Abstract: A man-in-the-middle detection method and apparatus. The method includes: A base station receives, in a first physical frame, a RRC message from user equipment UE; the base station receives from the UE a second RRC message including frame information of a second physical frame, and security protection is performed on the first RRC message and the second RRC message by using an access stratum AS security context established by the UE and the base station; and the base station determines whether the first physical frame matches the second physical frame.

With a single-kVp source, the absorption grating can also be omitted and the filter grating can remain stationary.

Abstract: Novel and advantageous systems and method for obtaining and/or reconstructing simultaneous computed tomography (CT)-magnetic resonance imaging (MRI) images are provided. Structural coupling (SC) and compressive sensing (CS) techniques can be combined to unify and improve CT and MRI reconstruction. A bidirectional image estimation method can be used to connect images from different modalities, with CT and MRI data serving as prior knowledge to each other to produce better CT and MRI image quality than would be realized with individual reconstruction.

An iterative reconstruction algorithm can be used to reconstruct an improved image, and then the improved image can be used to adjust inaccurate parameters by using a Locally Linear Embedding (LLE) method. Adjusted parameters can then be used to reconstruct new images, which can then be used to further adjust the parameters. The steps of this iterative process can be repeated until a quality threshold is met.
