Abstract: Embodiments of the present application provide a medical imaging method and device. The medical imaging method includes acquiring a scout image of a subject; totaling values of a plurality of pixel points of a pixel row corresponding to each scanning position in a direction of motion of the subject in the scout image, to obtain a projection graph corresponding to the scout image; determining one or more target points in the projection graph; and obtaining a target scanning region in the scout image on the basis of the one or more target points of the projection graph. According to the embodiments of the present application, values of pixel points in a predetermined direction of an image can be totaled to determine a target scanning region, thereby rapidly determining a target edge, foreign objects and the like, so that accuracy of image recognition and efficiency of medical diagnosis can be improved.

Abstract: Provided is a model arrangement information determination method, including: in response to triggering to arrange a first model on a house layout design drawing, displaying at least one capture element of the first model; in response to detecting a drag operation on a first capture element among the at least one capture element, moving the first capture element and the first model according to a trajectory corresponding to the drag operation and a relative position between the first capture element and the first model; and if a preset adsorption condition is met between the first reference line and the first capture element and an arrangement confirmation instruction input by a user is detected during movement, determining an arrangement position of the first capture element based on the first reference line, and determining an arrangement position of the first model based on the first capture element and the first model.
