Method for mapping internal body tissue
First Claim
1. A method for mapping tissue of a body, the tissue being at least partially shielded by bone, comprising:
- (a) determining the density of the bone as a function of spatial coordinates;
(b) applying a first input signal to the tissue through the surface of the body;
(c) measuring a first output signal representing said input signal as modified by the tissue;
(d) determining a relationship between said input signal and said output signal, said relationship being a function of the density of the bone as well as the density of the tissue; and
(e) employing the result of step (a) in step (d) to reduce the number of unknowns in said step (d).

Abstract
A method for mapping internal body tissue. The method preferably includes determining the spatial distribution of bone tissue of a patient that shields target soft tissue, the structure of which it is desired to determine and monitor, and subjecting the patient to changing electric, magnetic or electromagnetic fields adapted for interacting with the target soft tissue as a function of the spatial distribution of the soft tissue. Electric, magnetic or electromagnetic energy that is transmitted through the bone and the soft tissue is analyzed to infer the spatial distribution of the soft tissue with the assistance of knowledge of the spatial distribution of the bone tissue.
