Abstract
Medial device comprising a housing, a magnetic detection probe, for detecting a plurality of magnetic fields, a biometric unit and a controller, connected to said magnetic detection probe, said biometric unit and said storage unit, wherein said controller receives magnetic field detection information from said magnetic detection probe, and wherein said controller operates said biometric unit in association with said magnetic field detection information.
Claims47
Apparatus for determining the position and orientation of a surgical tool relative to a reference frame, in association with an image, comprising:
- a magnetic field transmitter, including at least one magnetic field generating element;
- a detection probe including at least one magnetic field detector;
- a signal generation module, connected to said at least one magnetic field generating element;
- a detection processor, connected to said detection probe;
- and
- mounting means, for mounting onto said surgical tool,
- said signal generation module determining a multiple frequency transmit signal and providing said multiple frequency transmit signal to said magnetic field transmitter, said detection processor receiving a detected signal from said detection probe, at least a portion of said detected signal corresponding to said multiple frequency transmitted signal, determining the location and orientation of said detection probe from the power of said at least a portion of said detected signal and indicating the location of said surgical tool within said image.
A medial device comprising:
- a housing
- a magnetic detection probe, for detecting a plurality of magnetic fields;
- a biometric unit;
- and
- a controller, connected to said magnetic detection probe, said biometric unit and a storage unit,
- wherein said controller receives magnetic field detection information from said magnetic detection probe,
- wherein said controller operates said biometric unit in association with said magnetic field detection information.
Method for calibrating a reference image onto a volume, from which the image is produced, the method comprising the steps of:
- determining a plurality of locations in said volume, said locations being visible, said locations being present in said reference image;
- detecting a magnetic field reading in each said locations;
- and
- calibrating said reference image with respect to said magnetic field readings, onto said volume.
Imaging system comprising:
- an inner body ultrasound detector;
- and
- a location and orientation detector, located in proximity of said inner body ultrasound detector,
- wherein said inner body ultrasound detector detects a plurality of two-dimensional images,
- wherein said location and orientation detector detects the location and orientation of each said two-dimensional images.
Method for producing a three dimensional image, comprising the steps of:
- detecting a plurality of two-dimensional ultrasound images, from the inner section of a scanned volume;
- detecting the location and orientation of a selected vector in each said two dimensional ultrasound images;
- and
- determining a three dimensional representation for each said two-dimensional images, according to the location and orientation thereof.
