Laser speckle contrast imaging of blood flow in rat retinas using an endoscope.
Ponticorvo A, Cardenas D, Dunn AK, Ts'o D, Duong TQ. Ponticorvo A, et al. J Biomed Opt. 2013 Sep;18(9):090501. doi: 10.1117/1.JBO.18.9.090501. J Biomed Opt. 2013. PMID: 24064947 Free PMC article.
Laser speckle contrast imaging (LSCI) offers a cost-effective means to image blood flow in vivo. However, it is not commonly used to image rodent retinas because of the challenges associated with imaging through the curved cornea and delivering light through the highly sca …

How to build a Laser Speckle Contrast Imaging (LSCI) system to monitor blood flow.
Ponticorvo A, Dunn AK. Ponticorvo A, et al. J Vis Exp. 2010 Nov 11;(45):2004. doi: 10.3791/2004. J Vis Exp. 2010. PMID: 21113112 Free PMC article.
Laser Speckle Contrast Imaging (LSCI) is a simple yet powerful technique that is used for full-field imaging of blood flow. The technique analyzes fluctuations in a dynamic speckle pattern to detect the movement of particles similar to how laser Doppler analyzes fre …

Simultaneous imaging of oxygen tension and blood flow in animals using a digital micromirror device.
Ponticorvo A, Dunn AK. Ponticorvo A, et al. Opt Express. 2010 Apr 12;18(8):8160-70. doi: 10.1364/OE.18.008160. Opt Express. 2010. PMID: 20588661
In this study we present a novel imaging method that combines high resolution cerebral blood flow imaging with a highly flexible map of absolute pO(2). In vivo measurements of pO(2) in animals using phosphorescence quenching is a well established method, and …
