超声成像适用于许多医学领域，但二维超声用户的培训需求以及技能和获取的图像质量的差异限制了其更广泛的采用和使用。具有已知参考系的低成本体积超声有可能降低这些操作员依赖的障碍并增强超声成像的临床实用性。在本文中，我们改进了之前基于扫描仪的研究原型，为现有的临床二维超声系统实现了多功能体积成像平台。我们提出改进的数据采集和图像重建方案，以提高质量、简化工作流程并提供实时视觉反馈。我们在 Vimedix 模拟器上使用该平台，以及使用各种临床超声系统和探头在体模和体内目标上展示了初步结果。
Ultrasound imaging has indications across many areas of medicine, but the need for training and the variability in skill and acquired image quality among 2-D ultrasound users have limited its wider adoption and utilization. Low-cost volumetric ultrasound with a known frame of reference has the potential to lower these operator-dependent barriers and enhance the clinical utility of ultrasound imaging. In this paper, we improve upon our previous research-scanner-based prototype to implement a versatile volumetric imaging platform for existing clinical 2-D ultrasound systems. We present improved data acquisition and image reconstruction schemes to increase quality, streamline workflow, and provide real-time visual feedback. We present initial results using the platform on a Vimedix simulator, as well as on phantom and in vivo targets using a variety of clinical ultrasound systems and probes.
