Three-dimensional (3D) ultrasound imaging system for assessing scoliosis

Abstract

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. 一种用于评估脊柱结构问题的三维(3D)超声成像系统(10)，包括：捕获超声图像的超声扫描仪(11)；记录被捕获的超声图像的位置和取向的空间传感器(13)；以及在被捕获的超声图像中标记脊椎的特征的软件模块(21)。被标记特征(41)用线(42)连接，以便计算被标记特征(41)之间的夹角和距离，用于根据计算得到的夹角和距离计算Cobb角和脊柱旋转角，其中被标记特征(41)是脊椎表面的回波。
