    摘要: A method for reducing imaging artifacts includes preprocessing a computed tomography (CT) projection data set to generate preprocessed CT projection data, filtering the preprocessed CT projection data using a mean-preserving filter (MPF) to reduce electronic noise, generating a sinogram using the filtered CT projection data, performing a minus logarithmic operation on the sinogram to generate a noise corrected image, and displaying the noise corrected image on a display. A imaging correcting module and a multi-modality imaging system are also described herein.

    摘要: A portable electronic device includes a first display, a second display, a pivot, and an angle detector. The first display has a first display screen. The second display has a second display screen. The pivot connects the first display and the second display. An angle defined by the first display screen and the second display screen can be changed. The angle detector detects the different angles defined by the first display screen and the second display screen. The portable electronic device has at least two working modes respectively corresponding to the different angles. The portable electronic device automatically switches to a corresponding working mode according the angle detected by the angle detector.
