Applications of Current Density Imaging - Page 2 [<<][ < ][ > ][>>]

CDI has been used in the following biomedical studies:

Defibrillation Studies (University of Toronto - Canada)

Researchers and designers of defibrillation systems require more accurate knowledge of current pathways in the chest and heart. A series of CDI measurements in pigs has revealed complex current pathways in this area of the body. [Mike Joy, Dawn Jorgenson, Richard Yoon, Tim DeMonte & Karshi Hasanov]

Burns Caused by Surface-stimulating Electrodes (Aalborg University - Denmark)

Prolonged use of surface electrodes with unbalanced charge pulses leads to skin burns. CDI has been used to verify that these burns exhibit lower impedance that normal skin. Further, it has been demonstrated that CDI may be used to predict the most likely locations of burns before applying the stimulation. Current density 'hot spots' on the skin tend to correlate well with the future locations of burns. [Andrei Patriciu & Ken Yoshida]

Breast Cancer Screening Technique (University of Toronto - Canada)

Current pathways are investigated in a breast phantom model to further substantiate the function of a new impedance measurement based breast cancer screening technique. [Les Organ, Mike Joy, Richard Yoon & Tim DeMonte]

Imaging of Chemical Processes and Reactions (University of Ljubljana - Slovenia)

Conductivity changes were imaged during chemical reactions including dissolving of an ionic solid and formation of an insoluble precipitate. [Katarina Beravs, Alojz Demsar & Franci Demsar]

Imaging Current Density near Deep Brain Stimulator Electrodes (University of Toronto - Canada)

Deep brain stimulator electrodes are implanted in some Parkinson's disease patients to relieve various symptoms. Current density imaging and diffusion tensor imaging are being proposed as two potential imaging techniques that could be used to measure the function and performance of these electrodes in human patients.
