Abstract
The present invention provides an apparatus and method for detecting and predicting shape and underlying object properties. In accordance with an aspect of the present disclosure, there is provided an imaging apparatus having: an array of at least three co-planar electromagnetic transceiver defining a receiving plane; at least one deformable electromagnetic transceiver moveable orthogonally to the receiving plane; a two dimensional (2D) position tracking device configured to track a position of the electromagnetic transceiver on a surface 110 bounding a volume to be imaged; wherein the electromagnetic transceivers are configured to generate data from at least three depths below the surface for use in creating an image of the volume when the apparatus is moved along the surface.
Core Innovation
The invention relates to an apparatus for detecting and monitoring intracranial fluid in a subject. The apparatus uses three fixed contact points configured to contact a curved surface bounding a volume to be imaged, and an array of at least three co-planar electromagnetic transceivers defining a receiving plane. At least one deformable electromagnetic emitter is moveable orthogonally to the receiving plane and to the plane defined by the three fixed contact points, and the emitter is configured to contact the curved surface bounding the volume to be imaged.
A two-dimensional (2D) position tracking device tracks the position of the apparatus in x-y coordinates while moving on the curved surface. A displacement sensor measures deformation of the deformable electromagnetic emitter as it moves on the curved surface. The electromagnetic emitter and transceivers generate optical density data relating to presence or absence of intracranial fluid from at least three depths below the curved surface, for use in creating an image of the volume as the apparatus is moved along the curved surface.
Local curvature of the curved surface is determined by orthogonal displacement of the deformable electromagnetic emitter relative to the plane defined by the three fixed contact points, and the local curvature is correlated to the position of the apparatus as measured in x-y coordinates. The curvature and position correlation is used to support creation of tomographic, multi-depth images of a volume as the apparatus is moved along the curved surface.
Claims Coverage
Independent claim clm-00001 defines an apparatus with eight inventive features: three fixed contact points for plane definition on a curved surface, a co-planar electromagnetic transceiver array receiving plane, an orthogonally deformable electromagnetic emitter with a displacement sensor, 2D x-y position tracking, multi-depth optical density data generation, and local curvature determination correlated to x-y tracked position for image creation.
Three fixed contact points for curved surface plane definition
The apparatus comprises three fixed contact points defining a plane, each contact point configured to contact a curved surface bounding a volume to be imaged.
Co-planar electromagnetic transceiver array receiving plane
The apparatus includes an array of at least three co-planar electromagnetic transceivers defining a receiving plane.
Orthogonally deformable electromagnetic emitter contacting curved surface
The apparatus includes at least one deformable electromagnetic emitter moveable orthogonally to the receiving plane and the plane defined by the three fixed contact points, wherein the deformable electromagnetic emitter is configured to contact the curved surface bounding the volume to be imaged.
2D x-y position tracking while moving on curved surface
The apparatus includes a two-dimensional (2D) position tracking device configured to track a position of the apparatus in x-y coordinates while moving on the curved surface bounding the volume to be imaged.
Displacement sensor measuring emitter deformation
The apparatus includes a displacement sensor configured to measure deformation of the at least one deformable electromagnetic emitter moving on the curved surface.
Multi-depth optical density data for image creation during movement
The electromagnetic emitter and transceivers are configured to generate optical density data relating to presence or absence of intracranial fluid from at least three depths below the curved surface, wherein the optical density data is for use in creating an image of the volume as the apparatus is moved along the curved surface.
Curvature determined by orthogonal emitter displacement relative to fixed contact plane
Local curvature of the curved surface is determined by orthogonal displacement of the deformable electromagnetic emitter relative to the plane defined by the three fixed contact points.
Correlation of local curvature to x-y tracked apparatus position
Local curvature of the curved surface is correlated to the position of the apparatus as measured in x-y coordinates.
Across the independent claim, the apparatus detects and monitors intracranial fluid by generating optical density data from multiple depths while using three-point plane contact, a co-planar transceiver receiving plane, an orthogonally deformable electromagnetic emitter with a displacement sensor, and 2D x-y tracking. Local curvature determined from orthogonal emitter displacement is correlated to the x-y position to support image creation as the apparatus moves along the curved surface.
