An RF multicoil array for high resolution imaging of the breast is presented. The RF multicoil is incorporated into a dedicated breast imaging apparatus that holds either breast in gentle compression during imaging. Simulations and imaging experiments demonstrate the high sensitivity and RF homogeneity of the multicoil array. Direct comparisons are made between the multicoil and a surface coil. In vivo images are presented to demonstrate the homogeneity of the RF field of the multicoil over the entire breast. An in vivo image of both high temporal and spatial resolution is shown, which demonstrates the sensitivity of the RF multicoil array that may be achieved in a practical imaging experiment.
本文介绍了一种用于乳腺高分辨率成像的射频多线圈阵列。该射频多线圈被集成到一台专用乳腺成像设备中,该设备在成像过程中对双侧乳腺进行轻柔压迫。仿真和成像实验证明了多线圈阵列具有高灵敏度和射频均匀性。对多线圈和表面线圈进行了直接比较。展示了体内图像,以证明多线圈在整个乳腺上的射频场均匀性。还展示了一幅具有高时间和空间分辨率的体内图像,该图像证明了在实际成像实验中可实现的射频多线圈阵列的灵敏度。
