Abstract

Goal: This study presents a novel MRI coil design approach explicitly tailored for chick embryo measurements, with the primary objective of improving sensitivity and coverage. Methods: The limitations posed by conventional birdcage coils were addressed by introducing a curvature feature into a standard coil. The performance of the modified coil was assessed using EM simulations and experimental evaluations, which were subsequently validated using a 7 T MRI scanner. A comparative analysis was conducted against a standard quadrature low-pass birdcage coil to evaluate key factors. Results: The proposed coil demonstrated improved SNR and uniformity, particularly in the proximity of the end-rings. These results were consistent with the findings obtained from the simulations. Conclusions: The use of our innovative birdcage coil design holds promise and offers practical potential for in ovo studies.

用于胎儿磁共振成像的改进型正交鸟笼线圈，带有弯曲特征

目标：本研究提出了一种明确针对小鸡胚胎测量的新型磁共振成像线圈设计方法，其主要目标是提高灵敏度和覆盖范围。方法：通过在标准线圈中引入曲率特征，解决了传统鸟笼线圈的局限性。利用电磁模拟和实验评估对改进线圈的性能进行了评估，随后利用 7 T 磁共振成像扫描仪对其进行了验证。与标准正交低通鸟笼线圈进行了对比分析，以评估关键因素。结果：拟议的线圈提高了信噪比和均匀性，尤其是在靠近端环的区域。这些结果与模拟结果一致。结论使用我们创新的鸟笼线圈设计前景广阔，为胎儿研究提供了实用潜力。
