Fully automated Tier 3 analysis of radio frequency (RF)-induced local power deposition at the electrodes of implantable devices for millions of excitations. IMAnalytics and MRIxViP are qualified by the FDA for MRI safety evaluations.

Contents	IMAnalytics is a novel software platform solution for the comprehensive safety evaluation of implantable devices. The module is designed to characterize the RF-induced heating at the distal electrodes of implantable devices, as well as the voltage at the lead terminals of the pulse generator, using the Tier 3 approach as defined in ISO 10974, and to extract the RF-induced E-field in a region of interest for use in the Tier 2 approach of ISO 10974, or for scaling of ASTM F2182 phantom measurements.
Applications	MR-safety with respect to RF-induced heating of structures such as leads for cardiac pacing/sensing, implantable cardioverter defibrillator (ICD), spinal cord stimulation (SCS), and deep-brain stimulation (DBS) systems.
Characteristics	Fully compatible with the exposure field libraries MRIxViP of the IT’IS Foundation. Preprocessing of terabytes of electromagnetic (EM) field data from many combinations of birdcage types, anatomies, landmark positions and implant routing paths. Direct input of the transfer function of the implanted device from piX system. Different polarizations and exposure conditions by sweeping through many independent excitation settings of the I and Q channels. Efficient evaluation of millions of exposure scenarios and extraction of relevant statistical data on deposited power. Evaluation of deposited power or induced voltage at different operating modes (normal, first level controlled). Different limits defined in terms of whole-body specific absorption rate (SAR), partial-body SAR, head SAR or B1 field values.
