Assessing Patient-Specific Microwave Breast Imaging in Clinical Case Studies
(2021)Microwave breast imaging has seen increasing use in clinical investigations in the past decade with over eight systems having being trialled with patients. The majority of systems use radar-based algorithms to reconstruct ... -
Bilateral 23Na MR imaging of the breast and quantification of sodium concentration
(2014)A novel setup for 23 Na MRI, which allows bilateral imaging of the breast, is presented. For this purpose a figure- eight receive-only 23 Na surface coil was developed. For our experiments on three samples with NaCl ... -
Challenges to Demonstrating Efficacy When Translating Microwave Diagnostic Devices
(2023)Microwave interactions with biological tissues have been proposed and examined for medical diagnostics for over forty years, yet despite substantial academic and industrial interest, very few diagnostic devices are in ... -
Design limitations of using magnetic inductive coupling to verify nasogastric tube placement
(2023)Nasogastric tube insertion is a standard procedure but with potentially fatal consequences if misplaced. Many bedside methods have been proposed for identifying misplace- ment including magnetic inductive coupling. This ... -
Design of a Tetrapolar Probe for Electrical Characterization of the Left Atrial Appendage from 0.1 Hz to 100 kHz
(2022)Recently, non-thermal pulsed-field-ablation using electroporation has generated a lot of interest as a potential treatment for Atrial Fibrillation. The electrical properties, and specially the conductivity of cardiac ... -
Developments in Open-Source Tools for Microwave Breast Imaging
(2024)Open-source models, datasets and toolboxes are becoming increasingly common in the microwave breast imaging literature, including numericial breast models, simulated and experimental datasets and imaging and analysis ... -
Evolving Intelligent Reflector Surface Toward 6G for Public Health: Application in Airborne Virus Detection
(2021)While metasurface-based intelligent reflecting surfaces (IRS) are an important emerging technology for future generations of wireless connectivity in its own right, plans for the mass deployment of these surfaces motivate ... -
FPGA-based Deep-Learning Accelerators for Energy Efficient Motor Imagery EEG classification
(2022)In recent years, Deep Learning has emerged as a powerful framework for analysing and decoding bio-signals like Electroencephalography (EEG) with applications in brain computer interfaces (BCI) and motor control. Deep ... -

The localization of focal heart activity via body surface potential measurements: tests in a heterogeneous torso phantom
(2009)The non-invasive localization of focal heart activity via body surface potential measurements (BSPM) could greatly benefit the understanding and treatment of arrhythmic heart diseases. However, the in vivo validation of ... -
The Me31B DEAD-Box Helicase Localizes to Postsynaptic Foci and Regulates Expression of a CaMKII Reporter mRNA in Dendrites of Drosophila Olfactory Projection Neurons.
(2010)mRNP granules at adult central synapses are postulated to regulate local mRNA translation and synapse plasticity. However, they are very poorly characterized in vivo. Here, in Drosophila olfactory synapses, we present early ... -
The Measurement of Spatially-Dependant Tissue Sodium Concentration Increase in a Rodent MCAO Stroke Model
(2009)The aim of this study was to accurately quantify changes in the Tissue Sodium Concentration (TSC) in the acute phase of a rodent stroke model with high spatio-temporal resolution (0.38mm3 / 10min) at 7T. The ability to ... -
Neurosciences and Wireless Networks: The Potential of Brain-Type Communications and Their Applications
(2021)This paper presents the first comprehensive tutorial on a promising research field located at the frontier of two well-established domains, neurosciences and wireless communications, motivated by the ongoing efforts to ... -

Pathway to Demonstrating Clinical Efficacy of MIcrowave Breast Imaging: Qualitative and Quantitative Performance Assessment
(2022)n 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 ... -
Probe Contact Force Monitoring during Conductivity Measurements of the Left Atrial Appendage to Support the Design of Novel Diagnostic and Therapeutic Procedures
(2022)The electrical properties of many biological tissues are freely available from the INRC and the IT’IS databases. However, particularly in lower frequency ranges, few studies have investigated the optimal measurement protocol ... -
Signal-to-noise ratio of a mouse brain (13) C CryoProbe system in comparison with room temperature coils: spectroscopic phantom and in vivo results.
(2014)MRI and MRS in small rodents demand very high sensitivity. Cryogenic transmit/receive radiofrequency probes (CryoProbes) designed for (1) H MRI of mouse brain provide an attractive option for increasing the performance of ... -
Sodium-23 magnetic resonance imaging during and after transient cerebral ischemia: multinuclear stroke protocols for double-tuned (23)Na/(1)H resonator systems
(2012)A double-tuned 23Na/1H resonator system was developed to record multinuclear MR image data during and after transient cerebral ischemia. 1H-diffusion-, 1H perfusion, 1H T2-, 1H arterial blood flow- and 23Na spin density-weighted ... -
