摘要 |
The present invention relates to an implant (115) fixable relative to a target area (117) within a living body (105), comprising a transmitter (7; 107; 207; 307) arranged to emit an electromagnetic signal, wherein said electromagnetic signal is adapted to propagate with a wavelength 2 in said living body (105) so that a phase difference of said electromagnetic signal in at least three positions, preferably four, separated by a known distance (b) is detectable by a receiver (9; 109; 209; 309) for tracking variations of a position (p) of the implant (115) relative to said receiver (9; 109; 209; 309). Further, the present invention relates to an apparatus (1; 101; 201; 301), a system and a method for tracking a position (p) of a transmitter (7; 107; 207; 307). Additionally, the invention relates to the use of such a method for treatment of a target area (117) in a living body (105) by means of a radiation therapy treatment arrangement (100). |
