Abstract
Spherical receiver coils suitable for magnetic resonance (MR) imaging of the brain are described. Spherical geometry permits high field uniformity with close proximity of the coil to the patient's head giving a good filling factor. Patient acceptability has been good in more than 800 examinations of the brain. Spherical receiver coils of appropriate size can provide a simple and worthwhile improvement over conventional saddle designs for low field MR imaging.
摘要
本文描述了适用于脑部磁共振（MR）成像的球形接收线圈。球形几何形状能够实现高场均匀性，且线圈可贴近患者头部，从而具有良好的填充因子。在800多次脑部检查中，患者对其接受度良好。对于低场MR成像，尺寸合适的球形接收线圈相比传统鞍形设计能够提供一种简单且有价值的改进。
