Embodiment 1

[0068] The embodiment of the present invention provides a data processing method, such as figure 1 As shown, the method includes the following steps:

[0069] 101. Acquire diffusion-weighted imaging image data with different b values, where the diffusion-weighted imaging image data has grayscale information.

[0070] Specifically, DWI image data with different b values ​​can be acquired through MRI imaging technology, where the DWI image data with b value refers to the diffusion-sensitive gradient field parameters applied in the DWI technology.

[0071] 102. Automatically segment a highlighted region according to the grayscale information to determine a cerebral infarction region.

[0072] Specifically, since the grayscale information can reflect the grayscale levels corresponding to different regions of the brain, and since the grayscale levels corresponding to cerebral infarction regions are different from those corresponding to normal brain regions, the brain region can be...

Abstract

The embodiment of the invention provides a data processing method and device. On one hand, the method comprises the following steps that: according to grey information in obtained diffusion-weighted imaging image data of different b values, automatically segmenting a high-lightness area to determine a cerebral infarction area; according to obtained perfusion weighted imaging image data, utilizing an appointed algorithm to obtain perfusion parameter image data; utilizing the perfusion parameter image data and an obtained anatomy map, determining an ischemic area; carrying out image registration on the diffusion-weighted imaging image data and the perfusion weighted imaging image data; and then, on the basis of a registration result, obtaining the mismatching information of the cerebral infarction area and the ischemic area. In the embodiment of the invention, through the above operations, the cerebral infarction area and the ischemic area can be determined, and since a doctor does not need to analyze the perfusion weighted imaging image data or the weighted imaging image data and does not need to manually determine the cerebral infarction area or the ischemic area, duration consumed for confirming the cerebral infarction area and the ischemic area can be shortened.

Description

【Technical field】 [0001] The invention relates to the technical field of medical imaging, in particular to a data processing method and device. 【Background technique】 [0002] DWI (Diffusion weighted imaging, diffusion weighted imaging) image data and PWI (Perfusion weighted imaging, perfusion weighted imaging) image data can be obtained by using MRI (Magnetic Resonance Imaging, magnetic resonance imaging) imaging technology. The judgment of cerebral infarction provides effective imaging information. In the prior art, after obtaining the DWI image data and the PWI image data, the doctor needs to manually mark the DWI image data and the PWI image data respectively to determine the cerebral infarction area and the ischemic area respectively. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] Since the above operation requires the doctor to manually complete the operation of d...
