Image-guided medical interventions and surgeries rely on one or more imaging feedback to monitor the treatment and to guide an interventionist or surgeon in placing and operating a medical tool or probe with respect to a target tissue. Conventional imaging techniques such as X-ray, CT (computed tomography) scan, and MRI (magnetic resonance imaging) impose several shortcomings for many image-guided medical operations. For instance, X-ray and CT scans are harmful to the human body in large doses, while MRI and US (ultrasound) are known to be safe. On the other hand, MRI has prohibitively slow imaging speeds, requires special facilities, incurs high costs, and cannot be moved into the operating room. In contrast, US imaging is relatively cheap, portable, and operates in real-time (24-30 fps), making it the preferred imaging technology

图像引导的医疗干预和手术依靠一个或多个成像反馈来监测治疗并指导干预医生或外科医生相对于目标组织放置和操作医疗工具或探针。 X 射线、CT（计算机断层扫描）扫描和 MRI（磁共振成像）等传统成像技术对许多图像引导的医疗手术存在一些缺点。例如，X射线和CT扫描在大剂量时对人体有害，而MRI和US（超声波）已知是安全的。另一方面，MRI成像速度过慢，需要特殊设施，成本高昂，并且无法移入手术室。相比之下，US 成像相对便宜、便携且实时运行（24-30 fps），使其成为首选成像技术
