TABLE V.

Example checklist for preparation of patient data set for treatment planning suggested by failure modes in steps 18–21, 34, 45, 37, and 49–79 of Appendix C1 (Ref. 141).

Image datasets input into the planning process are checked for correct dataset choice (correct study of the correct patient), documentation, quality, etc.

Documentation of isocenter coordinates, measurements, patient positioning, etc. from the simulator is provided

Images verified for correct orientation

For image registration cases: Primary and secondary datasets (for registration) selected, achieved registration accuracy noted

Deviations or compromises in the registration are noted

Organs at risk are contoured according to departmental guidelines

Correctness of all 3-D representations (voxel descriptions, surfaces, etc.) is verified

Expansion of GTV to CTV follows site-specific protocols; automated margins worked correctly; variations noted

Expansion of CTV to PTV follows site-specific protocol; automated margins worked properly; variations noted

Boolean structure checks: Input to structures checked, regions created visually reviewed

Image artifacts (e.g., contrast, metal) corrected per department protocols

Patient support devices (e.g., immobilization, skin markers, couches) are correctly included or excluded

Treatment planning instructions are clear and unambiguous

Preliminary prescription written

Optimization goals and limits are specified, and applicable departmental or other protocols are used

Special instructions are written as in the department policy

Initial directive includes statement of previous treatment, review of previous treatments requested; the prescription accounts for any previous treatments
