Sigma Xi at Brown
Before his retirement as a surgeon, Terry McEnany, MD, held membership to more than 20 medical clubs and groups from 1976 to 1994. When Terry McEnany attended Brown University, he also was inducted into Sigma Xi.
Established in 1900, Sigma Xi at Brown University consists of professors, instructors, students, and graduates who strive to advance science and engineering. An individual must show significant achievement or a capacity for research in either field to earn a nomination for membership.
The goals of Sigma Xi at Brown include: providing national research for students; helping students to network and connect with scientists; and expanding the opportunities for research grants. Sigma Xi serves as a support group where participants help guide and encourage each other through their intensive work, as well as provide and share resources to help advance human knowledge.
Nominated faculty or alumni can earn full membership, while associate members are usually junior and senior undergraduates. Graduate students either can be nominated as associate or full members. Each university department may nominate prospective members in February, with an induction ceremony following in May.
Blood Flow Monitoring
Based in the Boston area, Terry McEnany, MD, completed advanced training at Massachusetts General Hospital. Terry McEnany, MD, is experienced in diverse aspects of cardiovascular and thoracic surgery, and stays informed of latest developments in his field.
In early 2016, University of Waterloo, Canada researchers announced the creation of a portable, noninvasive device designed to provide real-time monitoring of blood flow throughout the entire body. The touchless device employs a coded hemodynamic imaging approach to measuring blood flow at several arterial points.
Traditional blood-flow measurement approaches rely on blood-pulse readings at single points in the body. Whole-body imaging, coupled with continuous data collection, offers a much better picture of what is occurring throughout the body. The new photoplethysmographic imaging (PPGI) approach does not involve skin contact, as sensors use ambient and active light fluctuations as a way of measuring changes in local blood volume. The PPGI system has several potential uses, and may be particularly suited to monitoring neonatal intensive care infants and patients with severe burns and extremely contagious diseases.
