1. A method, comprising the steps of:
- identifying a target tissue area;
placing a first electrode and a second electrode such that the target tissue area is positioned between the first electrode and the second electrode;
applying a pulse of current between the first electrode and the second electrode; and
creating an image of an area of the target tissue between the first electrode and the second electrode.

Abstract
A method and a system for producing the method are disclosed whereby irreversible electroporation pulses are produced across an area of target tissue. A medical imaging device is used to create an image of the irreversible electroporation in real time thereby making it possible to determine the area of electroporation and the extent of results obtained and to adjust the positioning of electrodes and/or the current as needed based on the image being viewed.

15. A method of irreversible electroporation comprising the steps of:
-
(a) identifying a target tissue area;
(b) placing a monitoring device into the tissue in the area of the identified target tissue;
(c) placing electrodes in a manner such that the identified target tissue area is positioned between the electrodes;
(d) applying a test current which test current is insufficient to cause irreversible electroporation;
(e) monitoring the test current effects on the target tissue and at a remote location;
(f) extrapolating back based on the amount of the test current to determine an amount of current necessary to achieve irreversible electroporation; and
(g) applying current so as to obtain irreversible electroporation. - View Dependent Claims (16)
