Research output: Patents, agreements, assignments and companiesPatents granted


A three-dimensional (3D) ultrasound imaging system (10) for assessing spinal structure problems comprises an ultrasound scanner (11) to capture ultrasound images, a spatial sensor (13) to record the position and orientation of the captured ultrasound images and a software module (21) to mark features of vertebra in the captured ultrasound images. The marked features (41) are connected by lines (42) in order to calculate angles and distances between the marked features (41) for the calculation of the Cobb angle and spinal rotation angle based on the calculated angles and distances, wherein the marked features (41) are reflections of the surfaces of the vertebra.
