A modeling system is presented that can be used to predict the effects of ventilatory settings on the blood gases of patients on mechanical ventilation. The system uses a physiological model of the patient that includes lungs, body tissue, and brain tissue compartments. The model includes the effects of changes in the cardiac output and cerebral blood flow and lung mechanical factors. The system has...
The emerging functional MRI (magnetic resonance imaging), fMRI, imaging modality was developed to obtain non-invasive information regarding the neural processes behind pre-determined task. The data is gathered in such a way that the extraction certainty of the desired information is maximized. Still this is a difficult task due to low Signal-to-Noise Ratio (SNR), corrupting noise and artifacts from...
With the recent development, magnetic resonance imaging went beyond the anatomical and morphological imaging and gave information about physiological properties of the tissues. Anatomical images with high resolution could be get by MRI using a combination of rapid imaging techniques and bolus injection of extracellular contrast agents. Perfusion weighted MRI (PWI) has been used in clinical practices...
This research is aimed at integrating two-dimensional (2-D) optical topographic maps to anatomical magnetic resonance imaging (MRI) for 3-D functional brain mapping. The uniqueness of this approach is in mapping topographic maps to the cortex surface of the brain based on projections of the results obtained from the skull surface. MRI is known to provide information about the anatomical structure...
