Abstract: Proposed concepts thus aim to provide schemes, solutions, concept, designs, methods and systems pertaining to updating a magnetic field (B0) map of a subject during a magnetic resonance imaging (MRI) examination or during image reconstruction. In particular, when a subject moves, the magnetic field inside the magnetic bore changes. As a result, any B0 map obtained prior to the movement of the subject may be inaccurate. Accordingly, an initial B0 map is updated to reflect changes in the B0 map caused by the movement of the subject. This can be achieved by determining a B0 map of the subject based on a B0 prediction model, instead of spending additional scanning time to acquire another B0 map.

Abstract: Proposed concepts thus aim to provide schemes, solutions, concepts, designs, methods and systems pertaining to predicting a field perturbation map for magnetic resonance imaging (MRI) of a subject. In particular, the invention aims to provide a field perturbation map of the subject without the need for additional time-consuming scans of the subject. An accurate field perturbation map is necessary in order to obtain an MRI scan of the subject of high quality. Accordingly, a synthetic computed tomography (CT) image is generated by inputting an initial MRI magnitude image of the subject to an image conversion machine learning algorithm. Subsequently, a weighted susceptibility map of the subject is determined based on the synthetic CT image and the initial MRI magnitude image, which is in turn used to determine the field perturbation map of the subject.

Abstract: User interface technologies of an electronic device, including a method of performing one or more actions on an electronic device, are presented. The method comprises selecting at least one item from one or more items displayed on a user interface of the electronic device. The at least one item is selected by touching the at least one item for a predetermined time. After selecting the at least one item, the at least one item is dragged towards one of one or more context based utilities on the user interface. Each of the one or more context based utilities corresponds to a preconfigured action. Then, the at least one item is dropped on the one of the one or more context based utilities to perform corresponding preconfigured action.

Abstract: A method and a device for processing an application of a mobile terminal are provided. The method for processing the application of the mobile terminal includes: generating a display interface, where the display interface includes a user habit list, the user habit list includes at least one user habit option, and the user habit option includes application information and content information; receiving a first operating command input by a user, and determining the user habit option corresponding to the first operating command; triggering an application indicated by the application information of the user habit option which corresponds to the first operating command to parse the content information of the user habit option which corresponds to the first operating command, so as to make the application run content corresponding to the content information.
