It has been observed that the distribution of the training targets used to calculate the GREIT reconstruction matrix has a strong impact on its chief figure of merit, the amplitude response (AR). We found that uniform AR requires a minimum target distance to the domain boundary, and target density gradient toward the centre has less impact on uniform AR.
