Background
New systems that can reduce errors for image-assisted surgical procedures are desired. At present, tracking errors are frequent due to the tracking systems' sensitivity to the ambient electromagnetic environment. This portfolio addresses these limitations through two essential technologies for image-assisted surgical procedures. Conventionally, these two technologies have never been used together in surgical procedures.
Key Characteristics & Benefits
This patent portfolio discloses an improved system and method for determining the position and orientation of an object in a magnetic resonance scanner by combining electromagnetic position and orientation tracking with magnetic resonance scanning.
- A magnetic field is generated by a magnetic field source, by applying an electric current to a conductive wire loop.
- The magnetic field is measured by a magnetic field sensor, allowing the tracking of the location of the object throughout the field.
- The magnetic field strength is estimated, based on a magnetic field generation and sensing model.
- An error is computed by comparing the estimated magnetic field to the measured magnetic field, and the computation process is then repeated until the error falls below an acceptable level.
- When this level is reached, the location of the sensor based on the estimated location provides a representation of the actual location.
- Further, the magnetic field generation model includes a line segment appropriation accounting for field distorting components.
- When an object is attached to the magnetic field sensor, the location of a pointer which is known by the location tracking device in the reference coordinate frame of the magnetic resonance scanner can be represented in combination with the acquired data from the magnetic resonance scanner.
Market Potential
This is an important strategic portfolio for companies involved in image-assisted surgical procedures.
