A method for extracting vasculature, implemented on at least one machine, each of the at least one machine having at least one processor and a storage device, the method comprising: obtaining an image, the image including a part representing a vessel; obtaining a first image by extracting bone tissue in the image, the first image including the extracted bone tissue, wherein the first image includes a part of the vessel that is extracted as bone tissue including a part of abdominal vessels and/or bone-adjacent vessels; generating a first subtraction image by subtracting the first image from the image, the first subtraction image including at least a portion of the part representing the vessel in the image; obtaining a vessel frame image by extracting vessels from the first subtraction image, the vessel frame image being a part of a target vessel image; and obtaining the target vessel image by performing, to the vessel frame image, at least one iteration of a supplementation with respect to the vessel, wherein each of the at least one iteration of the supplementation includes adding an abdominal vessel image to the vessel frame image, comprising: obtaining a specific bone mask by identifying a specific bone in the image, wherein a distance between the specific bone and the vessel in the image is less than a predetermined threshold; obtaining a bone-vessel mask by segmenting bones and vessels in the image, wherein the bone-vessel mask includes an image of abdominal vessels; obtaining a fifth mask by subtracting, from the bone-vessel mask, the vessel frame image and the specific bone mask; obtaining a sixth mask by segmenting bones in the fifth mask; obtaining a seventh mask by subtracting the sixth mask from the fifth mask; obtaining a first local image by segmenting vessels in the seventh mask; and obtaining the target vessel image by combining the first local image and the vessel frame image. obtaining an image, the image including a part representing a vessel; obtaining a first image by extracting bone tissue in the image, the first image including the extracted bone tissue, wherein the first image includes a part of the vessel that is extracted as bone tissue including a part of abdominal vessels and/or bone-adjacent vessels; generating a first subtraction image by subtracting the first image from the image, the first subtraction image including at least a portion of the part representing the vessel in the image; obtaining a vessel frame image by extracting vessels from the first subtraction image, the vessel frame image being a part of a target vessel image; and obtaining the target vessel image by performing, to the vessel frame image, at least one iteration of a supplementation with respect to the vessel, wherein each of the at least one iteration of the supplementation includes adding an abdominal vessel image to the vessel frame image, comprising: obtaining a specific bone mask by identifying a specific bone in the image, wherein a distance between the specific bone and the vessel in the image is less than a predetermined threshold; obtaining a bone-vessel mask by segmenting bones and vessels in the image, wherein the bone-vessel mask includes an image of abdominal vessels; obtaining a fifth mask by subtracting, from the bone-vessel mask, the vessel frame image and the specific bone mask; obtaining a sixth mask by segmenting bones in the fifth mask; obtaining a seventh mask by subtracting the sixth mask from the fifth mask; obtaining a first local image by segmenting vessels in the seventh mask; and obtaining the target vessel image by combining the first local image and the vessel frame image. obtaining a specific bone mask by identifying a specific bone in the image, wherein a distance between the specific bone and the vessel in the image is less than a predetermined threshold; obtaining a bone-vessel mask by segmenting bones and vessels in the image, wherein the bone-vessel mask includes an image of abdominal vessels; obtaining a fifth mask by subtracting, from the bone-vessel mask, the vessel frame image and the specific bone mask; obtaining a sixth mask by segmenting bones in the fifth mask; obtaining a seventh mask by subtracting the sixth mask from the fifth mask; obtaining a first local image by segmenting vessels in the seventh mask; and obtaining the target vessel image by combining the first local image and the vessel frame image.
