Jerzy Rozenblit demonstrates his Computer-Aided Surgical Trainer.

With $1.9 million from the National Science Foundation, University of Arizona Distinguished Professor and Raymond J. Oglethorpe Endowed Chair Jerzy Rozenblit is developing and testing a training device that reduces surgical errors by giving surgeons a better grasp of noninvasive surgical techniques.

The Computer-Aided Surgical Trainer system will be the first to provide haptic guidance and augmented reality images for trainees when directly manipulating surgical instruments.

Under the leadership of co-principal investigator Allan Hamilton, who holds an ECE joint appointment, the CAST system will also make its way into classrooms in the UA College of Medicine - Tucson for a pilot clinical training study.

The VHIS approach can lead to sophisticated, low-cost medical instruments for identifying cancerous tissue at an early age.

His co-investigator on the project is professor Jennifer Barton of the UA department of biomedical engineering and BIO5 Institute.

The technology is now available for licensing through Tech Launch Arizona.

A handheld wireless device in development by two University of Arizona engineering professors could answer the question of how we create more wireless connections when so few remain in the spectrum.

Envision a world without lost signals or time-consuming searches for Wi-Fi connections. UA electrical and computer engineering professors Marwan Krunz (right, top) and Hao Xin (right, bottom) are working to shift how we structure wireless systems and eliminate wireless scarcity.

The surge in Wi-Fi enabled devices has been a boon for society but a strain on the wireless spectrum that provides the frequencies they use. Many of the frequencies are fixed, having been allocated exclusively for radio, television, military, mobile and other operators. What remains is limited.
