A recently granted patent (Publication Number: US11885863B2) discloses a method for reconstructing images in a magnetic resonance imaging (MRI) system. The method involves acquiring multiple images under different contrast mechanisms within the same anatomy and using an optimization algorithm to reconstruct these images from the acquired data. The optimization problem is solved with joint and individual objective functions simultaneously, with the use of analysis-based methods. The patent details the specific calculations and parameters involved in defining the Contrast Total Variation (CTV) and Generalized Sparse (GSp) functions, as well as the incorporation of sensitivity maps for parallel imaging.

Furthermore, the patent outlines the use of various optimization algorithms such as Alternating Direction Method of Multipliers (ADMM), Conjugate Gradient, or Augmented Lagrangian to solve the optimization problem efficiently. The method also considers the employment of total generalized variation (TGV) and 11-norm of a Wavelet transformation as joint and individual objective functions in reconstructing the MRI images. The patent emphasizes the importance of utilizing known sensitivity maps for parallel imaging and updating the transformation matrix accordingly. Overall, the patent provides a detailed and technical approach to image reconstruction in MRI systems, highlighting the significance of optimization algorithms and objective functions in enhancing image quality and accuracy.
