AI Technical Summary

Technical Problem

Existing microwave medical imaging systems face challenges with sealing issues, contact with tissues, safety for patients, cleaning, and hygiene, particularly when using liquid or gel transitional materials.

Method used

The system features a hollow cylindrical tank with a vertically movable antennae network, where emission/reception probes are positioned outside the tank, ensuring frank contact without air gaps, and a thermoregulation unit for maintaining stable dielectric properties.

Benefits of technology

This configuration eliminates sealing and hygiene issues, enhances mechanical, thermal, and radiofrequency stability, and optimizes wave propagation for improved image reconstruction.

Abstract

The invention relates to a microwave medical imaging system, comprising: - a hollow cylindrical tank arranged around a vertical axis of revolution XX, the tank being intended to receive a human tissue sample to be observed; - an antenna array placed around the tank, the array being adapted to move vertically along the tank, the antenna array comprising: - an annular antenna support arranged around the tank coaxially with the tank, the antenna support comprising an outer radius and an inner radius defining a ring, the antenna support having several locations formed in angular sectors of the ring, - an assembly of microwave transmitting / receiving probes, each probe comprising a body extending in a location along a radial direction from the ring to the axis XX and a radiating element being disposed at the end of the body and projecting from the support towards the axis XX.the support locations being regularly distributed such that an angular spacing between each probe is constant around the tank, even during the vertical movement of the antenna array along the tank, the support being such that the probes are arranged in the same plane defined by the lower surface of the locations, even during the vertical movement of the antenna array along the tank, the antenna array and the tank being configured and arranged relative to each other so that each radiating element is in contact with the tank, even during the vertical movement of the antenna array along the tank.
