Abstract

A microwave-based breast cancer screening and early diagnostics imaging system is provided. The microwave-based breast cancer screening and early diagnostics imaging system uses mild compression to electromagnetically homogenize the heterogeneous breast media or, to some degree, decrease the breast dimension to 2D. The device is capable of providing multi-angle examination, if necessary, and produces horizontal and vertical cross-sectional images based on the polarization of the antennas used for scanning. Merging two-sectional images can give a possibility of 3D microwave representation of the breast tissue that allows identification of the malignant/cancerous/harmful tissues/cells through cross validation.

First claim

What is claimed is:

1 . A breast cancer screening system, comprising:
a bed compartment of a rectangular shape, wherein the bed compartment is located inside the breast cancer screening system, and an opening is located on the bed compartment and allows a breast to be positioned, wherein the bed compartment comprises antennas to receive microwave signals for acquiring microwave images from S-parameters and making a comparison of the S-parameters, a disk-shaped turntable mechanism positioned inside the bed compartment, wherein the disk-shaped turntable mechanism comprises gaps located on the disk-shaped turntable mechanism, and the disk-shaped turntable mechanism allows for collecting data from different horizontal and vertical breast cross-sections through an angular motion, a horizontally polarized antenna block located on the disk-shaped turntable mechanism, wherein horizontally polarized linear-array antennas are located on the horizontally polarized antenna block, a vertically polarized antenna block located on the disk-shaped turntable mechanism, wherein vertically polarized linear-array antennas are located on the vertically polarized antenna block, and a rail system positioned on the disk-shaped turntable mechanism, wherein the rail system allows the breast to be compressed via a planar or linear movement of the horizontally polarized antenna block and a planar or linear movement of the vertically polarized antenna block.

2 . The breast cancer screening system according to claim 1 , further comprising impedance matching media positioned on a front surface of the horizontally polarized antenna block and the vertically polarized antenna block, wherein the impedance matching media comes into contact with the breast.
