Abstract: The present disclosure relates to systems, methods, computing devices, and storage media for medical examination. The medical examination system comprises: a breathing guiding apparatus configured to guide a breathing of a subject; an imaging device configured to scan the subject; and a controller coupled to the breathing guiding apparatus and configured to cause the breathing guiding apparatus to generate a breath guiding state for guiding the breathing of the subject.

Abstract: A hazard point marking method and a hazard point marking system are provided. The method includes: acquiring, by Augmented Reality (AR) glasses, position information of a hazard point in response to a triggering operation of an inspector, where the position information of the hazard point is used for characterizing a position of the hazard point in a tunnel model; sending, by the AR glasses, the position information of the hazard point to a server; and marking, by the server, the hazard point in the tunnel model based on the position information of the hazard point.

Abstract: A method for shielding an inductive sensor includes arranging an annular shielding coil outside an annular detection coil, the shielding coil surrounds the detection coil, and the radial thickness of the shielding coil is smaller than that of the detection coil. An inductive sensor adopting the above method for shielding the inductive sensor, in which the shielding coil is arranged outside the detection coil of the inductive sensor, magnetic fields generated by the two coils are opposite in direction and partially cancel out each other. When interference exists, the magnetic fields generated by the two coils are influenced at the same time and are attenuated or increased by identical strength. Therefore, the summed magnetic field strength can be kept constant, resonance voltages cannot be attenuated, the interference rejection of the inductive sensor is improved, and the sensitivity of the inductive sensor is not influenced.

Abstract: Methods and systems for image processing are provided. A target image may be acquired, wherein the target image may include a plurality of elements, an element of which may correspond to a pixel or a voxel. The target image may be decomposed into at least one layer, wherein the at least one layer may include a low frequency sub-image and a high frequency sub-image. The at least one layer may be transformed. The transformed layer may be reconstructed into a composite image.

Abstract: A system and method for image processing are provided. A pre-processed image may be obtained. The pre-processed image may be decomposed into a low-frequency image and a high-frequency image. At least one grayscale transformation range may be determined based on the low-frequency image. At least one grayscale transformation parameter may be determined based on the at least one grayscale transformation range. The low-frequency image may be transformed based on the at least one grayscale transformation parameter to obtain a transformed low-frequency image. A transformed image may be generated by reconstructing the transformed low-frequency image and the high-frequency image.

Abstract: The present application discloses methods, apparatuses, and systems for acquiring local information to solve the problems of browser instability and difficulty in website maintenance due to the acquisition of local information by using a browser plug-in technology in the prior art. An exemplary method may include sending a first request for information acquisition to a network apparatus through a script in a browser. The first request for information acquisition may be used for instructing a local application tool to acquire local information. The method may also include monitoring, through the local application tool, a random number, sent by the network apparatus, corresponding to the first request for information acquisition.
