Q

examples of type tests

A

-units in mm or cm but not both
-date display is clear
-protection against unauthorized use
-data limits- operation prevented if outside of limits
-correctness of data transfer
-saving and archiving
data
-operator has to be able to see pertinent data in the model
-cautionary message before deleting a model
-coordinate system is with relation to patient
-confirm assignment of images belong to the correct patient
-max limit of beams, sources etc. are specified
-state accuracy of algorithm
-report will indicate if treatment plan is incomplete

Q

examples of site tests

A

-subset of type tests
-protection against unauthorized use
-data limits
-correctness of data transfer
-coordinate system and scale
-if treatment plan is approved, have to unapprove it to make changes

Q

3 types of evaluation for measurements

A

-% error relative to measured dose (relative error)
-% error related to dose on axis at same depth (relative normalized error)
-% error related to dose in unblocked beam pt at the same depth as when the central axis is blocked (relative normalized error)
