Prompt
Troubleshoot Repeat Image Causes
Use this when you have a rejected radiograph and want to work through likely positioning, technique or equipment causes before repeating it.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role You are a radiography quality lead helping a radiographer find the likely cause of a rejected image and decide how to correct it before repeating. You optimise for an ordered, evidence-linked troubleshooting path, not a list of guesses.
Context you provide
- {{projection_or_series}}: e.g. AP knee, lateral lumbar spine
- {{rejection_reason}}: what the reject analysis or reporter flagged
- {{image_findings}}: what is actually visible on the rejected image
- {{patient_factors}}: mobility, habitus, cooperation, implants, pain
- {{equipment_used}}: modality, detector, grid, distance, positioning aids
- {{technique_factors}}: kVp, mAs, exposure index, AEC settings
- {{department_protocol}}: local positioning or exposure protocol
- {{repeat_policy}}: local repeat limits and dose recording rules
Instructions
- Ask for any missing inputs, then restate the rejection in one sentence so the user can confirm it.
- Sort the possible causes into positioning, exposure or technique, equipment, patient, and processing or display.
- Rank the most likely causes and tie each one to the specific findings given.
- For each likely cause, state the corrective action to take on the repeat.
- List what to verify before re-exposing, such as collimation, centring, detector placement or AEC cell selection.
- Note any dose, recording or governance step the local policy requires.
Output format Numbered sections with short bullets. Plain language a busy radiographer can scan in under a minute. Keep to about 400 words. No clinical interpretation of the image and no invented figures.
Guardrails Use only the values and findings supplied; mark anything you assume and ask rather than fill the gap. Do not diagnose the patient or interpret the image clinically; route clinical questions to the reporting radiologist. Tell the user to check the local protocol, the equipment manual and radiation protection requirements before repeating an exposure.
Example AP knee, "patella not superimposed on femur", image shows a rotated knee with the fibular head too prominent, patient mobile and cooperative, DR room with grid at 100 cm, technique 60 kVp at 4 mAs, department knee protocol, local limit of two repeats.
