Hi Jun,

I found something might be wrong in your code,

SUV=(double(Img)+RescaleIntercept ) RescaleSlopeSUVbwScaleFactor should be: SUV=(double(Img) RescaleSlope+RescaleIntercept )SUVbwScaleFactor

according to your reference or the link below https://blog.kitware.com/dicom-rescale-intercept-rescale-slope-and-itk/

Sorry for the late response. This code is written many years ago. I got chance to revisit recently as someone asked similar question. There might be some errors in it, I was a student at that time. But I recalled the calculated SUV was compared with the values calculated on radiologists' workstation (GE machine, if my memory isn't wrong). Feel free to contribute your code if you're willing to. I'll review before merging into main.
