SYSTEM AND METHOD FOR AUTOMATIC PLANNING OF TWO-DIMENSIONAL VIEWS IN THREE-DIMENSIONAL MEDICAL IMAGES

摘要

FIELD: physics.SUBSTANCE: method includes: estimating a statistical model of positions of anatomical points; training an anatomical point detector; obtaining a three-dimensional image of the region of interest; detecting a plurality of anatomical point candidates; searching for the best configuration of anatomical points among the candidates; constructing view planes based on the found configuration of anatomical points; estimation of parameters of said statistical model is carried out using an annotated plurality of three-dimensional images; the anatomical point detector is trained using energy of said statistical model as parts of a loss function; detection of the plurality of anatomical point candidates is carried out with an anatomical point detector which is trained using said algorithm; the search for the best configuration of anatomical points is carried out using a greedy iterative search of a configuration which minimises said energy of the statistical model. System realises method's actions.EFFECT: high efficiency of automatic planning of two-dimensional views in three-dimensional medical images.11 cl, 5 dwg
