A real-time ultrasound image processing technique for computer-assisted and image-guided interventional technologies

图像引导的医疗介入和手术依赖于一个或多个成像反馈来监测治疗并引导介入医师或外科医生相对于目标组织放置和操作医疗工具或探针。传统的成像技术，例如X射线、CT（计算机断层摄影）扫描和MRI（磁共振成像）对于许多图像引导的医疗操作施加了若干缺点。例如，X射线和CT扫描在大剂量下对人体有害，而MRI和US（超声波）已知是安全的。另一方面，MRI成像速度非常慢，需要特殊设施，成本高，并且不能移动到手术室中。相比之下，US成像相对便宜，便携，实时操作（24-30 fps），使其成为首选的成像技术

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
