Lung imaging in certain conditions, such as patients with Acute Respiratory Distress Syndrome (ARDS), poses its challenges. Heterogeneity of lung damage ARDS can only be detected by CT scan, causing treatment delay and increased mortality. Difficulty to perform standard CXR also contributes the increasing incidence VALI (Ventilator-Associated Injury) due diagnosis delay. EIT (Electrical Impedan...

Magnetic Resonance Electrical Impedance Tomography (MREIT) is a relatively new imaging technique that allows tomographic imaging of electrical conductivity of biologically conductive objects. In this paper, we present software that has been implemented to accompany MREIT. The software offers various computational tools from preprocessing of MREIT data to reconstruction of crosssectional conduct...

The origin of electrical burns under gel-type surface electrodes is a controversial topic that is not well understood. To investigate the phenomenon, we have developed an excised porcine skin+gel model. In the present paper, we describe methods to detect these burns in the skin+gel model in an effort to understand the genesis of these burns. Burns were induced by severe electrical stimulation a...

This paper reviews the latest impedance imaging technique called Magnetic Resonance Electrical Impedance Tomography (MREIT) providing information on electrical conductivity and current density distributions inside an electrically conducting domain such as the human body. The motivation for this research is explained by discussing conductivity changes related with physiological and pathological ...

Imaging of neuronal depolarization in the brain is a major goal in neuroscience, but no technique currently exists that could image neural activity over milliseconds throughout the whole brain. Electrical impedance tomography (EIT) is an emerging medical imaging technique which can produce tomographic images of impedance changes with non-invasive surface electrodes. We report EIT imaging of imp...
