Abstract
A location pad includes two or more field-generators, and a frame. The field-generators are configured to generate respective magnetic fields at least in a region-of-interest (ROI) of a patient organ, for measuring a position of a medical instrument in the ROI. The frame is coupled with tissue that is at least partially surrounding the organ and is configured to fix the two or more field-generators at respective positions surrounding the ROI.
Claims10
A location pad, comprising:
- two or more field-generators, which are configured to generate respective magnetic fields at least in a region-of-interest (ROI) of a patient organ, for measuring a position of a medical instrument in the ROI;
- and
- a frame, which is coupled with tissue that is at least partially surrounding the organ and is configured to fix the two or more field-generators at respective positions surrounding the ROI.
A system, comprising:
- a location pad, comprising:
- two or more field-generators, which are configured to generate respective magnetic fields at least in a region-of-interest (ROI) of a patient organ, for measuring a position of a medical instrument in the ROI;
- and
- a frame, which is coupled with tissue that is at least partially surrounding the organ, and is configured to fix the two or more field-generators at respective positions at least partially surrounding the ROI;
- a position sensor, which is coupled with the medical instrument and is configured, in response to the respective magnetic fields, to generate a position signal indicative of the position of the medical instrument;
- and
- a processor, which is configured, based on the position signal, to estimate the position of the medical instrument.
