Abstract
A location pad includes multiple field-generators and a frame. The multiple field-generators are configured to generate respective magnetic fields in a region-of-interest of a patient organ, so as to measure a position of a medical instrument in the region-of-interest. The frame is transparent to an X-ray radiation, and is configured to fix the multiple field-generators at respective positions surrounding the region-of-interest.
Claims20
A location pad, comprising:
- (i) multiple field-generators, which are configured to generate respective magnetic fields in a region-of-interest of a patient organ, for measuring a position of a medical instrument in the region-of-interest;
- (ii) a frame, which is configured to fix the multiple field-generators at respective positions surrounding the region-of-interest, wherein the frame is transparent to an X-ray radiation;
- and
- (iii) a fixing assembly associated with both the multiple field-generators and the frame, wherein the fixing assembly is configured to allow the multiple field-generators to move to multiple locations of a surface of the frame in order to adjust the size and shape of the region-of-interest.

A method for producing a location pad, the method comprising:
- (a) providing multiple field-generators for generating respective magnetic fields in a region-of-interest of a patient organ, so as to measure a position of a medical instrument in the region-of-interest;
- (b) utilizing a fixing assembly to adjust the spatial positioning of the multiple field-generators in order to set the size and shape of the region-of-interest;
- and
- (c) fixing the multiple field-generators on a frame at respective positions surrounding the region-of-interest, wherein the frame is transparent to X-ray radiation at least at the region-of-interest.
1 more element
A method, comprising:
- (a) positioning a location pad relative to a region-of-interest of a patient, wherein the location pad comprises a frame that fixes multiple field-generators at respective positions surrounding the region-of-interest, and wherein the frame is transparent to an X-ray radiation at least at the region-of-interest;
- (b) adjusting the spatial position of the multiple filed-generators utilizing a fixing device of the frame in order to set the size and shape of the region-of-interest;
- (c) inserting a medical instrument into the region of interest;
- (d) tracking a position of the medical instrument using the field-generators;
- and
- (e) simultaneously with tracking the position, irradiating the region-of-interest with a fluoroscopic imaging system so as to produce an image of the region-of-interest.
