Abstract: A method, an apparatus, an electronic device and a storage medium for displaying an AR navigation are provided. The method may include: recognizing a navigation scene at a current moment during an AR navigation; determining, according to a preset mapping relationship between a navigation scene and a service function, a current service function corresponding to the navigation scene at the current moment; and displaying the current service function corresponding to the navigation scene at the current moment in the navigation scene at the current moment. According to embodiments of the present disclosure, different service functions may be flexibly displayed for different navigation scenes. Therefore, a multi-channel output in the different navigation scenes may be realized, thus saving maintenance time and a maintenance cost.

Abstract: A method for reconstructing a PET multi-bed image is provided, which may be applied to a PET scan having an axial overlapping region existed between every two adjacent beds. According to an example of the method, a combined set of PET projection data for at least two beds may be obtained by combining a set of PET projection data for at least two successive beds together in such a manner that two sets of PET projection data corresponding to an axial overlapping region between every two adjacent beds are added up. And then, a PET image for at least two beds may be reconstructed based on an image reconstruction iteration model and the combined set of PET projection data for the plurality of beds.
