ABSTRACT:
A radiation phantom comprising a solid opaque housing having an inner chamber is provided within which a test pattern for quantifying image quality, and at least one dosimeter for simultaneously measuring radiation dosage are randomly disposed. A tamper proof means is connected to the opaque housing such that the test pattern and the at least one dosimeter are unviewable and unaccessible within the chamber. Thus, the test pattern and the at least one dosimeter are "interlocked" within the radiation phantom housing such that the radiation phantom can be employed to accurately evaluate off-site a radiation machine's imaging of the radiation phantom without requiring the presence of an independent qualified technician on-site during irradiation of the phantom.
