PatentDOI
OCT using spectrally resolved bandwidth
Marc D. Feldman,Thomas E. Milner,Junghwan Oh,Eunha Kim,Karthik Kumar,Chris Condit,Robert Grant,Nate Kemp,Jeehyun Kim,Shaochen Chen,Li-Hsin Han +10 more
TL;DR: In this article, a multichannel optical coherence tomography system for turbid materials utilizing multiple channels of information comprising spatial, angle, spectral and polarization domains is presented. But the system is not suitable for imaging a vessel, biliary, GU and/or Gl tract of a patient.
Patent
Forward-imaging optical coherence tomography (OCT) systems and probes
TL;DR: In this article, a scanning reflector surface is configured to be rotated about two axes in a single operating plane to direct light transmitted along the sample path to a sample to be imaged.
Journal ArticleDOI
Handheld histology-equivalent sectioning laser-scanning confocal optical microscope for interventional imaging.
Karthik Kumar,Rony Avritscher,Youmin Wang,Nancy Lane,David C. Madoff,Tse Kuan Yu,Jonathan W. Uhr,Xiaojing Zhang +7 more
TL;DR: The results indicate that inexpensive, portable handheld optical microscopy tools based on silicon micromirror technologies could be important in interventional imaging, complementing existing coarse-resolution techniques to improve the efficacy of disease diagnosis, image-guided excisional microsurgery, and monitored photodynamic therapy.
Journal ArticleDOI
Fast 3D in vivo swept-source optical coherence tomography using a two-axis MEMS scanning micromirror
Karthik Kumar,Jonathan C. Condit,Austin McElroy,Nate J. Kemp,Kazunori Hoshino,Thomas E. Milner,Xiaojing Zhang +6 more
TL;DR: In this article, a fiber-based forward-imaging swept-source optical coherence tomography system using a high-reflectivity two-axis microelectromechanical scanning mirror for high-speed 3D in vivo visualization of cellular-scale architecture of biological specimens is presented.
