According to the company's statement, the magnitude of the error of calculation of the dose depends on the transformation of the registry and may range from 0 to 100% of the correct dose value. We have identified two clinical scenarios in which the problem may impact patient care: 1. Multi-modal imaging prior to the first fraction, in which the secondary data sets are used in contour definition and dose assessment. 2. Pre-treatment image examinations and plan adjustment based on contour definition and dose evaluation in the secondary data set (pretreatment). The isodose line function, which is commonly used for dose assessments in conjunction with the dose assessment functions mentioned above, is not affected by this problem. The company also reports that the problem was discovered during the introduction of a new treatment protocol at a client center on March 18, 2015. The client perceived the problem directly when comparing the DVH values ​​with the isodose lines during the evaluation plan. ##### Update of the field action: UPDATED ON 11/03/2017, the company presented the completion report of the field action, with sending of necessary evidences and corrective actions.
