Can anyone explain why people use different CT values for the bolus we added for making flash? I have noticed some are using 0, while others use -500 or -200. What is your practice, and what are the pitfalls of using incorrect values? I observed that -500 provides a very stable dose Calculation value from optimisation to the final dose calculation.

Is anyone using Mobius3D in your clinical practice effectively? Please ping me. We didn’t receive enough training for implementation and use of this tool. We are trying to figure out how to evaluate it case by case. We observe failure in a 3% 3 mm 95% pass rate for chest wall targets like scf. If it’s failing, is it because we are not using it correctly or do different criteria need to be applied?
