Abstract: A method for displaying information and an electronic device, wherein the method includes: receiving a new information; acquiring a level of the new information; acquiring a current state of an information display window; and determining a display mode of the new information for displaying the new information according to the level of the new information and the current state of the information display window, wherein the display mode comprises a direct display mode, a waiting in queue mode and a discarding mode. In the embodiments of the disclosure, levels are assigned to information; after a terminal equipment receives a piece of new information, the terminal equipment will no longer directly display the new information, instead, it will determine a display mode based on the information level and the state of the information display window.

Abstract: A method for iterative reconstruction of tomographic images of an object of interest includes obtaining data corresponding to a field of view of a detector, processing the data to prepare a reconstruction support region corresponding to a region within the field of view encompassing the object, and reconstructing a tomographic image using the reconstruction support region. Preferably, the data corresponding to the field of view includes at least one of a projection image of the object, an orbit location of a detector relative to a center of rotation of the detector, or an attenuation coefficient map of the object, which data can be used to describe a reconstruction support region corresponding to the object.
