Although ultrasound has become an important imaging modality within several medical professions, the benefit of ultrasound depends to some degree on the skills of the person operating the probe and interpreting the image. For some applications, the possibility to educate operators in a clinical setting is limited, and the use of training simulators is considered an alternative approach for learning basic skills. To ensure the quality of simulator-based training, it is important to produce simulated ultrasound images that resemble true images to a sufficient degree. This article describes a method that allows corresponding true and simulated ultrasound images to be generated and displayed side by side in real time, thus facilitating an interactive evaluation of ultrasound simulators in terms of image resemblance, real-time characteristics and man-machine interaction. The proposed method could be used to study the realism of ultrasound simulators and how this realism affects the quality of training, as well as being a valuable tool in the development of simulation algorithms.
尽管超声已成为多个医学专业领域中一种重要的成像方式，但超声的优势在一定程度上取决于操作探头和解读图像人员的技能。对于某些应用而言，在临床环境中培训操作人员的可能性有限，因此使用训练模拟器被视为学习基本技能的一种替代方法。为确保基于模拟器的培训质量，生成与真实图像足够相似的模拟超声图像非常重要。本文介绍了一种方法，该方法能够实时生成并并排显示对应的真实和模拟超声图像，从而便于就图像相似度、实时特性和人机交互对超声模拟器进行交互式评估。所提出的方法可用于研究超声模拟器的逼真度以及这种逼真度如何影响培训质量，同时也是模拟算法开发中的一种宝贵工具。
