Electric Impedance Assisted Micropipette Aspiration
2007 29th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2007 Micropipette aspiration is a technique to selectively isolate cells from cell cultures using suction pressure. Cells can selectively be isolated one by one from neighboring cells into the micropipette. This paper presents a novel micropipette aspiration system assisted by an impedance measurement system.

Electrical Impedance Tomography
British Journal of Radiology, 1997 Electrical impedance tomography (EIT) is a technique which allows cross-sectional images related to the local electrical impedance within an object to be reconstructed from sets of measurements made on its surface. The main drive behind the development of EIT has been its possible application in medical imaging, as biological tissues are known to ...
