Synthetic liver SBRT · LIVER_49
50 Gy in 5 fractions·contributed by 이강훈·2026-08-05
This CT was generated by a model. No patient was scanned.
The anatomy is synthetic and the structures come from the generator rather than from a clinician. Treat the Hounsfield units as plausible rather than measured: there is no scanner behind them and so no CT-to-density calibration of yours applies, and because the image has no real counterpart the error in them cannot be quantified at all. It is a planning exercise, and every plan here is scored against the same geometry — but nothing learned from this case is a statement about a real patient.
