WK1 | Functional check of couch motion and brakes (where applicable) |
WK2 | Functional check of unit motions and motion stops |
WK3 | Functional check of interlocks for added filters, correct placement of filters, and the matching of filters with kVp value |
WK4 | Quantitative dosimetric test: output reproducibility test for all energies. This test can be limited to the energies used clinically on the condition that any additional energies cannot be chosen at any time (by removing the corresponding filters from the treatment room, for example) |
