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 methods and systems for image analysis. The method may include obtaining a plurality of image sequences relating to a blood vessel. At least one of the plurality of image sequences may be acquired using a black blood imaging sequence. The method may also include determining a plurality of aligned image sequences by aligning, based on a reference image sequence of the plurality of image sequences, the plurality of image sequences, determining a target region based on the plurality of aligned image sequences, and determining one or more target parameters based on the target region.

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. The method may include determining a segmentation result by segmenting the at least one image using at least one segmentation model. The segmentation result may include at least one target region of the subject in the at least one image. The method may include determining feature information of the at least one target region based on at least one parameter of the at least one target region.

Abstract: The embodiments of the present disclosure provides methods for processing a plaque implemented on at least one machine each of which has at least one processor and at least one storage device for. The method may include: obtaining a plurality of images corresponding to a target vessel; processing the plurality of images; and determining plaque information based on a processing result. The plaque information may include at least one of an identification result of a target plaque, plaque composition distribution, or a detection result of plaque stability.

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 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.
