摘要

三维(3D)超声成像可通过重建二维(2D)超声图像序列来实现。然而,二维超声图像在仰角方向的分辨率通常较低,从而影响三维重建结果的准确性。众所周知,二维超声的横向分辨率大大超过仰角分辨率。通过组合从正交方向获取的扫描序列,可以通过复合重建过程减轻仰角分辨率低的影响。此外,要从多个角度捕捉超声图像,就必须采用覆盖角度大的精确探头定位方法。光学跟踪因其高精度和环境适应性而被广泛用于探头定位。本文采用一种新型大角度精确光学定位方法,通过正交视角扫描和复合重建提高三维超声成像的分辨率。在两个模型上进行的实验证明,与单角度平行扫描相比,我们的方法能显著提高探头仰角方向的重建精度。结果表明,我们的方法有望改善目前的三维超声成像技术。

Elevation Resolution Enhancement Oriented 3D Ultrasound Imaging.

Three-dimensional (3D) ultrasound imaging can be accomplished by reconstructing a sequence of two-dimensional (2D) ultrasound images. However, 2D ultrasound images usually suffer from low resolution in the elevation direction, thereby impacting the accuracy of 3D reconstructed results. The lateral resolution of 2D ultrasound is known to significantly exceed the elevation resolution. By combining scanning sequences acquired from orthogonal directions, the effects of poor elevation resolution can be mitigated through a composite reconstructing process. Moreover, capturing ultrasound images from multiple perspectives necessitates a precise probe positioning method with a wide angle of coverage. Optical tracking is popularly used for probe positioning for its high accuracy and environment-robustness. In this paper, a novel large-angle accurate optical positioning method is used for enhancing resolution in 3D ultrasound imaging through orthogonal-view scanning and composite reconstruction. Experiments on two phantoms proved that our method could significantly improve reconstruction accuracy in the elevation direction of the probe compared with single-angle parallel scanning. The results indicate that our method holds the potential to improve current 3D ultrasound imaging techniques.
