TEMPERATURE GRADIENT SENSING PROBE FOR MONITORING HYPERTHERMIC MEDICAL TREATMENTS

摘要

Several embodiments of a temperature gradient sensing probe formed from a printed circuit thermocouple array are disclosed. The printed circuit thermocouple array is formed by an eletrically insulative sheet having a first surface, a second surface and N electrically conductive junctions passing through the sheet from the first surface to the second surface, wherein N is an integer greater than one. N electrically conductive paths formed from a first conductive material are applied to the first surface, wherein each of the N conductive paths formed from the first conductive material have a junction end electrically connected respectively to one of the N conductive junctions and a connector end for electrical connection to a signal transmission conduit. N electrically conductive paths formed from a second conductive material, dissimilar to the first electrically conductive material are also provided.
