手持式 2D 超声对于术中成像非常有用，但需要一些重建工作才能创建 3D US 体积，除非使用大型且昂贵的 3D US 探头。与涉及全局或局部跟踪算法（遭受抖动和复杂性或漂移）的常见探针跟踪方法不同，我们建议使用局部传感器的组合来重建具有多个自由度的探针轨迹。所提供的传感器是非常低成本的光学鼠标和 Wii 遥控器，但可以实现灵活的 3D US 采集，而无需全局跟踪开销。然后将所得轨迹用作动态扩展、像素最近邻 3D US 体积重建的输入。
Handheld 2D ultrasound is very useful for intra-operative imaging, but requires some reconstruction effort in order to create 3D US volumes, unless one is using large and expensive 3D US probes. Unlike common probe tracking approaches involving either global or local tracking algorithms (suffering from jitter and complexity or from drift), we propose to use a combination of local sensors to reconstruct the probe trajectory with multiple degrees of freedom. The presented sensors are very low-cost- optical mice and a Wii Remote - yet enable flexible 3D US acquisition with no global tracking overhead. The resulting trajectories are then used as input for a dynamically expanding, pixel-nearest-neighbor 3D US volume reconstruction.
