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 accommodate a medium of human tissue to be observed; - an
antenna array placed around the tank, the array being suitable for being moved vertically along the tank, the
antenna array comprising: - an annular antenna support arranged around the tank and coaxially with respect to the tank, the antenna support comprising an outer
radius and an inner
radius defining a ring, the antenna support comprising a plurality of locations formed in angular sectors of the ring; - a set of
microwave transmission / reception probes, each probe comprising a body extending in a location in a radial direction from the ring in the direction of the axis XX, wherein a
radiating element is arranged at the end of the body and projects from the support in the direction of the axis XX, wherein the locations on the support are regularly distributed in such a way that an angular spacing between each probe is constant around the tank, even during the vertical movement of the
antenna array along the tank, wherein the support is 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, and wherein the antenna array and the tank are configured and arranged relative to one another so that each
radiating element is in contact with the tank, even during the vertical movement of the antenna array along the tank.
