AI’s potential for Artificial Phantom Mimicking Tissue of the Human Breast Electrical Properties

National audienceIn this study, we present an assessment method of Early Breast Cancer Detection based on Artificial Intelligence (AI). This method includes prediction, setting and measurement of several human breast phantom mixtures for Microwave Imaging (MWI). These developed Breast Phantoms have realistic dielectric properties (important for Radar Microwave Imaging Systems & Ethical Non-Animal-Testing). We Developed Heterogeneous mimicking tissue architecture for mimicking Breast Tissues (Fat, Regular Fat, Gland, Body Fluid, Blood, Muscle-Tumor, Skin Dry, and Skin Wet) and tested using ultrawideband frequency (0.2 GHz-4.5 GHz) by a modern Vector Network Analyzer. Our qualitative and quantitative research includes the methodology and results for using the material's dielectric parameters and AI algorithms for emulation of real Breast Tissues for Microwave Imaging Pre-clinical trials

NMR planar microcoil for microanalysis

This article deals with the analysis of small sample volume by using a planar microcoil and a micromachined cavity. This microcoil is used as a nuclear magnetic resonance (NMR) radio frequency detection coil in order to perform in vitro NMR analysis of the sample introduced into the microcavity. It is a real challenging task to develop microsystem for NMR spectrum extraction for smaller and smaller sample volume. Moreover, it is advantageous that these microsystems could be integrated in a Micro Total Analysing System ($\mu$-TAS) as an analysing tool. In this paper, NMR theory, description, fabrication process and electrical characterization of planar microcoils receiver are described. Results obtained on NMR microspectroscopy experiments have been performed on water and ethanol, using a 1 mm diameter planar coil. This microcoil is tuned and matched at 85.13 MHz which is the Larmor frequency of proton in a 2 T magnetic field

NMR antenna for an interstitial ultrasound applicator

The aim of this work is to study and design a NMR micro antenna dedicated to ultrasound lesion monitoring by imaging. This micro-antenna will be associated with an oesophageal ultrasound applicator used for oesophagus tumour therapy to provide guidance and monitoring by magnetic resonance imaging (MRI). So, the micro-antenna design was guided by size and shape constraints due to endocavitary applications and adaptation to the ultrasound applicator. In this scope, a coil of N rectangular loops was built. In order to minimise size and offer the ability to perform in vivo adjustments, remote tuning and matching was performed. MRI investigations were carried out using two antennas: a volumic transmitter coil for excitation and this endoscopic receiver coil for signal capture. Lesion can be clearly seen on T2-weighted MR imaging. Lesion measurements on sagittal and axial slices gave a good correlation with lesion dimensions measured on sample
