Previous work showed that the scattered RF-fields created by dielectric pads and medical implants can quickly be calculated. The method requires an extensive offline calculation stage and a lot of memory. We propose an extension to the method that removes these two problems by using a volume integral equation solver. This allows us to do the entire calculation on a GPU for more acceleration. The resulting scattered electric fields have a maximum difference of 3.2% with respect to FDTD, while currently being a 106 times faster. Eventually, we want to use this method for patient-specific implant RF-safety assessment.
