Systems and Methods for Combined Ultrasound and Electrical Impedance Imaging

Ultrasound imaging provides good spatial resolution and can identify the borders of tissues, and possibly tumors, but the technique is unable to discriminate between benign versus malignant tissue. Electrical impedance imaging ("EII"), on the other hand, is a medical imaging technique that provides information on tissue types and pathologies. EII offers low cost, but also low resolution images. The strengths and weaknesses of ultrasound and EII complement one another such that they may be combined to provide [AH1] images containing tissue characterization information.



Dartmouth inventors have developed systems and methods that combine ultrasound and EII to create 2-D or 3-D tomographic images of tissue. The EII and ultrasound imaging windows are designed to overlap in order to [AH2] facilitate accurate co-registration. In one aspect, an ultrasound probe is integrally formed with an EII electrode array. In another aspect, an EII electrode array may be provided as a modular adapter used to retrofit an existing ultrasound probe.



This technology is claimed in a pending patent application. We are seeking an industrial partner interested in its commercialization.
