Does anyone know of any public data sets containing human vasculature? We are currently developing tracing algorithms for vasculature. These algorithms are being developed for intra-vital MP confocal sets (mice), but we would like to see if they could be adapted to work with another imaging modality. Thanks Rich Richard Cole Research Assistant Professor

Richard,
This is a shot in the dark, but I am guessing that someone at the
University of Washington Vascular Imaging Lab could possibly get you
the information you need.
The Vascular Imaging Lab
University of Washington 815 Mercer Street Box 358050 If it is not this group then it maybe another at UW. Once upon a
time there was a group at UW that was heavily involved in computer
simulation studies of capillary structures and blood flow.
You might check them out.

Hi Rich, FARsight project, http://www.farsight-toolkit.org/wiki/Main_Page see http://www.farsight-toolkit.org/wiki/Special:FarsightDownloads types of download: data sets (Zeiss LSM files ... Badri should be able to send you more data), and first paper: Neurosci Methods. 2008 May 15;170(1):165-78. Epub 2008 Jan 17. Associative image analysis: a method for automated quantification of 3D multi-parameter images of brain tissue.Bjornsson CS, Lin G, Al-Kofahi Y, Narayanaswamy A, Smith KL, Shain W, Roysam B.Center for Neural Communication Technology, New York State Department of Health, Wadsworth Center, Albany, NY 12201-0509, USA. AbstractBrain structural complexity has confounded prior efforts to extract quantitative image-based measurements. We present a systematic 'divide and conquer' methodology for analyzing three-dimensional (3D) multi-parameter images of brain tissue to delineate and classify key structures, and compute quantitative associations among them. To demonstrate the method, thick ( approximately 100 microm) slices of rat brain tissue were labeled using three to five fluorescent signals, and imaged using spectral confocal microscopy and unmixing algorithms. Automated 3D segmentation and tracing algorithms were used to delineate cell nuclei, vasculature, and cell processes. From these segmentations, a set of 23 intrinsic and 8 associative image-based measurements was computed for each cell. These features were used to classify astrocytes, microglia, neurons, and endothelial cells. Associations among cells and between cells and vasculature were computed and represented as graphical networks to enable further analysis. The automated results were validated using a graphical interface that permits investigator inspection and corrective editing of each cell in 3D. Nuclear counting accuracy was >89%, and cell classification accuracy ranged from 81 to 92% depending on cell type. We present a software system named FARSIGHT implementing our methodology. Its output is a detailed XML file containing measurements that may be used for diverse quantitative hypothesis-driven and exploratory studies of the central nervous system.PMID: 18294697 George At 12:31 PM 8/16/2010, you wrote: Does anyone know of any public data sets containing human vasculature?
