I don't know of a way to do this easily from Horos. You can use the "Export ROI" plugin to export all pixel values as XML or CSV - but then you need to massage the data to create a histogram yourself.

I did add the capability to export a histogram to a CSV file to the IB Rad Tech plugin from Imaging Biometrics (https://www.imagingbiometrics.com). It also adds other capabilities (define number of bins, export to a JPEG file, export to a DICOM SC for the study, define colors for bins).

Dear Todd,

I am struggling with finding where to download the "Export ROI" plugin you are referring to. Could you please help me?

Best regards,

Normally you would be able to get the "Export ROI" plugin via the Horos Plugin Manager, but the connection to the horosproject.org site will be blocked by recent versions of macOS due to an expired certificate (see thread at https://groups.google.com/u/1/g/horos-project/c/FfPBHP8He_8/m/ijM0F6uGAAAJ). While the horosproject.org site seems to have a valid certificate, the www.horosproject.org/horos-content/version.xml and other links to files there does not.

The best solution is to reach out to Purview and have them resolve the issue so that the links to files under http://www.horosproject.org/horos-content resolve to a link that has a valid certificate.

Or you need to get the plugin another way. It could be compiled, signed, and installed yourself using the source code at:

You could also download the plugin directly from https://horosproject.org/horos-content/plugins/horos/ExportROIs/ExportROIs.horosplugin.zip but it is not signed so you will need to deal with installing it via another workaround.
