Breast cancer detection using microwave holography
Breast cancer is one of the most common forms of cancer in women. X-ray mammography is the most widely used technique for early detection but has limitations. In this paper, an alternative approach for breast cancer detection using microwave imaging is presented. This is based upon microwave indirect holographic approach, central to which is the use of a synthetic reference beam. This approach has benefits in terms of simplicity and expense. Experimental results using a simple breast phantom are included to demonstrate the potential of this approach
Investigation of microwave antennas in lossy media for medical applications
For several years, microwave engineers have dreamed of using non-ionising electromagnetic waves in medical imaging applications. The rate of evolution of microwave techniques for medical application has been immense and shows no signs of relenting. Since the limitations of X-ray mammography are well reported, alternative techniques using microwaves for breast cancer detection are developed. Some of these techniques have progressed to the point where positive clinical experience has emerged

A holographic solution for concealed object detection
A novel, inexpensive technique for the detection of concealed objects is outlined. The ability of this intensity only technique to recover phase information about the object under test proves to be significant in the imaging of concealed objects. A brief examination of the underlying theory followed by a description of the experimental system is presented along with some initial results obtained from the imaging of three different concealed objects
Early stage breast cancer detection using indirect microwave holography
A novel microwave imaging approach for early stage breast cancer detection is described. The proposed technique involves the use of an Indirect Microwave Holographic technique employing a patented synthetic reference wave. This approach offers benefits in terms of simplicity, expense, comfort and safety when compared to current mammography techniques. Experimental results using a simulated phantom are included to demonstrate the validity of this technique
A microwave indirect holographic system for security and medical imaging applications
This work details how an indirect microwave holographic technique originally developed for antenna measurements can be extended to imaging applications. It outlines how complex field patterns can be reconstructed from holographic intensity patterns. It also outlines how images of both metallic and non-metallic objects can be obtained from these patterns. Results are presented to demonstrate how this technique can be applied in the areas of concealed weapons detection and medical imaging
