Following a CT simulation, the therapist has saved two setup photographs, recorded skin marks, written set-up instructions, and a note describing how the patient's wearable electronic device was handled. A colleague will build the plan from this record tomorrow morning. Which verification confirms that the simulation documentation agrees with itself before planning begins?

The simulation record is the bridge between the scanned position and every future fraction, so its elements function as one description of a single setup: the marks and photographs document external geometry, the set-up instructions tell the next therapist which accessories and body position to rebuild, and the device note records how the wearable electronic device was handled in accordance with applicable guidance and departmental policy. Verification therefore means comparing each element with the others and with the planning scan, because a photograph taken before the marks were placed, or a sheet listing different supports, could send the daily setup somewhere the plan never allowed for. Checking only that the instruction sheet is complete and signed documents paperwork without proving it matches the images. Storing both photographs and confirming visible skin marks covers geometry but leaves the written instructions and device handling unchecked. Recording the device model and scan date and confirming image transfer verifies metadata and file movement, not how the patient was positioned. Exam caveat: required elements such as photograph retention and signatures vary by institution, so know your department's policy. Practical check: before you sign off, compare marks, photographs, instructions and the device note against the planning scan and confirm they tell one story.
