Brain ECVT System
Images: Brain Cortical Electrical Activity generated by ECVT for normal as well as abnormal activity of the cortical area. The cortical activity map correlates with brain function, showing relatively high and homogeneous electrical activity on the whole cortical surface of the brain for normal brain. Abnormalities in the brain functions are showed by spots with relatively low activity as compared to the surroundings.
Images: Intracraniall brain electrical activity generated by ECVT using average substraction method to instanly detect pain, illness and other abnormalities. The electrical activity corresponds to electrical charge distribution that correlates to intracranial pressure.
Images: Intracraniall brain electrical activity generated by ECVT can be used to detect illness or abnormalities caused by tumors: tumor in the right lobe of the brain (LEFT) and tumor in the left lobe of the brain (RIGHT); The images obtained by ECVT may be usefull to early detect possibility of tumor development or monitoring of the progression of llness related to tumors such as inflammation development or high electric charge accumulation that could cause seizure.
Images: LEFT: Monitoring of treatment of GBM in the brainstem treated with ECCT using ECVT in conjunction with MR; While MRI images showed significant tumor shrinkage in the size in the first 1.5 year, and relatively no change afterward, the electrical activity of the brain taken by ECVT showed remarkable change from relatively low activity, then increased dramatically during the first month of the treatment and then decreased gradually back to normal. The electrical activity indicates a process of inflammation in the tumor area may be caused by the process of cancer destruction due to the treatment which extremely important to monitor especiall as the to tumor is in the crucial area of the brainstem; RIGHT: Brain ECVT scan of the cortical electrical activity map shows disappearing low activity area caused by the tumor with the progress of the treatment; The electrical activity of the brain becomes normal with the treatment progress.
Images: While MRI generates accurate image of the brain to detect the tumor, ECVT images electrical activity of the brain that corresponds to intracranial pressure related to the tumor. The image fusion may be useful to accurately map functionally illness caused by the tumor.
Images: 4D ECVT images and signal data during different stimuli.
Images: ECVT images of brain electrical activity of schizophrenia case, showing highly unregulated and fastly changing patterns; while corresponding images of MRI showing no abnormality.
Images: Brain ECVT electrical activity of Alzheimer Disease case, as compared to corresponding PET-CT scan images.
