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.
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很大的优势，因为它是实时的，成本低，并且不会使患者或医生暴露在有害辐射下。为了推进与 US 相关的研究，本文旨在开发和评估一个基于 US 的 CAI 应用的开源框架。
我们开发了开源软件模块 MITK-US，用于采集和处理 US 数据，作为知名的医学成像交互工具包（MITK）的一部分。为了展示其效用，我们应用该模块实现了一种新的 US 引导针插入概念。通过确定简单示例应用程序和更复杂的针引导系统的帧率和延迟来评估 US 模块的性能。
MITK-US 已成功用于实现这两个示例应用程序。现代笔记本电脑的帧率超过 24 帧/秒。延迟测量约为 250 毫秒或更短。
MITK-US 可被视为基于 US 的 CAI 应用的可行快速原型开发环境。
