Opto-acoustic thrombolysis. United States: N. p., Fiber delivered laser pulses emulsify thrombus by mechanical stresses that include a combination of pressure, The opto-acoustic system 30 receives optical power through fiber optic cable 36 from optical power source 38. Similarly, opto-acoustic sensing and transmission system 40 is connected to tank 12. The intrinsic high frequency and wide bandwidth associated both to the opto-acoustic source and to the interferometric acousto-optic element could open a way towards a “virtual biopsy”. “Virtual biopsy” is perspective to provide the physicians the possibility of studying the nature and health condition of small portions of living tissue “in situ” by using ultrasounds.

The time-resolving opto-acoustic fibre sensor for registration of acousto-optical signal parameters in devices with fibre-optic delivery systems of pulsed laser radiation and feedback system was investigated.

The intrinsic high frequency and wide bandwidth associated both to the opto-acoustic source and to the acousto-optic receiving element could open a way towards a “virtual biopsy” of biological tissue. 2016-04-17 · Opto-Acoustic Imaging • Optical energy from a laser is absorbed. 2,3,4 • Light excitation causes thermalelastic expansion within a mass which then emits a pressure (acoustic) wave that is detected by an array of acoustic sensors within a hand-held breast probe.

Jan 1, 2002 Fiber delivered laser pulses emulsify thrombus by mechanical stresses that include a combination of pressure, tension and shear stress. Laser May 11, 2014 optoacoustic imaging. In medical applications, one of the major limitations of optical sensing technology is its susceptibility to environmental. The optical cable is used with audio gear to transfer an audio signal from one device to another at the speed of light.

The acoustic waves created An opto-electronic oscillator based on guided acoustic wave Brillouin scattering in a photonic crystal fiber (PCF) stimulated by a light wave in 1 μm band is proposed and demonstrated. A short length of a homemade PCF stimulated by relatively low pump power leads to strong coupling between the pump and probe waves.
