Patents by Inventor Alexandre Bigot

Alexandre Bigot has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Thermal therapy with dynamic anatomical boundaries using MRI-based temperature uncertainty maps
    Patent number: 11471053
    Abstract: Temperature uncertainty maps are calculated based on a rolling window of temperature maps, which is updated as new temperature maps are generated. The rolling window mitigates the effect of transient motion during a thermal therapy procedure. A clinician or an automated control system can then update a portion of an anatomical boundary or the thermal therapy applicator center based on the temperature uncertainty map.

  • Method for filtering erroneous pixels in a thermal therapy control system
    Patent number: 11442128
    Abstract: During the delivery of thermal therapy, the measured temperature at each pixel in a cross-sectional temperature slice of a multi-pixel thermal image is compared to a maximum temperature limit. When the measured temperature of a pixel is higher than the maximum temperature limit for a predetermined number of consecutive cross-sectional temperature slices, the pixel is masked if the absolute value of the average difference between the measured temperature at the pixel and the measured temperatures at the pixel's neighbors is greater than a maximum temperature variation. The measured temperature of the masked pixel is ignored in subsequent cross-sectional temperature slices until the delivery of thermal therapy is complete.

  • Processing system and dynamic correction method for thermal therapy
    Patent number: 11191444
    Abstract: In one aspect, a method comprises: receiving data indicative of at least one phase image captured using a magnetic resonance imaging (MRI) device during delivery of thermal therapy by a thermal therapy applicator to a target volume within a patient's body; and processing said at least one phase image; wherein said processing said at least one phase image comprises: applying a first mask; applying phase unwrap; and applying a second mask.
