The State provided the following information via facsimile:
Treatment delivered to two (2) of seven (7) lesions on a patient on 18 July 2005, were discovered to be 50 percent less dose than that prescribed. (15 Gy (Grey) per lesion prescribed; two lesions received only 7.5 Gy each) This was discovered [on 3 August 2005], during an internal audit of treatments, conducted by medical physicist not originally involved with treatment. To date the investigation does not identify a problem with the equipment or the dose programs involved in planning. Initial indicators point to a potential communication problem between the original medical physicist and oncologist. At this time the investigation is pending due to the unavailability of the medical physicist due to vacation. Resumption of the investigation is to commence on or about 9 August 2005 when persons involved have returned from vacation.
