Experimental arrangement for the X-ray intravital microscopy technique using synchrotron radiation.
Schematic of the rotating-disk X-ray shutter consisting of two disks rotating synchronously with video camera signals.
Digital zoomed images of the central area of the 10-μm-thick chart in the fields of view of (a) 4.5, (b) 7.0, and (c) 9.5 mm. Numerical values show bar widths.

Sequential images of the right coronary arteries (RCA) presenting one heart cycle. The interval is 33.3 ms in consecutive images. Large black arrows indicate the heart wall direction of motion.
Two sets of the right coronary artery (RCA) images showing effects of drug manipulation in normal (NC, NA, and NS) and hypertensive (HC, HA, and HS) rat hearts: (NC and HC) control, (NA and HA) acetylcholine stress, and (NS and HS) sodium nitroprusside stress.
Three regions of interest are shown in each image. Blood vessels were grouped into three classes of arterial diameter sizes. A symbol ϕ signifies the blood vessel diameter.
Three sets of regions of interest in the normal rat heart. The NC column is a set of controls. The NA is a set with acetylcholine stress. The NS is a set with sodium nitroprusside stress.
Three sets of regions of interest in the hypertensive rat heart.
