Abstract: Systems and methods for image processing are provided. The systems may include obtaining an initial image relating to a blood vessel. The system may include determining a centerline of the blood vessel based on the initial image. The system may also include determining one or more images to be segmented of the blood vessel based on the centerline and the initial image. The system may also include determining a boundary of the lumen of the blood vessel and a boundary of the wall of the blood vessel in the each image for each of the one or more images. The system may further include analyzing the blood vessel based on the one or more boundaries of the lumen and the one or more boundaries of the wall.

Abstract: The present disclosure is related to systems and methods for feature information determination. The method may include obtaining at least one image including a subject.

Abstract: The present disclosure relates to methods and systems for vascular image processing. The method may include obtaining an initial vascular image, generating a vascular fragment image by performing a vascular fragmentation operation on the initial vascular image, and generating, based on the vascular fragment image, a vascular centerline image.

Abstract: The present disclosure relates to systems and methods for image processing. The methods may include determining structure data associated with the tissue based on at least one original image of a tissue. The methods may further include determining at least one stenosis region of the tissue based on the structure data associated with the tissue. At least one of the structure data and/or the at least one stenosis region of the tissue may be configured to be displayed on a display device.

Abstract: The present disclosure provides methods and systems for determining information of an ROI of a target subject. The methods may include determining positioning information of the ROI of the target subject by processing first medical imaging data of the target subject using a first determination model. The first medical imaging data may be acquired by performing a first scan with a first field of view (FOV) on the target subject. The methods may include acquiring second medical imaging data of the target subject by performing one or more second scans with a second FOV on the target subject based on the positioning information of the ROI. The methods may further include determining, based on the second medical imaging data, detection information of the ROI.
