This paper presents improvements to the plane-based technique for calibrating freehand 3D ultrasound systems. The improvements are designed to make it easier for inexperienced users to perform plane-based calibration and to know that they have got a reliable result. In particular, we enable the calibration to be performed using water at room temperature while producing a result that is valid for average soft tissue and we show how it is possible to provide feedback on the reliability of the calibration using a metric based on the curvature of the calibration criterion function. We present comprehensive results showing that these innovations improve the precision of the calibration and offer useful feedback to the user.
本文介绍了对基于平面的徒手三维超声系统校准技术的改进。这些改进旨在使缺乏经验的用户更易于执行基于平面的校准，并让他们知道自己已获得可靠的结果。特别是，我们能够在室温下使用水进行校准，同时得出对平均软组织有效的结果，并且我们展示了如何基于校准准则函数的曲率，使用一种度量来提供关于校准可靠性的反馈。我们展示的综合结果表明，这些创新提高了校准的精度，并为用户提供了有用的反馈。
