Radar-based microwave imaging has been widely studied for breast cancer detection in recent times. Sensing dielectric property differences of tissues over a wide frequency band this application. We design single- and dual-polarization antennas wireless ultrawideband systems using an inhomogeneous multilayer model the human breast. Antennas made from flexible materials are more easily adapted to wearable applications. Miniaturized monopole spiral on 50-μm Kapton polyimide designed,...
In this work, we present a clinical prototype with wearable patient interface for microwave breast cancer detection. The long-term aim of the is health monitoring application. system operates using multistatic time-domain pulsed radar, 16 flexible antennas embedded into bra. Unlike previously reported, table-based rigid cup-like holder, one requires no immersion medium and enables simple localization surface. comparison prototype, also significantly more cost-effective has smaller footprint....
This study reports on monthly scans of healthy patient volunteers with the clinical prototype a microwave imaging system. The system uses time-domain measurements, and incorporates multistatic radar approach to imaging. It operates in 2-4 GHz range contains 16 wideband sensors embedded hemispherical dielectric radome. has been previously tested tissue phantoms controlled experiments. With this prototype, we scanned 13 patients (26 breasts) over an eight-month period, collecting total 342...
This letter presents an experimental system for microwave breast cancer detection that uses multistatic radar. The operates by transmitting a short-duration pulse and collecting the signals scattered within breast. We describe 16-element array, along with generation scheme, switches, all auxiliary equipment. work provides sample selection of collected time-domain data shows proof concept imaging tumors in realistically shaped phantoms.
Existing treatments for Alzheimer’s disease (AD) have questionable efficacy with a need research into new and more effective therapies to both treat possibly prevent the condition. This review examines novel therapeutic modality that shows promise treating AD based on modulating neuronal activity in gamma frequency band through external brain stimulation. The is roughly defined as being between 30 Hz-100 Hz, 40 Hz point of particular significance. epidemiology, diagnostics, existing...
Background: It is known that proteins associated with Alzheimer’s disease (AD) pathogenesis are significantly reduced by 40 Hz entrainment in mice. If this were to translate humans, verifying such a light stimulus can induce response humans and harnessing insights from these case studies could be one step the development of multisensory device prevent treat AD. Objective: Verify inducement human brain obtain potentially aid for prevention treatment Methods: Electroencephalographic activity...
Despite the significant number of studies published on measurements complex permittivity biological tissues in last thirty years, implementing a successful measurement program for dielectric can still present challenge researchers. Most problems are not theoretical but methodological or practical nature. In this article, lessons learned from experiences with goal-oriented presented by structuring them into guidelines efficient and useful properties tissues, aimed at addressing gaps...
This paper discusses the statistical analysis of dose/cure experiments, developing simplest possible theory in detail with special attention to experimental design and range validity methods advocated. Explanations are aimed at mathematics-tolerant, not mathematician.

We present the design of a flexible multilayer circuit board for use in custom-built microwave system breast health monitoring. The features both an integrated solid-state switching network and 16 wideband antennas, which transmit short-duration pulses into tissues receive backscattered responses. By integrating matrix antenna array on same substrate, we reduce overall cost size comparison with previously demonstrated systems literature. characterize performance using our clinically tested...
In this paper, a new set of tumour phantoms for the experimental evaluation Microwave Breast Imaging (MBI) as method to diagnose breast cancer is presented. The were based on previously developed numerical models that had been clinically validated, supporting appropriateness development systems. proposed phantom was using polyurethane rubber with graphite and carbon-black powders first incorporate large number different shapes levels spiculation emulate malignancy. A series spherical,...
In the last five years alone, there has been an increasing number of operational microwave breast imaging systems used in clinical trials, with increasingly large and diverse patient populations.However, despite this increased activity volume evidence motivating research modality, differences exist how studies evaluate report their findings.In work, qualitative quantitative metrics to measure both image quality effectiveness efficacy are reviewed detail.Image quality, do not have precise or...
The dielectric properties of tissues are the key parameters in electromagnetic medical technologies. Despite apparent simplicity measurement process, reported data have been inconsistent for heterogeneous tissues. Dielectric may be attributed to by identifying tissue types that contributed through histological analysis. However, accurate interpretation measurements with analysis requires first defining an appropriate histology region examine. Here, we investigate multiple definitions probe...
