Abstract
Techniques are disclosed for determining coefficients for use in correcting a magnetic relaxation time constant, T, value obtained via magnetic resonance imaging when a pulse rate was at a first pulse rate value to a T value reflecting the T value that would have been obtained if the pulse rate was at a second pulse rate value. The technique includes, for each region of interest, pairing an obtained derivative, m, and an obtained offset, c, as an ordered pair (c, m). The technique further includes fitting the obtained plurality of ordered pairs (c, m) to a polynomial function, and determining the values of the coefficients from the polynomial function.
