de Leeuw den Bouter, M.L. (author), van Gijzen, M.B. (author), Remis, R.F. (author)In this paper we present a magnetic resonance imaging (MRI) technique that is based on multiplicative regularization. Instead of adding a regularizing objective function to a data fidelity term, we multiply by such a regularizing function. By following this approach, no regularization parameter needs to be determined for each new data set...journal article 2021

de Leeuw den Bouter, M.L. (author), van Gijzen, M.B. (author), Remis, R.F. (author)We consider the MRI physics in a low-field MRI scanner, in which permanent magnets are used to generate a magnetic field in the millitesla range. A model describing the relationship between measured signal and image is derived, resulting in an ill-posed inverse problem. In order to solve it, a regularization penalty is added to the least...journal article 2019
