Research Projects

My research interest includes Electrical Impedance Tomography (EIT) and its applications in biomedical imaging. EIT is a medical imaging tehcnique that images the impedance map of the internal organs of the body. EIT works by injecting small electrical currents into the body through surface-mounted electrodes and measuring the induced voltages on the electrodes. The measured voltages and the applied currents are then used to reconstruct the internal impedance map of the body. Most common application of EIT is imaging the thorax region where the high impedance of the air and relative low impedance of the blood makes EIT a suitable tool to capture the air and blood flow in the lungs.

ACT5 EIT System

The ACT5 EIT system was developed during my Ph.D. studies at Univesity at Albany. ACT5 is a multiple-source applied-current EIT system that can deploy up to 48 electrodes and operated in frequencies between 5 kHz and 500 kHz. It has a frame rates of 27 frames/sec when using 32 electrodes and 54 frames/sec when using 16 electrodes. A sample ACT5 EIT video collected on a saline tank with infinite contrast targets is shown below.
