AB  - OBJECTIVE: Our goal is to design and validate a simple apparatus for the safety 
      assessments of magnetically induced torques by four active implantable medical 
      devices (AIMDs) in 1.5 T and 3.0 T magnetic resonance imaging (MRI) environments. 
      MATERIALS AND METHODS: A simple apparatus was designed to measure the 
      magnetically induced torque. Before testing the apparatus, its effectiveness was 
      first evaluated with a commercially available weights. The torque values of the 
      four AIMDs, namely implantable cardioverter defibrillator (ICD), pacemaker, bone 
      conduction implant, and cochlear implant, under 1.5 T and 3.0 T MRI environments 
      were measured and compared with established international standard. RESULTS: The 
      ICD, pacemaker, bone conduction implant, and cochlear implant had average torques 
      of 1.405, 0.255, 9.460, and 5.490 N.cm under 1.5 T MRI and 2.950, 0.668, 14.618, 
      and 11.484 N.cm under 3.0 T MRI, respectively. DISCUSSION: The apparatus 
      developed in this study was verified to be feasible for measuring magnetically 
      induced torques, with tests on four types of AIMDs under 1.5 T and 3.0 T MRI 
      environments. Although the designed structure is simple, the apparatus was shown 
      to measure torque values of AIMDs under MRI accurately.
