Abstract: A medical imaging system includes a camera to obtain a captured image including a subject under examination, a display for displaying a graphical user interface including the captured image, and a first boundary indication and a second boundary indication for superimposing and displaying an exposure region on the captured image, an input device for receiving an input operation for adjusting a position of the first boundary indication and an input operation for adjusting a position of the second boundary indication, and a controller for determining the position of the first boundary indication and the position of the second boundary indication according to the input operations received by the input device, and determining a position of an anatomical site. When the position of the anatomical site changes in the captured image, the position of the first boundary indication and the position of the second boundary indication change.

Abstract: The X-ray imaging system includes a camera unit, a display unit, an input unit, an exposure assembly, and a control unit. The camera unit is configured to acquire a real-time optical image of a subject under examination. The display unit is configured to display the real-time optical image. The input unit is configured to receive a user operation and to form a target region on the user interface by changing the position of a center of the collimation region. The exposure assembly includes an X-ray source, a detector, and a collimator, the collimator having an opening configured to display a collimation region on the subject under examination. The control unit is configured to control movement of the X-ray source and the detector to align with the center of the target region, and control the opening of the collimator such that the collimation region is aligned with the target region.

Abstract: A medical imaging system includes an imaging apparatus including an X-ray source and a detector, wherein the X-ray source and the detector are capable of cooperating to acquire a medical image of a subject under examination, and the medical image is formed by stitching a first number of sub-medical images, the first number being greater than or equal to 2, a display apparatus used to display a graphical user interface including a parameter configuration display window, wherein the parameter configuration display window simultaneously displays an exposure parameter for each of the first number of sub-medical images, and a control apparatus used to perform exposure according to a set exposure parameter for the first number of sub-medical images, and to generate the medical image by performing stitching according to the first number of sub-medical images after the exposure.

Abstract: Various methods and systems are provided for automatically registering and stitching images. In one example, a method includes entering a first image of a subject and a second image of the subject to a model trained to output a transformation matrix based on the first image and the second image, where the model is trained with a plurality of training data sets, each training data set including a pair of images, a mask indicating a region of interest (ROI), and associated ground truth, automatically stitching together the first image and the second image based on the transformation matrix to form a stitched image, and outputting the stitched image for display on a display device and/or storing the stitched image in memory.

Abstract: Various methods and systems are provided for x-ray imaging. In one embodiment, a method for an image pasting examination comprises acquiring, via an optical camera and/or depth camera, image data of a subject, controlling an x-ray source and an x-ray detector according to the image data to acquire a plurality of x-ray images of the subject, and stitching the plurality of x-ray images into a single x-ray image. In this way, optimal exposure techniques may be used for individual acquisitions in an image pasting examination such that the optimal dose is utilized, stitching quality is improved, and registration failures are avoided.
