Abstract
A medical probe, including a flexible insertion tube having a distal end for insertion into a body cavity. An array of spatially separated coils is positioned within the distal end. A processor is configured to process respective signals generated by the coils in response to magnetic resonance of tissue in the body cavity, and to process the signals while applying a phase delay responsive to a separation between the coils so as to image the tissue.

A medical probe, comprising:
- a flexible insertion tube having a distal end for insertion into a body cavity;
- an array of spatially separated coils positioned within the distal end;
- and
- a processor, configured to process respective signals generated by the coils in response to magnetic resonance of tissue in the body cavity, and to process the signals while applying a phase delay responsive to a separation between the coils so as to image the tissue.
A medical probe, comprising:
- a flexible insertion tube having a distal end for insertion into a body cavity;
- a first array of spatially separated first planar coils positioned within the distal end, wherein respective planes of the first planar coils are parallel to a first plane;
- a second array of spatially separated second planar coils positioned within the distal end, wherein respective planes of the second planar coils are parallel to a second plane orthogonal to the first plane;
- and
- a processor, configured to process respective first and second signals generated by the first and second planar coils in response to magnetic resonance of tissue in the body cavity, and to process the first signals while applying a first phase delay responsive to a first separation between the first coils and to process the second signals while applying a second phase delay responsive to a second separation between the second coils so as to image the tissue.
A method for magnetic resonance imaging, comprising:
- inserting a probe having a flexible insertion tube and a distal end into a body cavity;
- positioning an array of spatially separated coils within the distal end;
- and
- processing respective signals generated by the coils in response to magnetic resonance of tissue in the body cavity while applying a phase delay responsive to a separation between the coils, so as to image the tissue.
