Looking for open image sets for machine learning radiomics

Hi there!

I'm a research medical physicist working on some machine learning radiomics research and have run into a wall. I have a very small data set provided for me by my affiliated hospital, and it is just not enough to train the model for conclusive results.

I have asked for more data, however, it is unclear when they will be able to provide it. I understand the physicists/clinicians in the hospital need to sort through and anonymize the patient images and they have packed schedules as is.

I'm wondering if anyone here knows of an open image dataset I would be able to use to supplement my training set. I have looked through TCIA but would like to hear any suggestions you have!

I'm looking for lung CT images, preferably over the course of treatment. I'm specifically looking at radiation induced tissue damage, and that has been the hardest thing to find in open source image sets.

Thank you for any suggestions!
