Abstract:
A method of targeting a region of an interior anatomy of a patient for an interventional therapy procedure, the method comprising:inserting a probe which includes a magnetic resonance coil into a cavity of the patient adjacent the region of interior anatomy that is to be subject to the interventional therapy procedure;with the probe, generating a magnetic resonance image encompassing the region of interior anatomy and the probe such that the image depicts a location of the probe relative to the region of interior anatomy to be subject to the interventional therapy procedure;aiming a beam of radiation with a radiation level below a level which damages tissue along a trajectory through the internal anatomy which trajectory intersects the probe;determining whether the beam of radiation is striking radiation sensors mounted on the probe;adjusting the trajectory of the radiation beam until the trajectory intersects the sensor such that aiming the radiation beam is correlated with the magnetic resonance image.
