  • Patent number: 11513178
    Abstract: The invention relates to an MRI apparatus and a method of MRI involving the acquisition of a first and a second MRI image with mutually different orientations between the BO magnetic field and the object to be investigated. For instance, when imaging structures such as a tendon, due to the magic angle effect, this results in a change in image contrast. According to the invention, a coregistration can be performed between the first and the second MRI image. Moreover, the orientation of a structure within the object can be determined on the basis of the different orientations and the image intensity in the first and the second MRI image. The invention further discloses an apparatus for carrying out the method and a method of shimming the BO magnetic field of the apparatus.

  • Patent number: 11108206
    Abstract: Masing at room temperature is achieved by an apparatus and method that utilize a microwave cavity which exhibits a resonance of sufficiently high Q-factor for maser oscillation, and a resonator structure comprising a masing medium located within a resonant element. The masing medium comprises spin-defect centres. The resonator structure is disposed within the microwave cavity. A magnetic field is applied across the masing medium. An input of microwave radiation to be amplified is coupled to the resonator structure. An optical pump pumps the masing medium, thereby causing stimulated emission of microwave photons. The microwave cavity has an effective magnetic mode volume matching the volume of the masing medium.

  • Publication number: 20210257051
    Abstract: This disclosure relates to methods, systems, computer programs and computer-readable media for the multidimensional analysis of real-time amplification data. A framework is presented that shows that the benefits of standard curves extend beyond absolute quantification when observed in a multidimensional environment. Relating to the field of Machine Learning, the disclosed method combines multiple extracted features (e.g. linear features) in order to analyse real-time amplification data using a multidimensional view. The method involves two new concepts: the multidimensional standard curve and its ‘home’, the feature space. Together they expand the capabilities of standard curves, allowing for simultaneous absolute quantification, outlier detection and providing insights into amplification kinetics.
