我们提出了一个弹性成像系统，使用徒手三维超声。提供了一个审查的标准弹性成像方法，已适应于这一目的。扫描协议是简单的和有前途的结果，从徒手扫描的三维应变图像。鲁棒性是一个问题，但是，和错误的主要来源进行了解释。通过丢失校正和帧滤波等方法提高了手绘图像的质量。从这些技术的应用结果提供了一个指示的发展链，这将导致一个系统，既易于使用，并产生可靠的，高质量的图像。
We present an elastography system using freehand 3D ultrasound. A review is provided of the standard elastography methods that have been adapted for this purpose. The scanning protocol is simple and promising results are presented of 3D strain images from freehand scans. Robustness is a problem, however, and the main sources of error are explained. Measures have been developed to improve the quality of the freehand images by means of drop-out correction and frame filtering. Results from the application of these techniques provide an indication of development strands which should lead to a system that is both easy-to-use and produces reliable, high quality images.
