A teletherapy patient received a dose greater than 50% of the prescribed fractionated dose due to an improperly calculated dose delivery time. The medical physicist used a fractionated dose of 200 cGy instead of the prescribed dose of 100 cGy. This overexposure occurred during the first fraction to the patient. Before the second scheduled treatment, a different therapist questioned the long treatment time and brought the matter to the medical physicist. The physicist checked the calculations, discovered the error and cancelled the treatment for the day. The radiation oncologist anticipates no unusual acute or late effects from the delivered dose. The University of Iowa no longer is in possession of this device. It was de-sourced on November 16, 2005. | A teletherapy patient received a dose greater than 50% of the prescribed fractionated dose due to an improperly calculated dose delivery time.
