Abstract
Description
φlm=∫V(θ, ψ)Ylm(θ, ψ)dΩ
where V(θ, φ) is the measured potential over the probe radius R and dΩ is the differential solid angle and, in spherical coordinates, is defined as:
dΩ=sin θdθdψ
Note that p times q equals the total number of electrodes on the spherical probe array. The angle θ ranges from zero to π radians and ψ ranges from zero to 2π radians.
where, V(x) represents the potential at any desired point defined by the three-dimensional vector x and, Vi represents each of n known potentials at a point defined by the three-dimensional vector i and, k is an exponent that matches the physical behavior of the tissue medium.
