A simple method for indirectly verifying noncoplanar treatment fields in radiotherapy.
The use of a vertex field can be a practical technique for treatment of pituitary and brain tumors. This approach may be underutilized, primarily because of the difficulty in documenting noncoplanar treatment fields. This paper describes a method for documenting vertex treatment fields by inference using portal films. This method is relatively simple to implement, yet yields accurate results.
