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.

项目概要/摘要 用于合理设计和评估 MR 线圈的新型软件工具 该项目的目标是开发一个用于设计和评估的综合软件包 用于磁共振成像 (MRI) 的射频 (RF) 线圈。通过直观的方式 图形用户界面，射频工程师将能够设计高性能的接收和发射线圈阵列， 根据特定的成像任务定制各个元素的形状并对其进行最佳排列 得益于对线圈性能的准确预测，我们可以准确地预测感兴趣的对象。我们还将制定标准化 评估协议，根据明确的理论性能限制定量评估线圈，这些限制是 通过应用电动力学原理计算并提供绝对参考，独立于任何 特殊的线圈几何形状。我们将各种软件工具集成为模块化、灵活的软件 架构，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 网络评估软件实用性 测试人员。除了线圈设计之外，我们的综合套件还能够测试新颖的脉冲序列和 图像重建算法，使科学界能够严格开发新想法 社区，包括那些无法使用 MRI 系统的人。最终软件将公开 通过一个专门的网站分发，并在项目持续时间之外提供维护计划，将 成为一种宝贵的工具，将对医学成像领域产生积极影响，为整个行业带来好处 社区。
