IMAnalytics V1.0Beta

Fully automated Tier 3 analysis of radio frequency (RF)-induced local power deposition at the electrodes of implantable devices for millions of excitations.

IMAnalytics Module: automated Tier 3 analysis of implants (PiX transfer functions) with user-defined parameter ranges (e.g., normalizations, coil dimensions, shimming angles, clinical routings, subsets of the patient population and landmarks).

Product description

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, using a variant of the Tier 3 approach as defined in ISO/TS 10974. It is tailored for elongated lead structures by making use of the transfer function method described in Annex K of the same technical specification.

 

Features

  • 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 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.

Application

  • 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.

Verification

  • Version 1.0 of IMAnalytics has been thoroughly verified. The documentation of which can soon be downloaded here.

Release

  • Beta Version 1.0 is now available. The fully validated Version 1.0 will be released on July 11, 2017.
