Abstract
A probe 1, for use with magnetic resonance imaging apparatus, which is designed to be inserted into and removed from a patient and which comprises a former 2 upon which an r.f. coil 3 is mounted is characterised in that the former also carries at least one transducer or sensor 6-9 by which the targeting of energy relating to an interventional procedure to an area in the vicinity of the transducer may be controlled both as to position and strength.
Claims8
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.
