First Claim
Patent Images
1. A method comprising:
- acquiring an image of or pertaining to a heart;
acquiring a first data set pertaining to one or more locations of a heart vector of the heart, the first data set being spatially correlated with the image;
acquiring a second data set pertaining to one or more locations of the heart vector of the heart;
receiving first and second data sets at a processor; and
registering, via the processor, a representation of a probe with the image by registering the location of the heart vector from the first data set with the location of the heart vector from the second data set, wherein the second data set is acquired using at least one lead positioned on a skin surface, wherein the location of the heart vector from the second data set can be determined relative to the lead, and wherein the location of the probe can also be determined relative to the lead.

1. A method comprising:
-
acquiring an image of or pertaining to a heart; acquiring a first data set pertaining to one or more locations of a heart vector of the heart, the first data set being spatially correlated with the image; acquiring a second data set pertaining to one or more locations of the heart vector of the heart; receiving first and second data sets at a processor; and registering, via the processor, a representation of a probe with the image by registering the location of the heart vector from the first data set with the location of the heart vector from the second data set, wherein the second data set is acquired using at least one lead positioned on a skin surface, wherein the location of the heart vector from the second data set can be determined relative to the lead, and wherein the location of the probe can also be determined relative to the lead. - View Dependent Claims (2, 3)

4. A method comprising:
-
acquiring an image of or pertaining to a heart; acquiring a first and a second data set using a lead system; receiving the first and second data sets at a processor; registering, via the processor, a location of a first heart vector from the first data set relative the lead system at a skin surface of an imaged subject, wherein the first heart vector represents a summation of electrical currents at a particular time, the summation having a direction and an amplitude; registering, via the processor, a location of a second heart vector from the second data set relative to the lead system; and adjusting the size or position of the image dependent on a change in the location between the first and second heart vector generated from the first and second data sets, respectively. - View Dependent Claims (5, 6)

7. A system comprising:
-
a lead system located at a skin surface of an imaged subject and operable to acquire a first data set and a second data set pertaining to one or more locations of a first and second heart vector, respectively, of the heart; a processor configured to be communicatively coupled to a probe and further configured to register the first heart vector from the first data set with the second heart vector from the second data set, the probe being configured to be located in or adjacent to a heart; memory configured to store; an image of at least a portion of the heart; the first data set pertaining to one or more locations of the first heart vector of the heart, the first data set being spatially correlated with the image; the second data set pertaining to one or more locations of the second heart vector of the heart; and a display configured to display the image and a representation of the probe, the image being registered with the representation of the probe by the registration of the first heart vector from the first data set with the second heart vector from the second data set, wherein the location of the heart vector from the second data set can be determined relative to the lead, and wherein the location of the probe can also be determined relative to the lead. - View Dependent Claims (8, 9, 10, 11, 12, 13)
