  • Patent number: 11074702
    Abstract: Methods for registering a three-dimensional model of a body volume to a real-time indication of a sensor position that involve analyzing scanned and sensed voxels and using parameters or thresholds to identify said voxels as being either tissue or intraluminal fluid.

  • Patent number: 11061093
    Abstract: A dynamic phantom for use with a functional magnetic resonance imaging (fMRI) device is described. In one example, the dynamic phantom includes an outer housing, an inner cylinder including a removable divider, and a gearbox that can rotate the cylinder, all of which are made from fMRI-compatible materials. The divider forms longitudinal compartments inside the cylinder that can each contain a contrast material. When the cylinder contains contrast materials having at least two different concentrations, and a space between the cylinder and the housing also contains a contrast material, rotation of the cylinder produces biomimetic hemodynamic signals that may be detected by the fMRI device.

  • Patent number: 10980421
    Abstract: An electromagnetic tomography system for gathering measurement data pertaining to a human head includes an image chamber unit, a control system, and a housing. The image chamber unit includes an antenna assembly defining a horizontally-oriented imaging chamber and including an array of antennas arranged around the imaging chamber. The antennas include at least some transmitting antennas and some receiving antennas. The control system causes the transmitting antennas to transmit a low power electromagnetic field that is received by the receiving antennas after passing through a patient's head in the imaging chamber. A data tensor is produced that may be inversed to reconstruct a 3D distribution of dielectric properties within the head and to create an image. The housing at least partially contains the antenna assembly and has a front entry opening into the imaging chamber. The head is inserted horizontally through the front entry opening and into the imaging chamber.
