Due to a radiotherapy medical system software defect, when performing angular roll corrections followed by a repeat localization, the roll corrections applied in the initial localization scan are not carried through to treatment delivery leading to the treatment plan dose being delivered to the incorrect location, potentially a displacement of 5mm or higher, with a 10% to 20% underdose.

Due to incorrect software configuration that potentially allows more than two (2) fractions within a 12-hour period (fractionLimits) and could potentially lead to adverse events (toxicity).
