Patients with certain implanted devices have been restricted from MRI exams with the whole-body transmit coil due to concern of local heating. A novel compact 3T (C3T) MRI scanner is equipped with an RF coil of larger radius but similar length as a T/R head coil. The purpose of this work is to assess the RF B1 field and E-field of the C3T T/R coil. RF heating risk of head imaging on C3T for patients with implanted devices was evaluated and compared with a commercial T/R head coil.
