Abstract: A method of determining the position of an induction-susceptive device inside an anatomical body part, comprises the following steps: a) emitting, towards the anatomical body part and from an electromagnetic emitter device, an oscillating electromagnetic field having a predetermined first field strength; b) acquiring, by using an electromagnetic detector device, an electromagnetic detection signal describing a second field strength which corresponds to the field strength of the electromagnetic field in the proximity of the anatomical body part; c) determining, based on comparing the first field strength and the second field strength, whether the second field strength differs from the first field strength, and d) if the second field strength differs from the first field strength, issuing a corresponding position indicating signal from an indication device, which position indicating signal indicates the presence of the induction-susceptible device.

Abstract: A surgical drape includes an impervious section having absorbing properties, an incision section including an incise foil, and a transparent section that is sized such that it allows a user to visually observe, through the surgical drape for registration purposes, a substantial part of a patient that is covered by the surgical drape. A method of registering a patient's body part with a pre-acquired image dataset of the body part is provided including providing a surgical drape including the impervious, the incision, and the transparent sections, covering the patient's body part with the surgical drape so as to provide a sterile workplace separated from an unsterile area by the surgical drape, using the transparent section of the surgical drape to visually identify the patient's body part covered by the surgical drape, and approaching and registering the patient's body part with a registration instrument such as for example a pointer instrument.
