Level | Vehicle autonomy | PSQA autonomy definition | PSQA autonomy examples |
L0 | No automation. | No computer aided operations. | Point dose measurements for verification of electron or 3D plans using an ionization chamber or diode. |
L1 | Driver assistance. | Human operations with computer assistance. | Computer aided measurements using PSQA devices with significant human involvements. This is the current practice. |
L2 | Partial driving automation. | Automated operations of the departmental computers that allow open access to OS. | Manual operations on departmental computers are automated, e.g. plan preparation and export in the treatment planning system, patient open/close on the R&V system and plan export to LINAC for QA delivery… |
L3 | Conditional automation. | Automated operations of vendor computers that don’t allow open access to OS. | Manual operations on the VARIAN computer controlling the LINAC are automated, e.g. open/close patient plans, treatment parameters updates... |
L4 | High automation. | Automated operations of all devices except in-room detector/phantom setups. | Manual operations on the Varian control console (e.g. treatment preparation, beam on/off…) are automated. |
L5 | Fully automated driving. | Fully automated PSQA. | In-room detector/phantom setups are automated. |
