FIG. 3.

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.

FIG. 4.

Isolated perfused rat heart. The aorta was secured to the cannula with sutures. Reproduced by permission from Umetani et al., J. Inst. Image Inf. Telev. Eng. 58, 344 (2004). Copyright 2004 by The Institute of Image Information and Television Engineers.

Image of FIG. 5.
FIG. 5.

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.

Image of FIG. 6.
FIG. 6.

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.

Image of FIG. 7.
FIG. 7.

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.

Image of FIG. 8.
FIG. 8.

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.

Image of FIG. 9.
FIG. 9.

Three sets of regions of interest in the hypertensive rat heart.
