Abstract: The disclosure relates to a method for evaluating electrically conductive objects comprising the steps of: (A) providing a computer-generated model of the object to be evaluated; (B) defining the one-dimensional representation of the object by means of a curve line, “center trajectory”, along the longitudinal axis of the object; (C) defining a number of radii, “blue disks”, along the center trajectory, said radii enclosing the three-dimensional geometry of the object; (D) generating a plurality of auxiliary trajectories using the radii defined in step (C), wherein the totality of the trajectories display the object with respect to its potential to absorb the applied tangential electric field, E-field; and (E) evaluating the tangential E-field at each of the trajectories generated in step (D) and the subsequent statistical preparation.

Abstract: A device and a method for testing the MR-safety of an implant (4). The device includes a phantom (1) that has a test volume filled with a medium (2), wherein the test volume receives the implant (4) to be tested, at least one RF transmitter (3) that emits radio-frequency electromagnetic radiation into the test volume. The device is used for detecting the heating of the implant (4) and/or of the medium (2) surrounding the implant.
Abstract: There is a need for devices and methods which allow for a risk-free and reliable test of the MR-safety of implants outside the human body. For this purpose, the invention proposes a device for testing the MR-safety of an implant (4), comprising a phantom (1) that has a test volume filled with a medium (2), wherein the test volume receives the implant (4) to be tested, at least one RF transmitter (3) that emits radio-frequency electromagnetic radiation into the test volume, and comprising means for detecting the heating of the implant (4) and/or of the medium (2) surrounding said implant. The invention furthermore relates to a method for testing the MR-safety of an implant (4), in which a device of this kind is used.
