Luminescence Thermometry for Brain Activity Monitoring: A …
2022年7月12日 · Nowadays, preclinical imaging of brain activity is mainly achieved thorough two technologies: - Functional Magnetic Resonance Imaging (fMRI). This technique provides high-resolution images of brain activity by detecting changes associated with blood flow. fMRI is based on the relation between local blood flow and neuronal activation.
We propose BTR as a measurement of dy-namic brain temperature fluctuations in response to a hemody-namic maneuver, hypothesizing the presence of detectable, coherent temperature response differences paralleling tissue-level hemodynamic impairment.
Model-predicted brain temperature computational imaging by …
We introduce a noninvasive, spatially resolved, and optimized mathematical bio-heat model that synergizes model-predicted and MRI-derived data for brain temperature prediction and imaging. Our findings reveal that the brain temperature images generated by our model reflect distinct spatial variations across individual participants, aligning ...
