Abstract
The guest editors introduce a feature issue commemorating the 25th anniversary of optical coherence tomography.
© 2017 Optical Society of America
This feature issue commemorates the approximately 25 year history of Optical Coherence Tomography (OCT), one of the most successful biophotonic technologies. While OCT has technological origins traceable to ultrafast laser development and fiber optic system test instrumentation of the 1980’s, innovations in low coherence interferometry for optical ranging and imaging for biomedical applications in the U.S., Europe and Japan by the early 1990’s led to coinage of the now widely known term OCT in 1991 [1]. As discussed in the following cited Invited Review and Invited Research articles in this issue, remarkable strides have since been made in OCT technology encompassing novel light sources [2], imaging system architectures [3, 4], and sample/patient interface technologies including endoscopic [5], catheter-based [6], intra-operative [7], adaptive-optic [8–10], computational [11] and microscope-based [12] implementations. Functional extensions of OCT have been developed featuring polarization-based [13], Doppler [14], elastographic [15], tractographic [16], spectroscopic [17, 18] multi-modal [19] and angiographic [8, 20, 21] contrast, the latter of which has taken on particular current excitement and topically comprises the plurality of articles published in this Issue. Clinical applications of OCT have been developed in dozens of medical specialties, led by its most mature applications in ophthalmology and cardiology, where OCT has become a clinical standard of care and is now performed in an estimated 30 million OCT imaging procedures per year [22]. Over this 25 year period, thousands of researchers across the globe have published thousands of patents, as well as tens of thousands of research articles concerning OCT technology and applications [22]. The economic and clinical impact of OCT, summarized in an Invited Review article in this Issue [22], currently supports hundreds companies supplying OCT components and systems into a more than $1B yearly OCT system market, and has been estimated to have accumulated ~$10B in Medicare savings in U.S.
To review the remarkable history, current state, and preview the equally promising future of OCT, this Feature Issue comprises 50 articles authored by many of the most prominent researchers, clinicians, and entrepreneurs in the OCT community. The Issue features 12 in-depth Invited Review Articles, the largest collection of reviews yet published in this burgeoning field, from historic leaders in OCT technology and applications, and 9 Invited Research Articles on topics of intense current interest. The Issue also includes 29 contributed Research articles on active topics of current research interest.
The Guest Editors wish to extend their sincere thanks to all of the authors, and more than a hundred confidential reviewers, who contributed to this landmark issue. We are particularly indebted to the authors of all of the invited articles who agreed to take on and have completed this daunting task. The Editors are also grateful to the OSA staff who supported this effort with their habitual professionalism and good cheer. We anticipate that the contents of this Issue will stand as an authoritative source on the history and current state of this exciting field, and look forward to many future anniversaries of OCT’s contributions optics, science, and medicine.
