Yes, if you already have TOR MAS phantom or similar. The TOR MAM is actually intended to perform a check by visual assessment, but of course this will not be a proper calibration of the scanner, that should be done with a proper calibration phantom.

I suggest that for proper calibration you buy the TOR MAS, that is much more standard. If you already have this, then you can go to the TOR MAM that will allow you to do complementary tests.
