 10 fractions.  The portal size for the AP is 5 cm x 12 cm and the portal for the PA is 5.3 cm x 11.7 cm. The patient AP/PA separation is 23.1 cm.  What would be the equivalent square for the PA portal when calculating the monitor unit for this portal?
