Question 3: 3. For a given course of treatment, if a fraction is imported in one format (eg. from an ARIA database) and then a subsequent fraction is imported in a different format (e.g., DICOM), Aria will ensure that the number of fractions delivered matches the number of fractions in the treatment plan. |
