Abstract
An electromagnetic (EM) tomography head scanner comprising an antenna chamber, a radio frequency and microwave circuit, a control and monitoring unit, and a signal processing unit and an artificial intelligence unit.
Claims17
An electromagnetic head imaging system comprising:
- an antenna chamber shaped to receive a subject head;
- a plurality of sensor assemblies disposed within the antenna chamber, each sensor assembly movable around at least a portion of the subject head to be positioned opposite to another sensor assembly, each sensor assembly comprising at least one antenna;
- at least one processor configured to:
- move at least one sensor assembly of the plurality of sensor assemblies to a series of different positions around the subject head;
- at each position of the series of different positions around the subject head, obtain electromagnetic field measurements at at least one pair of opposing sensor assemblies;
- and
- determine scattering parameters based on the electromagnetic field measurements obtained from the at least one pair of opposing sensor assemblies in each position of the series of different positions around the subject head;
- and
- generate an image of the subject head based on the scattering parameters associated with the series of different positions around the subject head;
- and
- at least one arm, one or more sensor assemblies of the plurality of sensor assemblies being disposed on each arm of the at least one arm, each arm of the at least one arm being movable to move the one or more sensor assemblies disposed thereon;
- wherein the subject head defines a longitudinal axis, and the system further comprises:
- at least a first motor operable to adjust a roll angle of the at least one arm about the longitudinal axis and a second motor operable to adjust a pitch angle of the at least one arm about the longitudinal axis;
- and
- a rail mechanism within the antenna chamber, the at least one arm being moveably coupled to the rail mechanism, the one or more sensor assemblies disposed on the at least one arm moving radially about the longitudinal axis when the at least one arm moves along the rail mechanism.

A method of generating an electromagnetic image of a subject head, the method comprising:
- receiving the subject head within an antenna chamber;
- moving at least one sensor assembly of a plurality of sensor assemblies to a series of different positions around the subject head, wherein the at least one sensor assembly is disposed on at least one arm and the subject head defines a longitudinal axis, and wherein at least a first motor operates to adjust a roll angle of the at least one arm about the longitudinal axis and a second motor operates to adjust a pitch angle of the at least one arm about the longitudinal axis;
- and
- operating at least one processor to:
- obtain electromagnetic field measurements at at least one pair of opposing sensor assemblies when the at least one sensor assembly is at each position of the series of different positions around the subject head;
- determine scattering parameters based on the electromagnetic field measurements;
- and
- generate an image of the subject head based on the scattering parameters associated with the series of different positions around the subject head.
