A method and apparatus for removing tissue from a volume surrounding a region of interest with a body part of a patient is disclosed. The tissue removal volume and location is determined by stereotactic radiography. The size of the tissue removal volume surrounding the region of interest is derived by placing boundaries around the region of interest in each stereotactic radiographic image. A tissue removal tool is moved within the derived tissue removal volume. The tissue in the region of interest which has been previously diagnosed as cancerous can be marked with a radioactive isotope, for example, and the removal of such tissue from the removal volume which surrounds the region of interest can be monitored to determine whether the tissue in the region of interest has been completely removed.

Method and apparatus for removing tissue from a region of interest using stereotactic radiographic guidance

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 electrically 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. The N conductive paths formed of the second material have a junction end electrically connected to one of the N conductive junctions and a connector end for electrical connection to a signal transmission conduit. The array may be applied to a shaft or disposed within a tube to form the probe. The N conductive paths formed of a second material may be replaced by a single, common conductive path formed of the second material which is connected to the conductive junctions. A panel connector for the probe is also disclosed.

Temperature gradient sensing probe for monitoring hyperthermic medical

A panel connector for securely connecting an edge connector of a temperature gradient sensing probe having a support shaft to a monitoring circuit is disclosed. The panel connector includes a base having a top side containing a support shaft receiving channel therein. A plurality of resilient electrical contacts formed from a first conductive material and at least one resilient electrical contact formed from a second conductive material, which is dissimilar from the first conductive material, reside on the top side of the base. The connector is provided with a cover for clamping the edge connector and the support shaft of the temperature sensing probe in the connector.
