Title:
局所化および高度に限定された画像再構成法
Document Type and Number:
Japanese Patent JP5737725
Kind Code:
B2
Abstract:
An image reconstruction method includes reconstructing a composite image of a subject using a conventional reconstruction method. The composite image employs the best information available regarding the subject of the scan and this information is used to constrain the reconstruction of a highly undersampled image frames or improve the SNR of image frames. A blurred and normalized weighting image is produced from image frame data, and this normalized weighting image is multiplied by the composite image.
