Embodiment Construction
[0019] figure 1 Construct a schematic diagram of a neurofeedback system based on real-time fMRI signals, including:
[0020] (1) The magnetic resonance scanning system, as an acquisition device for brain function signals, outputs the collected magnetic resonance function data in DICOM format in real time by setting a real-time scanning sequence, that is, completes a three-dimensional brain function within the interval time TR of each scanning pulse repetition. Functional data collection, reconstruction and output;
[0021] (2) Real-time data analysis and feedback output, perform format conversion, preprocessing, function positioning detection, and result output processing on the scanned and transmitted data, obtain the brain activation map under the corresponding task, display and identify the activated brain related to the task area; the computer required by the system is required to be able to output at least three video signals, of which two video signals are provided to t...
