    摘要： The present disclosure is related to methods and systems for imaging. The method may include obtaining current information of a target subject. The current information may include information relating to current radiation attenuation of the target object. The method may also include obtaining reference information of the target subject. The reference information may include information relating to historical radiation attenuation of the target object. The method may also include determining at least one current parameter of the target subject based on the current information and the reference information. The method may also include obtaining a target image of the target subject based on the at least one current parameter.

    摘要： Embodiments of the present disclosure disclose a method and system for displaying x-ray image, an x-ray machine, and a storage medium. The method includes: obtaining a captured current image of a target region; determining at least one to-be-optimized region in the current image; and for each to-be-optimized region, obtaining a maximum grayscale value and a minimum grayscale value in the to-be-optimized region, determining a window width and a window level for the to- be-optimized region according to the maximum grayscale value and the minimum grayscale value, and displaying the current image based on the window width and the window level. The technical solutions in the embodiments of the present disclosure can improve image display resolution of a current to-be-optimized region.

    摘要： A method for ascertaining an operating parameter of a medical imaging device, the method comprising: providing a measurement dataset by operation of the medical imaging device; and ascertaining the operating parameter as a function of the measurement dataset by a processing algorithm. The processing algorithm includes a sub-algorithm, which provides an intermediate result, wherein the intermediate result depends on a first partial dataset of the measurement dataset, wherein the operating parameter is ascertained as a function of the intermediate result and a second partial dataset of the measurement dataset, and wherein calculation of the intermediate result by the sub-algorithm and the capture of the second partial dataset by the medical imaging device at least partially overlap time-wise.

    摘要： System (SYS) and related method for imaging support. The system comprises an input interface (IN) for receiving an input image (I1) of a patient acquired by an imaging apparatus (IA). The input image was previously assessed by an image quality assessment module (IQM) and was awarded an image quality, IQ, score. The system's imaging triaging module (TL) retrieves from an image database (DBI) of prior assessed images, a corresponding image (I0) that corresponds to the input image. The corresponding image is a prior image of patient. The imaging triaging module (TL) provides a decision, based on the first IQ score and a second IQ score of the corresponding image (I0), if any, whether or not to acquire a new image (I2) of the patient by the imaging apparatus (IA). The risk of unnecessary retakes can be reduced, thus saving time, dose, and reducing wear-and-tear of the imaging apparatus.

    摘要： Provided are an X-ray detector automatically correcting an automatic exposure control (AEC) sensing area, based on an image obtained using an AEC sensor array, and a method of operating the X-ray detector. The X-ray detector may detect, using an AEC sensor array, X-rays that have passed through an object, obtain a one-dimensional (1D) image by quantifying a dose of the detected X-rays into a signal value, identify a symmetric point from the 1D image, based on a signal value for each pixel of the 1D image, and adjust respective locations of a plurality of AEC sensing areas so that the plurality of AEC sensing areas are symmetrical to each other with respect to the identified symmetric point.
