Abstract
A method for providing an image of the human heart's electrical system derives time-of-flight data from an array of EKG electrodes and this data is transformed into phase information. The phase information, treated as a hologram, is reconstructed to provide an image in one or two dimensions of the electrical system of the functioning heart.
Claims11
A method of depicting data relating to a patient's heart, comprising:
- receiving heart generated impulses at a plurality of locations on the patient's body,
- determining relative phase information from ones of said impulses as received, according to their respective times of reception at said plurality of locations, and
- reconstructing an image of the electrical system of said patient's heart from said phase information.
A method of imaging the electrical system of a patient's heart, comprising:
- receiving heart generated electrical impulses at closely spaced locations upon said patient's body, in proximity to the patient's heart,
- determining time-of-flight data for said electrical impulses at said spaced locations, said time-of-flight data being defined relative to a reference location,
- converting said time-of-flight data into phase data holographically representative of the electrical source configuration transmitting said impulses, and
- reconstructing an image of the electrical system of said patient's heart from said phase data.
1 more element
A method of generating an image of a heart comprising the steps of:
- measuring a plurality of electrical impulses generated by the heart at a plurality of locations on a patient's chest,
- determining wave propagation characteristics of ones of said plurality of electrical impulses, and
- generating a holographic representation of the electrical system of the heart based on said wave propagation characteristics.
