The Biomedical Optics Laboratory at UNC-Charlotte is devoted to development of novel therapeutic and diagnostic laser applications in medicine. The lab performs applied, clinically-driven research and provides a bridge between physicists/engineers and doctors. This presentation provides an overview of promising laser technologies for potential treatment or diagnosis of “Quality-of-Life” problems in urology:
(1) Thulium fiber laser vaporization of kidney stones:
The solid-state Holmium:YAG laser (=2120 nm) currently used for lithotripsy is limited by its poor spatial beam profile – the large fibers used may break, damaging endoscopes, and prevent sufficient saline irrigation, compromising visibility and safety. Fiber lasers provide high power coupling into smaller, more flexible fibers for use in latest flexible endoscopes, with improved bending and higher irrigation rates. The thulium fiber laser (=1908 nm) matches a major water absorption peak in tissue, thus providing lower ablation thresholds and more efficient stone ablation than the Holmium laser.
(2) Erbium:YAG laser incision of urethral strictures using mid-infrared optical fibers:
Endoscopic applications of mid-IR lasers have been limited due to the lack of a suitable fiber delivery system. A hybrid germanium oxide/sapphire fiber is a biocompatible, flexible, robust, high-power fiber for endoscopic delivery of Erbium:YAG laser radiation (=2940 nm). The Erbium laser may provide precise, cellular level vaporization of scar tissue in the urinary tract for treatment of incontinence.
(3) Noninvasive laser vasectomy using a Ytterbium fiber laser:
Vasectomy is the most effective, safest, and least expensive method of sterilization. However, due to male fears of incision, bleeding, infection, and pain associated with surgical vasectomy, female sterilization (tubal ligation) remains more popular. Deeply penetrating near-infrared Ytterbium fiber laser radiation (=1075 nm) in conjunction with cryogen spray cooling, can be used to perform noninvasive male sterilization which may increase the popularity of vasectomy.
(4) Optical coherence tomography (OCT) of the prostate nerves:
The cavernous nerves course along the prostate surface and are responsible for sexual function. Surgeons have difficulty identifying and sparing these nerves during prostate cancer surgery. OCT is an ideal technology for high-resolution imaging of these nerves and can easily be integrated into standard laparoscopic and robotic instruments for intra-operative diagnosis.
(5) Infrared laser stimulation of the cavernous nerves:
Optical nerve stimulation (ONS) using pulsed infrared light has recently been developed as an alternative to conventional electrical nerve stimulation. ONS provides several advantages, including non-contact stimulation, increased spatial selectivity, and elimination of stimulation artifacts. Our laboratory is investigating ONS as an intra-operative fiber optic method that complements OCT for identification of the cavernous nerves.
Nathaniel Fried is currently an Associate Professor in the Department of Physics and Optical Science and Director of the Biomedical Optics Laboratory at the University of North Carolina at Charlotte, and an Adjunct Assistant Professor in the Department of Urology at Johns Hopkins Medical School, in Baltimore, MD. Dr. Fried received his Ph.D. in Biomedical Engineering from Northwestern University in 1998 while working in the area of laser tissue welding. As a joint postdoctoral fellow at the Johns Hopkins Applied Physics Laboratory and the Department of Biomedical Engineering at Johns Hopkins Medical School, he worked on designing novel laser balloon catheters for use in treating cardiac arrhythmias. From 2000-2006, he was a faculty member in the Department of Urology at Johns Hopkins Medical School and the Director of the Biomedical Optics Laboratory at Johns Hopkins Bayview Medical Center. Dr. Fried has over 15 years of experience working in the field of laser-tissue interactions and laser medicine. He has been a member of both the American Society for Laser Medicine and Surgery (ASLMS) and the Society of Photo-Instrumentation Engineers (SPIE) since 1998, and he currently serves as an editorial board member for the journals, Lasers in Surgery and Medicine and Lasers in Medical Science. Dr. Fried has published over 100 manuscripts, conference proceedings, and book chapters in laser medicine and currently holds several patents in the field. He is the past recipient of three Young Investigator Awards for his research in laser medicine, and he has received extramural research funding from a number of federal agencies (NIH, DOD, DOE, USAID), private foundations (Whitaker, NKF), and industry. In addition to actively performing research in the field of laser medicine, Dr. Fried also currently teaches an undergraduate introductory course in Medical Physics and a graduate course in Biomedical Optics at UNC-Charlotte.

Automated Manufacturing and Medical Technology Under One Roof - the .decimal Plant Tour, 13 July, 2:00 PM
The International Test and Evaluation Association - Central Florida (ITEA-CF) Chapter, the University of Central Florida Business Incubation Program, and the Medical Training, Treatment and Technology (MT3) network are proud to announce an upcoming plant tour of .decimal(r) (pronounced"dot-decimal") in Sanford, FL on Wednesday, 13 July beginning at 2:30 PM.
.decimal(r) offers a state of the art capability converting medical scans into rapidly fabricated, precision devices designed to help save patient lives during cancer treatment. The facility has also produces other devices, including components for human surrogate manikins, in a rapid prototype to production cycle through automation and Internet based business model processes.
Visitors will learn the .decimal(r) story, and see the actual production floor where the challenges of medical patients around the globe are turned into hardware destined to help save and improve their lives.
For those interested in learning more, the attached ITEA-CF Areas of Distinction article provides the background information on .decimal(r). Feel free to share the attached article and promotional flyer with others.
We hope you will join us in Sanford, FL on Wednesday, July 13, 2011 beginning at 2:30pm.
Refreshments and hors d'ouvres will be served and time to socialize and network will be provided through 5:00pm.
An RSVP is required to attend the July 13th facility tour and social.
Please send an email to Karen Sweat at firstname.lastname@example.org or call 407-330-3300 or 800-255-1613 by July 6th to confirm attendance.

Subject: User Issues in Stereoscopic 3D Displays
Dr. Martin Banks is a vision scientist at Visual Space Perception Laboratory at UC Berkeley. He will discuss the use of stereoscopic 3D displays in industry and impact on the user. In addition, he will discuss technical criteria relevant to effect use of stereoscopic 3D displays.
In this Webinar you will learn:
A variety of user issues.
The temporal protocols used in stereo 3D and how they affect perceived flicker, motion artifacts, and depth distortions
Head roll, vertical eye movements, and visual discomfort
Visual-vestibular conflict and nausea
Vergence: the inward or outward turning movement of the eyes in convergence or divergence
Accommodation: the focusing of the eyes to make the image on the retinas sharp.
Vergence and accommodation in natural viewing; coupling
Vergence and accommodation in stereo displays
Optometric measures of discomfort
Evidence that vergence-accommodation conflict with stereo displays causes discomfort: blurry vision, tired eyes, and headache
The effect of viewing distance
The effect of the direction of the conflict (content in front of the screen or behind?)
Maintaining comfort in different viewing situations
Relating these findings to current practice
