Professor Ryan Halter is lead author on the study.

"Electrical impedance spectroscopy (EIS) and electrical impedance tomography (EIT) may provide a practical, low-cost, real-time method for assessing whether surgical margins are cancer-free during prostatectomies. If the method proves successful in subsequent in vivo studies, this approach could improve surgical success rates in the treatment of prostate cancer," reports Medical Physics Web.

"... Ethan Murphy [Research Scientist in Professor Ryan Halter's lab] of Dartmouth and colleagues are exploring the use of EIS and EIT. ... 'The results are the strongest evidence yet that an intraoperative-capable impedance probe can be used to distinguish benign from malignant prostate tissues,' Murphy says."
