Helmut Vogel Lee Weiss Norman Chigier Development of tools for safer cryogenic surgery in the treatment of cancer. Dr. Chigier's main expertise is in the fields of combustion, atomization, sprays and laser instrumentation for particle size, velocity and temperature measurement. Dr. Chigier is collaborating with the Surgical Oncology Department at Allegheny General Hospital to develop cryogenic probes for the treatment of cancer. Probes are being designed for penetrating into tumors, using liquid nitrogen to lethally freeze cancer cells. Control systems are being designed based upon probe tip temperatures, cooling rates and heat transfer through tissue.
Cryosurgery can be safer, cheaper, less painful and more effective than scalpel surgery.
