Fig. 3

The same (a) B-mode, (b) SLSC, (c) harmonic B-mode, and (d) HSCI images as in Fig. 3 with intervening skin and subcutaneous tissue layers. Neither thrombi is visible within the clutter of the fundamental B-mode image. The thrombus at 45mm, however, is visible in SLSC image where clutter has been suppressed. The harmonic B-mode also reduces clutter and shows good visualization of the thrombus at 45mm, although clutter obscures the other thrombus. The HSCI image shows good delineation of the chamber walls and both thrombi while reducing clutter. Depth-dependent gain is applied to the SLSC images to minimize depth-dependent brightness variations.
