Anatomical measurements from ultrasound data

Abstract

The application discloses a computer-implemented method () of providing a model for estimating an anatomical body measurement value from at least one 2-D ultrasound image including a contour of the anatomical body, the method comprising providing () a set of 3-D ultrasound images of the anatomical body; and, for each of said 3-D images, determining () a ground truth value of the anatomical body measurement; generating () a set of 2-D ultrasound image planes each including a contour of the anatomical body, and for each of the 2-D ultrasound image planes, extrapolating () a value of the anatomical body measurement from at least one of an outline contour measurement and a cross-sectional measurement of the anatomical body in the 2-D ultrasound image plane; and generating () said model by training a machine-learning algorithm to generate an estimator function of the anatomical body measurement value from at least one of a determined outline contour measurement and a determined cross-sectional measurement of a contour of the anatomical body within a 2-D ultrasound image using the obtained ground truth values, extrapolated values and at least one of the outline contour measurements and the cross-sectional measurements as inputs of said machine-learning algorithm. A computer-implemented method of deploying such a model, a computer program product, an ultrasound image processing apparatus and an ultrasound imaging system adapted to implement such methods are also disclosed.
