Abstract

The invention provides a multi-nuclide magnetic resonance multi-scale image registration method. The method comprises the following steps: step 1, collecting magnetic resonance images of 1H and X nuclides; step 2, selecting a 1H magnetic resonance image as a reference image, and selecting a magnetic resonance image of X nuclide as a floating image; step 3, carrying out feature point extraction on the reference image and the floating image; and step 4, carrying out image registration on the reference image and the floating image by adopting a B spline deformation method. According to the method, characteristic registration is carried out on the 1H image and the X nuclear image (19F, 23Na and 31P) in the multi-nuclide synchronous integrated magnetic resonance scanning image, the calculation method is simple and convenient, and errors caused by manual registration are reduced to a certain extent.

Description

Technical field [0001] The present invention relates to the field of medical image processing, in particular, refers to a method for multi-americen magnetic resonance multi-scale image registration. Background technique [0002] Magnetic resonance imaging (MRI) has an advantage of excellent soft tissue resolution, multi-parameter imaging capability, 3D reconstruction arbitrary aspect and function imaging, play a huge role in early diagnosis and efficacy monitoring of diseases. MRI can provide rich information for the diagnosis of the disease, and there is no disadvantages such as ionizing radiation injury. However, traditional magnetic resonance imaging is mononagne 1 H imaging, including information, unable to reveal the development of the disease from a deeper level. Multikin synchronous integrated chemical imaging provides a multi-molecular event analysis technique for disease mechanism, which can systematically reveal the molecular mechanism in the process of disease developm...
