Robust quantitative assessment of collagen fibers with picrosirius red stain and linearly polarized light as demonstrated on atherosclerotic plaque samples
Fig 5
Total number of collagen positive pixels in cap region for different threshold for pixel counting.
Values shown are relative to no threshold (intensity value = 0). (A) Composite image from Δϴ = 2° and ϴR,full and (B) Composite image from Δϴ = 60° and ϴR,full.
