Title:
事前情報に制約される正則化を使用するＭＲ画像再構成
Document Type and Number:
Japanese Patent JP6513398
Kind Code:
B2
Abstract:
The invention relates to a method of MR imaging of at least a portion of a body (10) of a patient placed in an examination volume of a MR device (1), the method comprising the steps of:
- subjecting the portion of the body (10) to a first imaging sequence for acquiring a first signal data set (21);
- subjecting the portion of the body (10) to a second imaging sequence for acquiring a second signal data set (23), wherein the imaging parameters of the second imaging sequence differ from the imaging parameters of the first imaging sequence;
- reconstructing a MR image from the second signal data set (23) by means of regularization using the first signal data set (21) as prior information. Moreover, the invention relates to a MR device (1) and to a computer program for a MR device (1).
