Two scripts for the analysis of platelet aggregation in microfluidic channels after whole blood perfusion. The first script, “Platelet_Coverage”, automatically corrects for channel misalignment, determines a threshold using the triangle method, creates a black and white image representing platelet coverage and finally determines the platelet coverage. The second script, “Clot_Properties”, uses the black and white image from the first script to determine the platelet aggregate size distribution.

Triange Thresholding is done using a script of dr. Panneton (MathWorks, #28047) which is based on the original work of Zack, Gregory W., William E. Rogers, and S. A. Latt. "Automatic measurement of sister chromatid exchange frequency." Journal of Histochemistry & Cytochemistry 25.7 (1977): 741-753.
