Treatment planA summary of the treatment plan for CTV1 is shown to the right.
Note that large targets often require two fields per gantry angle because the length of the leaves on a Varian MLC limits the width of all IM fields to 14 cm. Two fields at a single gantry angle are treated side-by-side
Note that targets which project to a width less than 14 cm can be treated with one field.
Time to treat = 30-60 sec./field
