“…Development of scanning catheters has enabled endoscopic OCT imaging of internal organs and extended the OCT study field further [9,10]. Endoscopic OCT imaging has demonstrated its ability to resolve layered tissue structures, and to differentiate normal from certain pathologic conditions within the esophagus [11][12][13][14][15][16], coronary artery [17][18][19] and other internal organs such as the oral cavity [20], larynx [21][22][23], and bladder [24].…”

A two-axis scanning catheter was developed for 3D endoscopic imaging with spectral domain optical coherence tomography (SD-OCT). The catheter incorporates a micro-mirror scanner implemented with microelectromechanical systems (MEMS) technology: the micro-mirror is mounted on a two-axis gimbal comprised of folded flexure hinges and is actuated by magnetic field. The scanner can run either statically in both axes or at the resonant frequency (>= 350Hz) for the fast axis. The assembled catheter has an outer diameter of 2.8 mm and a rigid part of 12 mm in length. Its scanning range is ± 20˚ in optical angle in both axes with low voltages (1~3V), resulting in a scannable length of approximately 1 mm at the surface in both axes, even with the small catheter size. The catheter was incorporated with a multi-functional SD-OCT system for 3D endoscopic imaging. Both intensity and polarization-sensitive images could be acquired simultaneously at 18.5K axial scans/s. In vivo 3D images of human fingertips and oral cavity tissue are presented as a demonstration. Fujimoto, "Scanning single-mode fiber optic catheter-endoscope for optical coherence tomography," Opt.

“…The feasibility of OCT guidance and monitoring of laser surgery was first explored in the late 1990's [53,72], and subsequent studies demonstrated the ability of OCT to monitor structural alterations following prostate tissue ablation in vitro [147] and laser treatment of laryngeal carcinoma surgery [148]. More recently, Palanker et al in 2010 demonstrated a spectraldomain OCT system incorporated into a femtosecond laser module for human cataract surgery [73] (Fig.…”

During microsurgery, en face imaging of the surgical field through the operating microscope limits the surgeon's depth perception and visualization of instruments and subsurface anatomy. Surgical procedures outside microsurgery, such as breast tumor resections, may also benefit from visualization of the sub-surface tissue structures. The widespread clinical adoption of optical coherence tomography (OCT) in ophthalmology and its growing prominence in other fields, such as cancer imaging, has motivated the development of intraoperative OCT for real-time tomographic visualization of surgical interventions. This article reviews key technological developments in intraoperative OCT and their applications in human surgery. We focus on handheld OCT probes, microscope-integrated OCT systems, and OCT-guided laser treatment platforms designed for intraoperative use. Moreover, we discuss intraoperative OCT adjuncts and processing techniques currently under development to optimize the surgical feedback derivable from OCT data. Lastly, we survey salient clinical studies of intraoperative OCT for human surgery.

“…The biotissue is heated by the laser radiation and moved apart by the silica core of the optical¯ber. 10 The silica core is su±ciently transparent in the near IR region and is mechanically strong enough to stand the high temperatures arising at the tip of the optical¯ber tip during biotissue resection. The strongly absorbing layer at the tip of the¯ber (according to the work of Amzayyb 11 the absorption of the layer can achieve 50%) results in heating of the silica core to temperatures higher than carbonization temperature and facilitates carbon formation during biotissue dissociation resulting from the joint action of radiation and the high temperatures near the heated silica¯ber.…”

In this paper, we consider a method of laser resection using the silica glass core from which the cladding layer has been removed as the cutting part of a laser scalpel. An absorbing layer coating the silica¯ber tip markedly alters its biotissue cutting characteristics. The results of histological studies of skin after exposure to a laser scalpel with and without a strongly absorbing coating (SAC) at a wavelength of 0.97 m show that resection using a coated scalpel is more sparing. When an uncoated scalpel was used, skin injury was more apparent in both its surface spread and the depth of structural damage, resulting in poorer tissue regeneration.
