Question about dose export

Jul 11, 2014 at 12:15 AM

I noticed after exporting dose and opening it up in matlab the values are dramatically different than what I see on the screen of my external beam planning. For example, most values near center of ptv will have a value close to 80 Gy but in the data that is exported I get a value of 904900. I used absolute dose. Is there anything wrong with Eclipse or is it because somehow they were summed to 1 cm^3 volume? I'm using v10.

Could you show your code for the "dose export"?

The Dose.GetVoxels() method gives raw voxel values in Int32. There is Dose.VoxelToDoseValue() to convert that to DoseValue.

You're using v10, so this is not directly related to ESAPI? And you exported a Dicom file? In the Dicom file there is a tag (3004, 000e) DoseGridScaling that you need to multiply with.
