IAEA-TCDOC-1540 Flashcards
type test vs site test
type is by the manufacturer
site is acceptance test
standard as basis for designing tests
IEC 62083
examples of type tests
-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
does each algorithm need to be tested separately?
yes
but only test relevant beam energies
examples of site tests
-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
tolerance for external beam calculation accuracy
2-5% depending on complexity
3 types of evaluation for measurements
-% 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)
what does doc provide?
test cases to test your TPS against
What is TEC DOC 1540 on?
specification and acceptance testing of radiotherapy TPS
