  • Patent number: 10076249
    Abstract: A system and method for tracking temperature changes in tissue and bone is disclosed. In one aspect, the temperature changes are tracked simultaneously with high spatial encoding and temporal efficiency. The method is robust in terms of B0 and chemical shift off-resonance, as well as insensitive to eddy currents for accurate temperature mapping. Zero TE (ZTE) based MR thermometry is utilized herein to extract temperature changes from proton density and T1 weighted images. Additionally, T1 signal contamination is corrected for by calibrating T1 and B0 by using a variable flip angle method to achieve temperature mapping in bone, aqueous and adipose tissue simultaneously.

  • Patent number: 10076267
    Abstract: Systems and methods for navigation are presented. First and second response signals received from at least one magnetic sensor operatively coupled to a target device in response to a magnetic field are measured at reference and reversed sensitivity while an alignment of magnetic domains corresponding to the magnetic sensor remains unchanged. A useful portion of the first response signal is determined by eliminating common-mode noise from the first response signal based on a difference between the first and second response signals. Alternatively, a bias signal having a desired bias frequency is applied to shift a signal frequency of a response signal of a magnetoresistance sensor that includes common-mode noise. A useful portion of the response signal is determined by measuring the response signal at a shifted frequency that is a sum of the signal and bias frequencies. A position of the subject is then determined based on the useful portion.

The rotatable bowl has a surface operative to support the material bed while the bowl rotates such that particles of the material bed are pulverized against the surface by one or more grinding rollers of the pulverizer mill. The extension ring is disposed about a circumference of the rotatable bowl extending away from the surface and defines a depth of the material bed. The extension mechanism adjusts at least one of the extension ring and the rotatable bowl while the rotatable bowl rotates. Adjusting at least one of the extension ring and the rotatable bowl via the extension mechanism moves the extension ring in relation to the surface so as to adjust the depth of the material bed.
