摘要

在本文中，我们介绍了专门用于大鼠脑7特斯拉MRI的植入式微线圈的发展，用于肿瘤和神经退行性疾病的诊断和监测。这些线圈是灵活和无线的，易于批量制造。我们还首次提出了封装对线圈特性、f0和Q因子的影响的研究。PDMS包装的优化使我们能够利用植入的柔性微天线实现第一个大鼠脑的活体图像。

Implantable wireless microcoils for 7Tesla Magnetic Resonance Imaging of the rat brain: Optimization of the PDMS packaging

In this paper, we present the development of implantable microcoils specifically dedicated to 7Tesla MRI of the rat brain for the diagnosis and monitoring of tumors and neurodegenerative diseases. These coils are flexible and wireless, with an easy batch fabrication. We also present for the first time a study of the packaging effects on the characteristics of the coil, f0 and Q factor. The optimization of the packaging with PDMS allows us to realize the first in vivo image of the rat brain using an implanted flexible microantenna.
