Phantom for simulating the electric loading in a magnetic resonance apparatus |
摘要 |
A phantom which simulates the electric load in a magnetic resonance apparatus includes a loop which can be inductively coupled to the RF coil of the MRI apparatus and which has a predetermined electric resistance. The phantom has a simple, rugged and light construction in that the loop includes a member having a shape that corresponds mainly to the shape of the RF coil and which is made of a solid material having a specific electric resistance and a thickness chosen so that the square resistance measured on a surface of the member is between predetermined limits. The member is preferably formed as a layer of an electric resistive material provided on an electrically insulating support having a suitably shaped surface.
