Abstract :
Submicrosecond pulsed laser diode stroboscopic synchronous illuminator combined with microscopic CCD TV camera is devised as dedicated visualization system to monitor microbubble/microballoon contrast agent under pulsed insonification. It successfully monitored cracking and dying process of microballoon, however, due to system timing accuracy problem the submicrosecond snapshot photography on the exact instance of cracking is yet to be, but shortly, performed
