FIG. 1.

(Color online) Subwavelength wire phantom imaged using pulses (a) and chirps (b). The dynamic range is 55 dB. The scalebar represents 1 mm. (c) Comparative performance of conventional IVUS versus chirp IVUS.

FIG. 2.

(Color online) Channel phantom image using pulses (a) and chirps (b). The dynamic range is 55 dB. Human coronary artery image using pulses (c) and chirps (d). The dynamic range is 48 dB. The scalebar corresponds to1 mm.

Image of FIG. 3.
FIG. 3.

(Color online) Simulated incident down (a) and up sweep (b) chirps sent a micron size UCA bubble and corresponding scattered acoustic pressures (c) and (d). (e) Down sweep chirp image and (f) contrast image of the channel phantom perfused with the UCA. The dynamic range is 54 dB for the left image and 21 dB for the contrast image.
