摘要

我们已经开发了一种用于乳腺癌症成像的微波成像设备，该设备可以在MR成像系统中同时使用。微波测量系统由16个单极天线的水平阵列组成，这些天线可以垂直移动，以实现乳房的全3D覆盖。所有兼容性问题都已解决。该运动是使用一种新颖的3D打印传动装置实现的。初步结果表明，该系统能够准确地恢复三维形状变化物体的大小、形状、位置和特性。这是MR临床微波乳腺成像的关键一步。

3D-printed gear system for antenna motion in an MR environment: initial phantom imaging experiments.

We have developed a microwave imaging device for breast cancer imaging that can be used concurrently inside an MR imaging system. The microwave measurement system is comprised of a horizontal array of 16 monopole antennas that can be moved vertically for full 3D coverage of the breast. All compatibility issues have been addressed. The motion is achieved using a novel 3D printed gearing device. Initial results demonstrate that the system is capable of accurately recovering the size, shape, location and properties of a 3D shape varying object. This is a critical step towards clinical microwave breast imaging in the MR.
