在计算机辅助干预（CAI）的背景下，术中获取患者解剖结构是一项关键技术。超声（US）作为一种介入成像方式具有主要优势，因为它是实时的、低成本的，并且不会使患者或医生暴露在有害的辐射中。为了推进与美国相关的研究，本文的目的是开发和评估美国CAI应用程序的开源框架。我们开发了开源软件模块MITK-US，用于获取和处理美国数据，作为著名的医学成像交互工具包（MITK）的一部分。为了证明它的实用性，我们应用该模块实现了一个新的概念，即美国引导针头插入。通过确定简单示例应用程序和更复杂的指针制导系统的帧率和延迟来评估US模块的性能。MITK-US已经成功地用于实现这两个示例应用程序。现代笔记本电脑的帧率达到每秒24帧以上。测量到的延迟大约为250毫秒或更短。MITK-US可以被认为是美国CAI应用程序的一个可行的快速原型环境。
Intra-procedural acquisition of the patient anatomy is a key technique in the context of computer-assisted interventions (CAI). Ultrasound (US) offers major advantages as an interventional imaging modality because it is real time and low cost and does not expose the patient or physician to harmful radiation. To advance US-related research, the purpose of this paper was to develop and evaluate an open-source framework for US-based CAI applications.We developed the open-source software module MITK-US for acquiring and processing US data as part of the well-known medical imaging interaction toolkit (MITK). To demonstrate its utility, we applied the module to implement a new concept for US-guided needle insertion. Performance of the US module was assessed by determining frame rate and latency for both a simple sample application and a more complex needle guidance system.MITK-US has successfully been used to implement both sample applications. Modern laptops achieve frame rates above 24 frames per second. Latency is measured to be approximately 250 ms or less.MITK-US can be considered a viable rapid prototyping environment for US-based CAI applications.
