  • Publication number: 20240281969
    Abstract: A method of analyzing a medical image includes acquiring a correction parameter computed based on a correlation between a first morphological value that is acquired from a first medical image acquired under a first scan condition and is related to a target element, and a second morphological value that is acquired from a second medical image acquired under a second scan condition and is related to the target element. A target medical image is acquired under the second scan condition. A target region related to the target element is acquired by segmenting the target medical image into regions corresponding to elements including the target element. A target morphological value related to the target element is based on voxel data corresponding to the target region. A corrected morphological value is based on the target morphological value and the correction parameter. A morphological index is outputted based on the corrected morphological value.
