Systems and methods for 3-D data acquisition for microwave imaging

Tomographic imaging of biological tissue is achieved through a microwave imaging system and associated methods. An array of antennas are positioned in an illumination tank to surround biological tissue to be imaged. A liquid coupling medium is placed in the illumination tank, and the biological tissue is immersed in the medium. The array of antennas transmit and receive microwave-frequency RF signals that are propagated through the biological tissue. A signal processor is coupled to the antennas to process a demodulated signal representative of the microwave-frequency RF signal received by one or more of the antennas to produce scattered field magnitude and phase signal projections of the biological tissue. These projections may be used to reconstruct a conductivity and permittivity image across an imaged section of the biological tissue to identify the locations of different tissue types (e.g., normal versus malignant or cancerous) within the biological tissue. The liquid coupling medium may include glycerol in a solution with water or saline, or in an emulsion with water, and oil and an emulsifier.

3d scanning laser systems and methods for determining surface geometry of an immersed object in a transparent cylindrical glass tank

Systems and methods generate a 3D model of a surface of an object immersed in a transparent liquid within a stationary cylindrical transparent tank. First and second laser line projectors and a camera are rotated around a central axis of the cylindrical tank. The first and second laser line projectors each generate a laser line perpendicular to a plane or rotation and aligned with the center of rotation. The camera images the object. An image from the camera is captured at each of several angular positions of the camera relative to a reference position of the stationary cylindrical tank. The captured images are processed to determine, for each laser line within each image, a plurality of 3D positions where the laser line is incident upon a surface of the object. In embodiments, images are corrected with ray tracing or image warping and registration functions.
