NIRx provides specialized solutions for concurrent fNIRS and fMRI measurements, allowing researchers to leverage the high temporal resolution of optical imaging alongside the superior spatial resolution of the MRI gold standard. These systems are designed to overcome the intrinsic limitations of each individual modality, offering a more comprehensive view of brain hemodynamics. By using MRI-compatible modules and specialized long optical fibers, NIRx enables seamless integration without interference, supporting cross-validation studies and translational research in realistic environments. Supports simultaneous recording of concentration changes in both oxygenated and deoxygenated hemoglobin., Features MRI-compatible optodes and extended optical fibers for safe use within the bore., Offers a modular design that allows for customizable coverage of brain regions., Includes digital trigger inputs to ensure precise synchronization between fNIRS and fMRI data., Robust against motion artifacts, making it an ideal candidate for multi-modal studies., Compatible with both NIRSport2 and NIRScout imaging systems., Facilitates the study of spatial and temporal correlations between the fMRI BOLD signal and optical signals., Non-interfering optical technology ensures that neither modality compromises the data quality of the other.
