SAXS images. In (a), (b) and (c) identical SAXS profiles are shown, highlighting with markers diffraction peaks of filaments: (a) the fifth order of the ∼65 nm axial spacing of collagen type 1, (b) a distance attributed to the elastin fibril diameter and (c) the first order of the 38–43 nm axial spacing of myofilament. These filament SAXS signals were used in the multi modal analysis of the SAXS patterns; providing images of parameters related to abundance and SAXS orientation of collagen [(d) and (e)], elastin [(f) and (g)] and myofilament [(h) and (i)]. The peak amplitude and thus abundance is coded as brightness. The correspondence of color to orientation of the SAXS signal is indicated via the color disc.
