摘要

Method and system to calibrate a mathematical model of liver iron estimation from magnetic resonance imaging measurements Method and system to obtain a correction factor (f) of a certain mathematical model (7) for estimation of hepatic iron to be able to apply this model to estimate liver iron from images (i1, i2) taken with any resonance machine magnetic for this purpose, images (i1 ", i2") of a device (1) comprising a series of tubes (c, d, e, f, g) filled with iron solutions are taken in the magnetic resonance machine. At known concentrations, extracting from these images some measurements (c1, c2, ..., f2, g2) and applying the mathematical model (7) to the measurements to obtain an estimated value (ed, ee, ef, eg) of iron liver associated with each tube. Then, the estimated liver iron values of each tube are compared with the original liver iron values associated with each tube and the deviation or correction factor (f) is obtained.
