Equatorial and meridional intensity distributions
from the same trabecula either quiescent or in the diastolic phase between beats.
(A and B) Equatorial (A) and meridional (B) intensity distributions (black; stimulation frequency, 1 Hz; purple, quiescent). Temperature, 27°C. The steplike appearance of the equatorial reflections is due to the horizontal 8× binning of the detector pixels before readout as explained in Materials and methods. Total exposure time, 40 ms. a.u., arbitrary unit.
