Campbell7, Physios are certainly capable of taking any advantage , should there be any , of x-rays scans etc. In Australia these normally would be reported on by a radiologist, whose professional opinion is reliable as a way to interpret these. In most cases I would rely on these reports to satisfy myself that no serious abnormalities were present. These include fracture, tumor and dislocation. Once these have been eliminated , the value of scans and x-rays diminishes rapidly as a means to understand a pain /dysfunction problem.
By all means take them , but don't be surprised if he/she seems to take little interest in them, beyond a scan of the report.
