“…4. These results highlight that an efficient source of ultrasound can be obtained by coupling a fiber optic to a low-power pulsed laser, if a graphite or graphite compound layer capable of absorbing laser light is mounted at the fiber end [5], [7]. The highest efficiency can he obtained by using a layer with small thickness and high graphite concentration.…”

“…For the proposed probe completely based on a fiber optic technology, a strong miniaturization can be obtained, making it suitable for the construction of intravascular, and endoluminal and percutaneous applications [7]. Such probes might make it possible to trace a path towards "virtual biopsy"; in fact, according to recent developments, wide-band ultrasonic probes could be placed in close proximity of a tumor by a catheter or needle [7].…”

An ultrasonic probe was developed by using, in conjunction, opto-acoustic and acousto-optic devices based on fiber optic technology. 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" of the biological tissue by means of appropriate signal processing techniques to investigate frequency-selective responses in tissue. Extreme miniaturization, which can be obtained by fiber optic technology, permits the positioning of the probe in the close proximity of the focal lesion, avoiding the reduction of the penetration depth imposed by the strong attenuation at high frequency.

“…This change in thickness produces a modification in the interferometer reflectance, defined as the ratio between the reflected and incident light power, and thus induces a change in the light intensity detected by a photodiode.For the proposed probe, completely based on a fiber optic technology, a strong miniaturization can be obtained, making it suitable for intravascular, endoluminal and percutaneous applications. Such probes might make it possible to trace a path towards "virtual biopsy"; in fact, these wide band ultrasonic fiber optic probes could be placed in close proximity of a focal lesion by a catheter or a needle [6]. In 2006 the first ultrasonic images obtained with a fully fiber optic ultrasonic probe were presented [7].…”

MOMS technology for fully fiber optic ultrasonic probes: A proposal for virtual biopsy

An ultrasonic probe was developed by using, in conjunction, opto-acoustic and acousto-optic devices based on fiber optic technology. 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. A Micro-Opto-MechanicalSystem (MOMS) approach is proposed to realize the broadband ultrasonic probe on micromachined silicon frames suited to be mounted on the tip of optical fibers.
