MRgFUS is a promising non-invasive technique with a wide
range of applications; however, acquiring fully sampled
3D volumetric data with sufficient spatial and temporal
resolution for adequate dose monitoring and guidance is
difficult. Here, we present initial results using a 3D
spiral sequence for MR thermometry and accelerate
imaging in order to improve temporal resolution through
the application of a Kalman filter.
