Title: SYSTEM AND METHOD FOR DETECTING AN ASSYMETRICALLY POSITIONED INTERNAL OBJECT IN A BODY
Abstract:
The embodiments herein relate to a system for detecting an internal object (100) in a body (103). The system comprises at least one antenna pair comprising two antennas (105) which are adapted to be symmetrically positioned around the body (103) in relation to a line of symmetry (108). The system is adapted to transmit microwave signal(s) into the body (103) which are reflected and/or scattered from the internal object (103). The system is adapted to receive the reflected and/or scattered microwave signals, and to compare the received microwave signals at the symmetrically positioned antennas (105). The system is adapted to detect the internal object (100) or a change in an already detected internal object (100) when there is a difference between the received microwave signals at symmetric antenna pairs. The difference is related to the different dielectric properties between the internal object (100) and the body (103).
