Biomedical Imaging


ECVT system consists of sensor system, data acquisition system and computer system for control, image reconstruction and display.

ECVT for biomedical imaging are using very low electrical field of less than 15V of voltage source transmitted from the transmitter electrodes, which is highly safe to human body and environmentally friendly. The high speed capability requires only seconds to fully scan the whole objects.

WORLD’S FIRST ECVT Brain - 4D Brain Activity Scanner

WORLD’S FIRST ECVT Brain – 4D Brain Activity Scanner

ECVT Brain, 4D Brain Activity Scanner

ECVT Brain Scanner offers a low-cost, radiation-free, instantaneous detection of physiological abnormalities in the brain caused by tumors, epilepsy, Alzheimer’s Disease and other brain dysfunctions. The technology opens new possibilities for neuroscience researches and other applications.
Electrical Capacitance Volume Tomography (ECVT ) has been applied, for the first time, to image the activity of human brain during different stimulations. Electrical signals measured from capacitance electrodes showed significant differences when the brain is in rest and in high task. The ECVT generates real time and volumetric image of the human brain during the activity, that helps study  of human brain function and possibly detect abnormalities in the brain.

ECVT image of normal brain activity showing high electrical activity on the whole cortical surface of the brain. ECVT image of abnormal brain activity of a patient suffered from brain tumor indicated by the MRI image.







ECVT image is showing low electrical activities of the brain on both the left (especially) and right frontal regions of the brain that are mainly related to visual functions, and both right (especially) and left cerebellum that are related to motoric functions.

 

WORLD’S FIRST ECVT 4D BREAST CANCER SCANNER

WORLD’S FIRST ECVT 4D BREAST CANCER SCANNER

ECVT Breast, 4D BREAST CANCER SCANNER

ECVT requires only seconds, radiation free, to scan whole breast to find abnormalities within the breast caused by malignant cancers, benign tumors or simple cysts without performing biopsy.
The ECVT differentiates malignant breast cancers from benign tumors and simple cysts based on differences in the permittivity value of the reconstructed images. The study shows a demarcation value of maximum normalized permittivity which is regarded as Cell Electrical Activity Index (CEAI) or MALIGNANCY INDEX of 0.3 to classify the malignant cancers from benign tumors and simple cysts. The ECVT is more sensitive to detect malignant cancer than simple cysts or benign tumors.

Mammography and USG are used as golden standards for breast cancer examination in clinical practices, ECVT provides 3D images of the breast in great conformity with the golden standards.
