1. A method for medical imaging, implemented on a computing device having one or more processors and one or more storage devices, the method comprising:
determining, based on personal information of a subject, positioning guidance information;
causing the positioning guidance information to be displayed to the subject;
obtaining a posture of the subject based on first image data of the subject;
generating a first determination result indicating that a positioning procedure of the subject has been finished based on the personal information and the posture of the subject;
generating a second determination result indicating that the subject has remained in a preset static mode or a preset motion mode for a preset time by tracking a motion of one or more feature points or one or more regions of interest of the subject based on second image data of the subject, the first image data and the second image data being a same set of image data or different sets of image data captured by one or more imaging capturing devices, a posture of the subject being unchanged in the preset static mode, and a motion amplitude of the subject being less than a first threshold in the preset motion mode;
prompting the subject to send a starting signal indicating that a scan on the subject can be started based on the first determination result and the second determination result; and
causing the medical device to start performing the scan on the subject after the starting signal of the scan is received.
