Remcom announced an update to its XFdtd® 3D Electromagnetic Simulation Software with new features for the biomedical industry. The central biomedical addition in the release is an enhanced Biological Thermal Sensor, exclusive to the Bio-Pro version of the software. XFdtd Bio-Pro is a specialty version of XFdtd, developed to calculate the biological effects of electromagnetic fields. In addition, MATLAB® export functionality has been added to all versions to expand engineers’ post-processing options. The Biological Thermal Sensor allows metals and other non-biological objects to be included in temperature rise computations. The calculations consider the effects of conductive heat transfer between thermally connected materials, blood perfusion, metabolic processes, and general RF heating. The new sensor provides crucial data to engineers studying temperature effects of RF exposure. Analyses include therapeutic heating devices; MRI heating in patients, including effects of implants, probes, and electrodes; microwave thermal ablation; and implantable devices.
In addition to the thermal sensor, the new release includes MATLAB export functionality. All data available through XFdtd’s Result Browser can be exported to MATLAB and CSV formats. This enables full post-processing of data with MATLAB’s extensive mathematical and visualization capabilities. Exportable result types include rotating B+/- and SAR results, grid vertex locations and mesh material properties needed for custom SAR post-processing, and more. There are many additional usability enhancements in the release including PrOGrid Project Optimized Gridding™, a new capability that simplifies the process of optimizing both accuracy and runtime when creating grids.
About XFdtd and the Bio-Pro Version:
XFdtd Bio-Pro provides users with a bundled collection of important biomedical EM calculation capabilities such as Specific Absorption Rate (SAR) analysis, VariPose® Mesh Repositioning, and Hearing Aid Compatibility (HAC). Bio-EM analyses include imaging devices and MRI coil design and tuning, SAR and field analysis, implantable devices (pacemakers, diagnostic equipment), field exposure from radiating sources (cell phones and other antennas), human models and phantoms, and regulation/certification.
