Electric Capacitance Volume Tomography Analysis
For this type of application scanning or imaging human brain activity used a different approach. A study and experiment had been conducted to real subject in obtaining the real time result and brain mapping of the activity in human brain. Electric Capacitance Volume Tomography (ECVT) were used to measure electrical signals generated from human brain activity and reconstruct volumetric image of the brain signal in real time.
ECVT is a method for determination of the dielectric permittivity distribution in the interior of an object from external capacitance measurements. It predicts the permittivity distribution of an unknown medium based on capacitance measurement between sensor electrodes. Regarding brain activity imaging, however, we are …show more content…
The ECVT sensor system measures the capacitance of electrical signals of the brain on the cortex, and generates a volumetric map of the brain activity on the cortex and inside the brain through a tomography image reconstruction algorithm based on a Neural-Network Multi-criteria Optimization Image Reconstruction Technique
Normal brain function will show that brain signals reach all over the cortical areas as shown in Figure Z. In the ECVT color map, red color indicates high brain activity. The use of ECVT-based brain activity scanner in detecting brain cancer is possible since the presence of tumor will prevent neuro-signal from reaching the cortical areas. Brain tumors prevent neuro-signal propagation to the cortex, causing a certain “brain signal death”, indicated by low activity of the brain on corresponding cortex.
Therefore, the location of brain tumor will be shown as having low activity in the ECVT brain activity map. The ECVT has an advantage over other functional brain imaging techniques since it measures brain electrical signals directly. The ECVT functional brain cancer imaging will provide additional specificity in determining whether an abnormal mass of tissue is a …show more content…
6-10 of the normalized effective permittivity distributions of patients suffering from the brain tumors clearly indicate differences in the brain electrical activity as compared with normal one in Figure Z showing relatively low or no electrical activities of the brain in certain area on the cortices which is closely related to but not exactly the same with the location of the
