磁共振成像是一种固有的信噪比不足的技术,其限制了空间分辨率、诊断图像质量,并且导致通常较长的采集时间,这易于产生运动伪影。当接收线圈由于缺乏灵活性或需要衬垫以使患者舒适而具有较差的配合时,这种限制会加剧。在这里,我们报告了一种新的方法,使用印刷制造接收线圈。我们的方法可以实现高度灵活、重量极轻的一致性设备。我们表明,这些设备表现出类似于更高的信噪比比传统的,在临床情况下,线圈可以被移位超过18毫米远离身体。此外,我们还提供详细的材料特性和部件性能分析。原型阵列被整合到婴儿毯中用于体内研究。这项工作提出了第一个功能齐全,印刷线圈的1.5和3 T临床扫描仪。 信噪比是目前限制磁共振成像诊断图像质量和患者条件的关键因素之一。在此,Corea等人使用完全印刷的柔性接收线圈,符合患者身体,以改善临床扫描仪中的信号和患者舒适度。
Magnetic resonance imaging is an inherently signal-to-noise-starved technique that limits the spatial resolution, diagnostic image quality and results in typically long acquisition times that are prone to motion artefacts. This limitation is exacerbated when receive coils have poor fit due to lack of flexibility or need for padding for patient comfort. Here, we report a new approach that uses printing for fabricating receive coils. Our approach enables highly flexible, extremely lightweight conforming devices. We show that these devices exhibit similar to higher signal-to-noise ratio than conventional ones, in clinical scenarios when coils could be displaced more than 18 mm away from the body. In addition, we provide detailed material properties and components performance analysis. Prototype arrays are incorporated within infant blankets for in vivo studies. This work presents the first fully functional, printed coils for 1.5- and 3-T clinical scanners. Signal-to-noise ratio is one of the key factors that currently limit the diagnostic image quality and patient conditions of magnetic resonance imaging. Here, Corea et al. use fully printed flexible receive coils, conforming to patient bodies, to improve signals and patient comfort in clinical scanners.
