Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] For a fixed voxel point or a fixed region, the change trend of the y=bold(x0, y0, z0, n) function curve reflects the signal change of the point or region during the whole fMRI experiment. Obviously, taking different points or areas will result in different function curves. In the study, the brain area of ​​functional response can be identified by comparing the bold (x, y, z, n) function curves of different regions. The points or areas here are generally selected in the cortical area where the signal is expected to appear, and the selection process is also combined with statistical analysis methods.

[0031] (1) Create a new analysis database: Before analyzing the data, a new analysis data sub-database should be established. Enter data into a database and analyze it using the database.

[0032] (2) Data import: Import the data to be analyzed from the file into...

Abstract

The invention discloses a data analyzing method based on an fMRI brain activation data warehouse. The method includes the following steps that a basic framework of the fMRI data warehouse is built, data extraction is carried out, and dimensions and a fact table are introduced; data processing and multi-dimensional analysis are carried out. Basic principles and technologies of the data warehouse are used for secondary processing of data in brain activation researches, and a multi-dimensional analysis technology is introduced into analysis and processing of result data of brain activation, so that secondary analysis, processing and integration can be carried out, new rules are found, and deep mechanisms of advanced brain activities are disclosed. Accordingly, scattered brain function imaging data and results in the prior art can be used orderly.

Description

technical field [0001] The invention relates to a data analysis method that introduces data warehouse and data mining technology into a data warehouse based on fMRI brain activation, and belongs to the field of medical image processing. Background technique [0002] With functional Magnetic Resonance Imaging (fMRI), the changes of the signal can be tracked in real time. For example, thinking activities that occur in only a few seconds, or changes in signals in cognitive experiments, the time resolution reaches 1s. With the continuous maturity and development of this technology, more and more scholars use fMRI to study the high-level neural activities of the brain. fMRI has greatly enhanced our ability to conduct brain research. In recent years, it has been widely used in the study of brain functions such as perception, motor control and language cognition, and these research activities have also generated a large amount of experimental data. SPM is specially designed for t...
