    1. State of the Industry report on Optical Coherence Tomography

      State of the Industry report on Optical Coherence Tomography

      The first commercial optical coherence tomography (OCT) imagers were introduced to ophthalmology by Advanced Ophthalmic Devices (now owned by Zeiss Meditec) in 1992. Since then, the market for OCT systems has grown at an impressive compounded annual rate of about 45%. This segment of the biophotonics marketplace has flourished because OCT enables sub-surface imaging of translucent or opaque materials, such as human tissue, in real time at micron resolution and without the use of ionizing radiation. As a result, last year’s global sales of all OCT systems exceeded $400 million and the market now supports more than 36 OCT ...

    3. In vivo ultrahigh-resolution optical coherence tomography.

      Ultrahigh-resolution optical coherence tomography (OCT) by use of state of the art broad-bandwidth femtosecond laser technology is demonstrated and applied to in vivo subcellular imaging. Imaging is performed with a Kerr-lens mode-locked Ti:sapphire laser with double-chirped mirrors that emits sub-two-cycle pulses with bandwidths of up to 350 nm, centered at 800 nm. Longitudinal resolutions of ~1mum and transverse resolution of 3mum, with a 110-dB dynamic range, are achieved in biological tissue. To overcome depth-of-field limitations we perform zone focusing and image fusion to construct a tomogram with high transverse resolution throughout the image depth. To our knowledge this is ...

    4. Fiber optic needle probes for optical coherence tomography imaging

      Fiber optic needle probes for optical coherence tomography imaging

      A fiber optic needle probe for measuring or imaging the internal structure of a specimen includes a needle defining a bore, an optical fiber substantially positioned within the bore, and a beam director in optical communication with the optical fiber. At least a portion of the wall of the needle is capable of transmitting light. The beam director directs light from the optical fiber to an internal structure being imaged and receives light from the structure through a transparent portion of the wall. An actuating device causes motion of any, or all of, the needle, optical fiber, and beam director ...

    5. Fiber optic imaging endoscope interferometer with at least one faraday rotator

      Fiber optic imaging endoscope interferometer with at least one faraday rotator
      An imaging system for performing optical coherence tomography includes an optical radiation source; a reference optical reflector; a first optical path leading to the reference optical reflector; and a second optical path coupled to an endoscopic unit. The endoscopic unit preferably includes an elongated housing defining a bore; a rotatable single mode optical fiber having a proximal end and a distal end positioned within and extending the length of the bore of the elongated housing; and an optical system coupled to the distal end of the rotatable single mode optical fiber, positioned to transmit the optical radiation from the single ...

    6. Methods and apparatus for forward-directed optical scanning instruments

      Methods and apparatus for forward-directed optical scanning instruments
      An imaging system for performing forward scanning imaging for application to therapeutic and diagnostic devises used in medical procedures. The imaging system includes forward directed optical coherence tomography (OCT), and non-retroreflected forward scanning OCT. Also interferometric imaging and ranging techniques and fluorescent, Raman, two-photon, and diffuse wave imaging can be used. The forward scanning mechanisms include a cam attached to a motor, pneumatic devices, a pivoting device, piezoelectric transducers, electrostatic driven slides for substantially transverse scanning; counter-rotating prisms, and offset lenses are used for arbitrary scanning. The imaging system of the invention is applied to hand held probes including probes ...

    8. Surgical diagnostics, guidance, and intervention using optical coherence tomography (Thesis)

      Surgical diagnostics, guidance, and intervention using optical coherence tomography (Thesis)
      Advances in biomedical imaging technology are rapidly becoming integrated into the surgical suite for image-guidance of interventional procedures. Clinical imaging modalities including computed tomography, magnetic resonance imagine, and ultrasound offer resolutions sufficient to guide placement of surgical instruments, but insufficient to resolve tissue and cellular microstructure. Optical coherence tomography (OCT) is a new high-resolution biomedical imaging modality based on the detection of backscattered near-infrared laser light from tissue. The compact fiber-optical based OCT technology is capable of micron-scale resolution real-time imaging in non-transparent highly-scattering tissue.
