Abstract: An imaging system for generating three-dimensional (3D) images includes an imaging probe for acquiring two-dimensional (2D) image data of a region of interest. A sensor is coupled with the imaging probe to determine positional data related to a position of the imaging probe. A position determination module utilizes the image data acquired with the imaging probe and the positional data determined by the sensor to calculate a probe location with respect to the acquired 2D image data. An imaging module is configured to reconstruct a 3D image of the region of interest based on the 2D image data and the determined probe locations.

Abstract: Methods, systems and computer program products for estimating the gestational age of a fetus are provided. According to one embodiment, the method generates a component image from a segmented ultrasound image of a fetal head. The component image includes one or more edges. The method then identifies a third ventricle within the component image. The method estimates a length of a bi-parietal diameter, based at least in part on the orientation of the third ventricle. Thereafter, the method estimates the gestational age of the fetus.
