After CT simulation for an abdominal patient, a second therapist will run the daily treatments from the saved plan, and the scan plus setup photographs are already filed. Which detail must be written into the setup instructions to reproduce the position every day?
Select an answer to reveal the explanation.
Short Explanation
Photos show what the position looked like, but they don't tell the next therapist how to rebuild it. Your indexing note, the slot the device locks into and where the marks sit, helps make day two match day one. It's like a recipe that lists the oven setting, not just the finished dish.
Full Explanation
Daily treatments must be rebuilt from the simulation, and the setup instructions should specify where the immobilization device indexes to the table and where the patient's marks sit relative to it. Recording couch height and laser setup alone may describe the machine position at one session without defining how the device and marks relate to it. Listing the device alone identifies the accessory but does not say which slot it indexes into or where the marks land. Recording weight and contour tracks body size rather than specifying the geometry needed to reproduce the setup. Exam caveat: look for the item that fixes the relationship between patient, device, and couch, because hardware identity or room settings alone do not fully describe the setup. Practical check: before the patient leaves the table, read back the index position and mark relationship and confirm the photos show the setup.
