Embodiment 1

[0086] The embodiment of the present invention proposes a method for constructing a clinical brain CT image ROI template, such as figure 1 As shown, the method includes the following steps:

[0087] Step 110, acquiring the brain CT image I of the same individual in the same state CT_0 and MRI images I MRI_0 .

[0088] CT images and MRI images of the same individual in the same state have similarities in brain functional areas. The acquired CT images and MRI images need to be preprocessed and cropped to the same size. A digital image can be represented by a numerical matrix. Computers usually use a two-dimensional array to store image data. The elements of the matrix correspond to the pixels of the image, and the value of the matrix elements is the gray value of the pixel.

[0089] Step 120, for the MRI image I MRI_0 ROI template image I obtained by marking ROI in the region of interest MRI_ROI , and get the ROI labeled image I ROI .

[0090] In medical images, image us...

Embodiment 2

[0155] Corresponding to the above-mentioned embodiment 1, the embodiment of the present invention proposes a system for constructing a clinical brain CT image ROI template, such as figure 2 As shown, the system includes:

[0156] Image acquisition module 210, used to acquire brain CT images I of the same individual in the same state CT_0 and MRI images I MRI_0 ;

[0157] Image processing module 220, for MRI image I MRI_0 ROI template image I obtained by marking ROI in the region of interest MRI_ROI , and get the ROI labeled image I ROI ;

[0158] According to CT image I CT_0 and MRI images I MRI_0 , to obtain the braincase mask map I of the CT image respectively CT_1 And the brain case mask map I of the MRI image MRI_1 ;

[0159] Braincase mask map I for CT images CT_1 Braincase mask and MRI image I MRI_1 Mark the contour of the braincase and obtain the mask map M of the contour of the braincase of the CT image CT_1 and the braincase contour mask of the MRI image...

Abstract

The embodiment of the invention discloses a method and system for constructing a clinical brain CT image ROI template. Obtaining the similarity of the brain functional areas of the CT image and the MRI image of the same individual; an ROI template based on an MRI image is used; a series of multi-step single-mode rigid and non-rigid registration is carried out; the ROI template based on the CT image is manufactured, the purpose of multi-mode registration is achieved by utilizing the theoretical basis of single-mode registration, the registration precision is high, the problem that the precisionis low due to the fact that multi-mode registration is directly used is solved, and the manufactured ROI template for the CT image can be used for clinical practical application.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of medical imaging, and in particular to a method and system for constructing an ROI template of a clinical brain CT image. Background technique [0002] With the continuous development of medical imaging technology, more and more imaging methods have emerged, and are widely used in the research of brain cognitive function and medical clinical diagnosis and treatment. Due to the different imaging principles and equipment, computer-aided tomography (CT) and magnetic resonance imaging (MRI) are commonly used clinically. These two types of imaging methods have their own advantages and disadvantages, and the information they provide are not exactly the same. For example, in structural imaging, CT can clearly display the structural images of bones, while MRI is more suitable for soft tissue morphology imaging. Therefore, different modalities of imaging Methods can provide complementary info...
