Abstract: A keypoint detection method is provided for medical imaging, a medical imaging method and a medical imaging system. The keypoint detection method for medical imaging includes: receiving an image sequence, the image sequence comprising a plurality of images of an object; performing keypoint detection on the plurality of images separately, and generating a keypoint image sequence; performing keypoint occlusion detection on the images in the image sequence; and determining keypoint distribution information according to the keypoint image sequence and a result of the keypoint occlusion detection.

Abstract: A method and apparatus for determining the orientation of a subject during medical imaging, and a medical imaging system is provided. The method includes: acquiring an image sequence of a subject captured by a camera, the image sequence comprising a plurality of images based on a time sequence; determining, based on the image sequence, whether the state of the subject is abnormal; and in response to a determination result that the state of the subject is abnormal, determining the orientation of the subject by using a first orientation or a second orientation, wherein the first orientation is the orientation of the subject determined based on an image before a period when the state of the subject is determined to be abnormal, and the second orientation is the orientation of the subject determined based on an image after the period when the state of the subject is determined to be abnormal.

Abstract: Provided in embodiments of the present application are an occlusion detection method for medical imaging, a medical imaging method, and a medical imaging system. The occlusion detection method for medical imaging includes: acquiring an image sequence, the image sequence including a plurality of images of an object in a time dimension; and according to at least one among confidence level change information and depth change information of a keypoint of the object in the plurality of images, determining an occlusion state of the keypoint.
