The following report was sent from the State of
Pennsylvania via facsimile:
During the patient's treatment, it was determined that the wrong side of the patient's head was being treated [using a gamma knife]. The patient treatment was halted at 47.40 minutes out of the prescribed 55.63 minutes. The prescribed dose was 42.5 Gy to the 50% isodose line. Patient received 34.5 Gy to the 50% isodose.
PA DEP [The Pennsylvania Department] Bureau of Radiation Protection was notified in writing, dated July 29, 2009. Their suggestion for improvement is while all treatment team members are present during a 'time out' procedure, to have the patient state the side of his/her lesion or treatment and place an imaging marker to designate the treatment side.
The State [of Pennsylvania] will continue to keep NRC informed of the status of the investigation.

Based on our inspection and follow-up with the licensee, it was determined that, although the initial written directive was prepared in error, all radiation treatments received by the patient were, in fact, delivered in accordance with a written directive. However, the licensee has taken corrective actions to avoid a similar event occurring in the future.
Notified R1DO (White) and FSME EO (Suber).
