AGREEMENT STATE REPORT - MEDICAL EVENT
The following information was provided by the New Jersey Department of Environmental Protection (NJDEP) via email:
"The licensee reported that during a treatment with an Elekta Leksell Gamma Knife Icon unit [on 5/18/2026], the unit halted treatment due to a collision error twice during the treatment. The licensee was able to clear the error the first time and continue with the treatment but were unable to do so the second time. This caused one of the treatment areas to only receive 7.9 Gy, compared to a planned dose of 21 Gy.
"After the licensee investigated, they believed the patient's blanket was bumping into the collimator cap, causing the collision errors. They have since tested the unit and, since it passed all testing, placed it back in service."
State Event Report ID number: TBD
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
