IAEA-TCDOC-1540

Question 1

type test vs site test

Answer 1

type is by the manufacturer
site is acceptance test

Question 2

standard as basis for designing tests

Answer 2

IEC 62083

Question 3

examples of type tests

Answer 3

-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

Question 4

does each algorithm need to be tested separately?

Answer 4

yes

but only test relevant beam energies

Question 5

examples of site tests

Answer 5

-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

Question 6

tolerance for external beam calculation accuracy

Answer 6

2-5% depending on complexity

Question 7

3 types of evaluation for measurements

Answer 7

-% 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)

Question 8

what does doc provide?

Answer 8

test cases to test your TPS against

Question 9

What is TEC DOC 1540 on?

Answer 9

specification and acceptance testing of radiotherapy TPS
