Claim 11:
12. A system for determining at least one scanning parameter for a scanning by an imaging device, comprising:
at least one non-transitory storage medium including a set of instructions; and
at least one processor in communication with the at least one non-transitory storage medium, wherein when executing the set of instructions, the at least one processor is configured to cause the system to:
obtain a scout image of at least one portion of a subject;
determine, in the scout image, a region of interest (ROI) corresponding to the at least one portion of the subject; and
determine, based on the ROI, the at least one scanning parameter associated with the at least one portion of the subject for performing the scanning by the imaging device, the at least one scanning parameter including a scanning direction of an axial scanning, wherein the determining, based on the ROI, the at least one scanning parameter, includes:
determining, based on coordinates of pixels in the ROI, a covariance matrix, the covariance matrix indicating a difference between pixels in the ROI in multiple pixel coordinates;
determining, based on the covariance matrix, one or more feature vectors associated with the multiple pixel coordinates;
determining, three feature vectors corresponding to top three highest eigenvalues in the multiple feature vectors, the three feature vectors corresponding to three candidate directions; and
determining, from the three candidate directions, a candidate direction as the scanning direction, the candidate direction forming a smallest angle with a horizontal axis direction among the three candidate directions.
