Abstract: A method to reconstruct images from raw MRI data, and recover an image by solving an optimization problem. Hence, the method is an image reconstruction system for image recovery contrary to similar methods, the method reconstructs all images using both joint and individual objective functions. The method includes: acquiring with the MRI system, multiple images under an influence of different contrast mechanisms, wherein the different contrast mechanisms belong to a same anatomy, solving an optimization problem with an optimization algorithm using both joint and individual objective functions simultaneously for each of multiple image contrasts or a subset of the multiple image contrasts, to reconstruct the multiple images from acquired data.

Abstract: A method for electronic calibration of a magnetic particle imaging system is provided by proposing a coded calibration scene that contains multiple nanoparticle samples distributed randomly or pseudo-randomly inside a volume of the coded calibration scene where nanoparticle positions are changed virtually multiple times to create different calibration scenes. Virtual effect is created with current carrying electromagnets surrounding the nanoparticle samples.

Abstract: A method of calibrating a magnetic particle imaging system including a magnetic field generator and a measurement device by proposing a coded calibration scene, wherein the coded calibration scene contains multiple nanoparticle samples distributed inside a volume of the coded calibration scene, larger than a field of view, wherein the coded calibration scene is moved linearly in one or more directions and/or rotated at one or more axes on the magnetic imaging system, and further, a mechanical system for moving the coded calibration scene.

Abstract: An open bore coil system enabling electronic steering and rotation of a Field Free Line (FFL) inside a large volume. An FFL is generated by placing two parallel coil pairs (fed with alternating current directions) side by side. Using two of these coil groups, the FFL can be rotated in the plane perpendicular to the coil axes. The FFL can be translated in the rotation plane of the FFL using a coil pair placed on the same axis with the other coils. It can also be translated in the perpendicular plane by asymmetrical coil excitation. As all the coils in the system are parallel, the imaged object can be reached from the sides during imaging.
