AI Technical Summary
In existing technologies, EEG and NIRS devices have low spatial and temporal resolution and are susceptible to external electrical interference. The integration of multimodal brain imaging systems is difficult, resulting in insufficient and inaccurate monitoring of brain function and structural information.
A multimodal synchronous brain imaging system based on nuclear magnetic resonance-optical-electricity was designed, integrating a PET-MR device, an EEG device, a detector headgear, and an eye tracker. The system provides a synchronization signal through a clock source within the MR device, enabling the synchronous acquisition of five modalities, including PET, MR, EEG, NIRS, and eye tracking. A high-resolution 64-channel head coil and a modular layout are employed to reduce signal interference and achieve efficient data fusion.
It improves the comprehensiveness and accuracy of brain imaging, enabling the simultaneous acquisition of high-resolution neural structure and molecular-level information, enhancing the precision and timeliness of brain function detection, and supporting early diagnosis and neuroscience research.
