Autor: Karel J. Zuzak, Abhas Thapa, Ganesh V. Raj, Michael S. Holzer, Jeffrey A. Cadeddu, Sara L. Best, Neil Jackson

Publikováno v: Journal of Urology. 186:400-404

DLP® hyperspectral imaging is a technology that can be used to construct a highly sensitive, noninvasive, real-time tissue hemoglobin saturation map. This almost video rate technology may be a tool to monitor renal perfusion/oxygenation during hilar

Autor: Sabira C. Naik, George Alexandrakis, Khosrow Behbehani, D. L. Hawkins, Karel J. Zuzak, Edward H. Livingston

Publikováno v: The American Journal of Surgery. 195:491-497

Background Current methodologies for imaging the biliary system during cholecystectomy are cumbersome and do not eliminate the risk of bile duct injury. We describe an approach to intraoperative biliary imaging that will enable surgeons to see throug

Characterization of a Near-Infrared Laparoscopic Hyperspectral Imaging System for Minimally Invasive Surgery

Autor: Karel J. Zuzak, Sabira C. Naik, George Alexandrakis, Doyle Hawkins, Khosrow Behbehani, Edward H. Livingston

Publikováno v: Analytical Chemistry. 79:4709-4715

We developed and characterized a new imaging platform for minimally invasive surgical venues, specifically a system to help guide laparoscopic surgeons to visualize biliary anatomy. This platform is a novel combination of a near-infrared hyperspectra

Publikováno v: Emerging Digital Micromirror Device Based Systems and Applications V.

The selection of well-vascularized tissue during DIEP flap harvest remains controversial. While several studies have elucidated cross-midline perfusion, further characterization of perfusion to the ipsilateral hemiabdomen is necessary for minimizing

Spectral light source distribution variations to enhance discrimination of the common bile duct from surroundings in reflectance hyperspectral images

Autor: Karel J. Zuzak, Edward Livingston, Mira J. Fein, Eleanor Wehner, Maritoni Litorja, Roderich E. Schwarz

Publikováno v: Emerging Digital Micromirror Device Based Systems and Applications V.

The classification of anatomical features using hyperspectral imaging has been a common goal in biomedical hyperspectral imaging. Identification and location of the common bile duct is critical in cholecystectomies, one of the most common surgical pr

Hyperspectral image segmentation of the common bile duct

Autor: Eleanor Wehner, Karel J. Zuzak, Roderich E. Schwarz, Daniel V. Samarov, Edward Livingston

Publikováno v: Emerging Digital Micromirror Device Based Systems and Applications V.

Over the course of the last several years hyperspectral imaging (HSI) has seen increased usage in biomedicine. Within the medical field in particular HSI has been recognized as having the potential to make an immediate impact by reducing the risks an

Renal oxygenation during robot-assisted laparoscopic partial nephrectomy: characterization using laparoscopic digital light processing hyperspectral imaging

Autor: Eleanor Wehner, Karel J. Zuzak, Ephrem O. Olweny, Sara L. Best, Stephen Faddegon, Jeffrey A. Cadeddu, Yung K. Tan, Neil Jackson

Publikováno v: Journal of endourology. 27(3)

Background and Purpose: Digital light processing-based hyperspectral imaging (DLP(®)-HSI) was adapted for use during laparoscopic surgery by coupling the spectral illumination source with a conventional laparoscopic light guide and incorporating a c

Calibration and Validation Scheme for In Vivo Spectroscopic Imaging of Tissue Oxygenation

Autor: Robert C. Chang, Jeffrey A. Cadeddu, Eleanor Wehner, Karel J. Zuzak, David W. Allen, Jeeseong Hwang, Edward H. Livingston, Maritoni Litorja, Sara L. Best

Publikováno v: Advances in Experimental Medicine and Biology ISBN: 9781461447719

The determination of the level of oxygenation in optically accessible tissues using multispectral or hyperspectral imaging (HSI) of oxy- and deoxyhemoglobin has special appeal in clinical work due to its noninvasiveness, ease of use, and capability o
