项目摘要

Project Summary/Abstract Novel Software Tools for Rational Design and Assessment of MR coils The goal of this project is to develop a comprehensive software package for the design and evaluation of radiofrequency (RF) coils for applications in magnetic resonance imaging (MRI). By means of an intuitive graphical user interface, RF engineers will be able to design highly performing receive and transmit coil arrays, tailoring the shape of the individual elements to the specific imaging task and optimally arranging them around the object of interest, thanks to accurate predictions of coil performance. We will also develop standardized evaluation protocols to quantitatively assess coils against well-defined theoretical performance limits, which are calculated by applying electrodynamics principles and provide an absolute reference, independent on any particular coil geometry. We will integrate various software tools into a modular and flexible software architecture, which will enable other researchers to add extensions and develop stand-alone applications. We will validate the accuracy of the simulation tools and evaluate the software utility through a network of beta testers. In addition to coil design, our comprehensive package will enable to test novel pulse sequences and image reconstruction algorithms, making rigorous development of new ideas accessible to the scientific community, including those with no access to MRI systems. The final software, which will be publicly distributed through a dedicated website with a maintenance plan beyond the duration of the project, will become an invaluable tool that will positively impact the field of medical imaging, with benefits for the entire community.

项目摘要/摘要用于理性设计和评估MR线圈的新型软件工具该项目的目的是为设计和评估开发一个综合的软件包用于磁共振成像（MRI）应用的射频（RF）线圈。通过直觉图形用户界面，RF工程师将能够设计高性能的接收和传输线圈阵列，根据特定的成像任务调整各个元素的形状，并最佳地安排它们感兴趣的对象，得益于对线圈性能的准确预测。我们还将开发标准化评估协议以定量评估针对明确定义的理论性能限制的线圈，这是通过应用电动力学原理计算并提供绝对参考，独立于任何特定的线圈几何形状。我们将将各种软件工具集成到模块化和灵活的软件中体系结构，这将使其他研究人员能够添加扩展并开发独立的应用程序。我们将验证模拟工具的准确性，并通过Beta网络评估软件实用程序测试人员。除了线圈设计外，我们的综合包装还可以测试新颖的脉冲序列和图像重建算法，使科学访问的新想法的严格发展社区，包括无法访问MRI系统的社区。最终软件将公开通过专门的网站分发，其维护计划超出了项目的持续时间，将成为将对医学成像领域产生积极影响的宝贵工具，并为整个好处社区。
