Medical imaging with a microwave tomographic scanner [PDF]
IEEE Transactions on Biomedical Engineering, 1990 A microwave tomographic scanner for biomedical applications is presented. The scanner consists of a 64 element circular array with a useful diameter of 20 cm. Electronically scanning the transmitting and receiving antennas allows multiview measurements with no mechanical movement. Imaging parameters are appropriate for medical use: a spatial resolution

Continuous-capture microwave imaging [PDF]
Nature Communications, 2021 AbstractLight-in-flight sensing has emerged as a promising technique in image reconstruction applications at various wavelengths. We report a microwave imaging system that uses an array of transmitters and a single receiver operating in continuous transmit-receive mode. Captures take a few microseconds and the corresponding images cover a spatial range

Computational polarimetric microwave imaging [PDF]
Optics Express, 2017 We propose a polarimetric microwave imaging technique that exploits recent advances in computational imaging. We utilize a frequency-diverse cavity-backed metasurface, allowing us to demonstrate high-resolution polarimetric imaging using a single transceiver and frequency sweep over the operational microwave bandwidth. The frequency-diverse metasurface

Surface Estimation for Microwave Imaging [PDF]
Sensors, 2017 Biomedical imaging and sensing applications in many scenarios demand accurate surface estimation from a sparse set of noisy measurements. These measurements may arise from a variety of sensing modalities, including laser or electromagnetic samples of an object’s surface.

Microwave Imaging of Cotton Bales [PDF]
Sensors, 2008 Modern moisture restoration systems are increasingly capable of adding water to cotton bales. However, research has identified large variations in internal moisture within bales that are not readily monitored by current systems. While microwave moisture sensing systems can measure average bale moisture, this can be deceptive where water is unevenly ...

Medical Applications of Microwave Imaging [PDF]
The Scientific World Journal, 2014 Ultrawide band (UWB) microwave imaging is a promising method for the detection of early stage breast cancer, based on the large contrast in electrical parameters between malignant tumour tissue and the surrounding normal breast-tissue. In this paper, the detection and imaging of a malignant tumour are performed through a tomographic based microwave ...

Microwave Imaging by Elastic Deformation [PDF]
SIAM Journal on Applied Mathematics, 2011 In this paper, we show that by using microwave measurements at different frequencies and ultrasound localized perturbations to create local changes in the medium it is possible to extend the method developed by Ammari et al. in [SIAM J. Appl. Math., 68 (2008), pp.

Microwave Imaging of the Breast [PDF]
Technology in Cancer Research & Treatment, 2005 Microwave imaging for medical applications has been of interest for many years. Recently, microwave imaging for breast cancer detection has gained attention due to advances in imaging algorithms, microwave hardware and computational power. The breast is relatively translucent to microwaves, accessible for imaging, and there appears to be a significant

Towards microwave imaging of cells [PDF]
Lab on a Chip, 2018 We have simultaneously used the first two modes of a microwave resonant sensor integrated with microfluidics to size and locate droplets and cells. Higher-order modes can yield further spatial details of cells.
