[Intl_DxMedPhys] EXT MSG Fwd: The New CMS Measure: Methods for Size-Adjusted Dose and Their Variabilities

[Jie Zhang]

Yes. We have also investigated global noise metrics and their potential
limitations in clinical applications. We are wrapping up our writing and
hope to share our results soon.

Thanks!
