Inventions
Inventions from my work on wire-free localization of breast lesions. All applications are pending; each number links to the full document on Google Patents.
A neural network estimates a magnetic marker’s position and orientation from the probe’s magnetic-field-gradient readings. Comparing the gradients that estimate should produce with the gradients actually measured reveals magnetic interference, so the system can flag spurious fields.
A handheld probe with three multi-axis magnetometers staggered along its substrate, on opposite faces and with non-collinear measurement axes, from whose signals a processor determines the position and orientation of an implanted magnetic marker.
A probe for locating an anisotropic (for example cylindrical) permanent-magnet marker of known size, shape and magnetization: three multi-axis magnetic sensors on both sides of a substrate, offset along and across it, let a processor compute the marker’s position and pose in five degrees of freedom.
Locates an implanted fiducial marker or soft-tissue lesion by analyzing the raw RF echo data from an ultrasound transducer array (for example with filtering and a machine-learning classifier), then shows the surgeon the target’s distance and direction.
