CT scanning

I am exploring the idea of using a Computed Tomography scanner to
examine a painting before treatment.  The painting is by Sir A.J.
Munnings and it appears to have been painted over an old painting. I
have been offered the use of a CT scanning machine by a local
hospital radiology department.  Has anyone ever attempted CT
scanning of a painting before?  Was it useful?  Are the exposure
times and strengths to the X ray wavelengths used more damaging for
an oil painting?
