Zusammenfassung:	According to an aspect, there is provided a method of determining a location of a device on a surface of a body part of a subject that is treated by the device during a treatment operation. The device is for performing the treatment operation on the body part, and the device comprises one or more orientation sensors for measuring the orientation of the device in a reference frame of the device. The method comprises obtaining a three dimensional, 3D, representation of the body part, the 3D representation comprising normal vectors for respective positions on the surface of the body part; receiving a plurality of orientation measurements from the one or more orientation sensors representing orientation of the device during the treatment operation on the body part; processing the received orientation measurements to determine a sequence of orientations of the device during the treatment operation; and comparing the determined sequence of orientations of the device to the normal vectors and respective positions of the normal vectors to determine the location of the device on the surface of the body part during the treatment operation.
