Abstract

The invention relates to a medical imaging system having microwave emitting antennas and antennas for receiving the electromagnetic field, which are arranged around a space for receiving a human tissue medium to be observed, and comprising: an array (3) of emitting antennas and an array (4) of receiving antennas, wherein said two arrays (3, 4) are independent, and motors capable of angularly rotating and of translating the emitting array (3) and/or the receiving array (4) relative to the space under observation, in order to enable the scanning thereof.

Dependent claims

A medical imaging system with microwave transmission antennas and antennas of reception of the electromagnetic field arranged around a volume intended to receive human tissue medium to be observed, characterized in that it comprises:

a shell (1) defining the volume intended to receive human tissue medium to be observed, the shell (1) having an external form, the external form of the shell (1) being symmetrical in rotation around a vertical axis, the shell (1) being made of solid dielectric material;
an array (3) of transmission antennas (3a) and an array (4) of reception antennas (4a) for microwave imaging, these two arrays (3, 4) being independent, the antennas (3a) of transmission and the antennas (4a) of reception directly coupled to supports (3b, 4b), wherein each of the supports comprise material of dielectric permittivity identical to that of said shell (1);
and
one or more motors capable of shifting at least one of the transmission array (3) and the reception array (4) relative to the shell (1) in angular rotation around the vertical axis and in translation along the vertical axis to enable scanning of the volume under observation, the two arrays (3, 4) being independent in rotation and translation, the rotation and the translation of each array being independent.
