ECVT Healthcare System
A radiation-free, real-time 4D imaging platform that maps the electrical activity of living tissue — bringing low-cost, non-invasive detection to the brain and the breast.
The ECVT Healthcare System applies Electrical Capacitance Volume Tomography to the human body, reconstructing the electrical activity of tissue in four dimensions without radiation, contrast agents, or contact with the patient's interior. The system uses the same 32-channel measurement core — established by Warsito, Marashdeh, and Fan (IEEE Sensors Journal, 2007) — that the industrial ECVT platform uses for process imaging, now configured for the dielectric properties of biological tissue.
Because healthy cells, cysts, benign tumours, and malignant cancers each carry distinct dielectric properties and electrical polarities, the system can distinguish between them by how they behave — not only by how they appear. The same imaging core powers two clinical instruments: a 4D brain scanner and a breast cancer scanner.
Used alongside MRI, PET-CT, and mammography, ECVT adds a functional layer that conventional anatomical imaging cannot capture, making it a practical companion for early detection, diagnosis, and treatment monitoring.
The world's first ECVT brain scanner.
A low-cost, radiation-free instrument that detects physiological abnormalities in the brain — those caused by tumours, epilepsy, Alzheimer's disease, and other dysfunctions — instantaneously and in real time.
By imaging cortical and intracranial electrical activity, it opens new possibilities for neuroscience research and clinical neurology alike. Baidillah, Sulaiman, and Aljohani proposed the first real-time volumetric (4D) brain activity imaging system using this sensor — demonstrating observation of both executed movement (EM) and imagined movement (IM) in real time. In 2013, Warsito and Baidillah demonstrated brain tumour detection using ECVT at the IEEE EMBS Conference on Neural Engineering — localising charge accumulation in tumour tissue in both hemispheres and producing volumetric reconstructions of cerebellar structures.
What the brain scanner resolves
Cortical Activity Mapping
Maps electrical activity across the cortical surface. A healthy brain shows high, homogeneous activity; abnormalities appear as low-activity spots against their surroundings.
Intracranial Activity
An average-subtraction method images intracranial electrical activity to instantly surface pain, illness, and pressure-related abnormalities.
Tumour Detection
Localises charge accumulation linked to tumours in either lobe — useful for early detection and for tracking inflammation or seizure-related activity.
3D Real-Time Reconstruction
Renders volumetric 3D images of structures such as cerebellar tumours as the activity unfolds, frame by frame.
Sample imaging
Tracking progress alongside MRI
MRI follows tumour size; ECVT follows the tumour's electrical activity. Together they reveal inflammation and intracranial change during therapy — critical when a tumour sits in a region as delicate as the brainstem.
4D data for studying the brain
Real-time 4D recordings support the study of brain function, response to stimuli, and degenerative or psychiatric conditions — including schizophrenia, Alzheimer's disease, and epilepsy.
Telling cancer apart by how cells behave.
The ECVT Breast Scanner detects abnormalities in the breast by reading electrical activity. Because malignant cancers, benign tumours, simple cysts, and normal tissue each exhibit different dielectric properties and electrical polarities, the system can differentiate between them.
It complements mammography, PET-CT, and MRI with a functional, radiation-free reading of the tissue. Correlation of ECVT permittivity contrast maps against MRI findings and biopsy confirmed that malignant and benign tissue produce distinguishable dielectric signatures. Electrical activity in ECVT correlates with FDG uptake from PET-CT, offering equivalent physiological information without the radiation dose.
What the breast scanner differentiates
Tissue Differentiation
Separates malignant cancer, benign tumour, simple cyst, and normal tissue by their distinct electrical signatures.
Electrical Activity Index
Quantifies activity into an index, giving a comparable measure across malignant cancers, benign tumours, and cysts.
PET-CT Correlation
Electrical activity tracks physiological activity, correlating with the FDG uptake measured by a PET scan — without the radiation dose.
Staging Support
Compared against MRI, ECVT activity reflects both early and advanced development of breast cancers.
