Ovarian follicle count and size determination using transvaginal ultrasound scans

Abstract

Disclosed is a computer-implemented method for determining an ovarian follicle count and size (diameter) from a pair of 2-D transvaginal ultrasound scans. The method comprises receiving the pair of 2-D (two-dimensional) transvaginal ultrasound scans, each scan comprising a plurality of 2-D ultrasound images captured along a translation direction of an ultrasound probe used to capture said scan, the respective translation directions being at least approximately orthogonal, and for each of said scans, the method further comprising detecting candidate follicles in the plurality of 2-D ultrasound images of the at least one 2-D transvaginal ultrasound scan; and segmenting the detected candidate follicles to determine an average diameter for each candidate follicle; selecting the 2-D transvaginal ultrasound scan including the candidate follicle having the largest average diameter; and presenting the determined average diameters and the segmentations of the detected candidate follicles of the selected 2-D transvaginal ultrasound scan. A computer program product, ultrasound image processing device and ultrasound imaging system adapted to implement this method are also disclosed.
