Webb1 juni 2016 · The biplane modified Simpson method assumes that the LA is cylindrical in shape and that the total volume can be calculated from a series of stacked cylindrical discs [5], [18]. As the LA is not perfectly cylindrical, each measurement may exclude small portions of each disc, which can lead to underestimation of volume [9], [19].
