    2. Optical coherence tomography angiography and cutaneous wound healing

      Optical coherence tomography angiography and cutaneous wound healing
      Background: Examination of the skins vascular and structural features is essential in clinical, medical, and research dermatology. However, there is a lack of comprehensive imaging tools that clearly and accurately evaluates the skins vascular and structural features. Current techniques are invasive and have inherent preparatory drawbacks. Aim: To use optical coherence tomography angiography (OCTA) for a more accurate depiction of vessels in the skin without the use of a dye ...

      Special Section Guest Editorial: Commemorating 25 Years of Optical Coherence Tomography: a Perspective on Biomedical Applications
      ptical coherence tomography (OCT) has become a major medical imaging technology in the time since its inception now more than 25 years ago. During this time, OCT has become very well established in ophthalmology, and this application area largely dominates the field. Next in importance and stage of development is cardiovascular medicine, also a strongly commercial technology, but at an earlier stage and a slower pace of uptake than ophthalmology ...

    7. Methods and systems for integrated imaging using optical coherence tomography and photoacoustic imaging

      Methods and systems for integrated imaging using optical coherence tomography and photoacoustic imaging
      Systems and methods for photoacoustic imaging are provided. Photoacoustic signals are excited from a body and the excited photoacoustic signals are detected with a low coherence interferometer system serving as a photoacoustic detector. Cross-sectional images of the body are then reconstructed by the system from the detected photoacoustic signals.

    8. Long ranging swept-source optical coherence tomography-based angiography outperforms its spectral-domain counterpart in imaging human skin microcirculations

      Long ranging swept-source optical coherence tomography-based angiography outperforms its spectral-domain counterpart in imaging human skin microcirculations
      There is an increasing demand for imaging tools in clinical dermatology that can perform in vivo wide-field morphological and functional examination from surface to deep tissue regions at various skin sites of the human body. The conventional spectral-domain optical coherence tomography-based angiography (SD-OCTA) system is difficult to meet these requirements due to its fundamental limitations of the sensitivity roll-off, imaging range as well as imaging speed. To mitigate these issues ...

    9. Multifunctional in vivo imaging for monitoring wound healing using swept-source polarization-sensitive optical coherence tomography

      Multifunctional in vivo imaging for monitoring wound healing using swept-source polarization-sensitive optical coherence tomography
      Background and Objective Wound healing involves a complex and dynamic biological process in response to tissue injury. Monitoring of the cascade of cellular events is useful for wound management and treatment. The aim of this study is to demonstrate the potential of multifunctional polarization-sensitive optical coherence tomography (PS-OCT) to longitudinally monitor the self-healing process in a murine cutaneous wound model. Materials and Methods A multi-functional PS-OCT system based on swept ...

    10. Complex signal-based optical coherence tomography angiography enables in vivo visualization of choriocapillaris in human choroid

      Complex signal-based optical coherence tomography angiography enables in vivo visualization of choriocapillaris in human choroid
      The choriocapillaris (CC) plays an essential role in maintaining the normal functions of the human eye. There is increasing interest in the community to develop an imaging technique for visualizing the CC, yet this remains underexplored due to technical limitations. We propose an approach for the visualization of the CC in humans via a complex signal-based optical microangiography (OMAG) algorithm, based on commercially available spectral domain optical coherence tomography (SD-OCT ...

    11. A benchmark study of automated intra-retinal cyst segmentation algorithms using optical coherence tomography B-scan

      A benchmark study of automated intra-retinal cyst segmentation algorithms using optical coherence tomography B-scan
      Retinal cysts are formed by accumulation of fluid in the retina caused by leakages from inflammation or vitreous fractures. Analysis of the retinal cystic spaces holds significance in detection and treatment of several ocular diseases like age-related macular degeneration, diabetic macular edema etc. Thus, segmentation of intra-retinal cysts and quantification of cystic spaces are vital for retinal pathology and severity detection. In the recent years, automated segmentation of intra-retinal cysts ...

    12. Optical coherence tomography angiography as an imaging modality for evaluation of diabetic macular edema

      Optical coherence tomography angiography as an imaging modality for evaluation of diabetic macular edema
      iabetic retinopathy remains a leading cause of blindness worldwide in patients aged 2064 years. [1] Diabetic macular edema (DME) threating or involving the fovea is a common etiology for vision loss. Traditionally, treatment methods have been guided by contact and non-contact slit lamp biomicroscopy, fluorescein angiography and fundus stereo photography. [1] Fluorescein angiography (FA) is a dynamic, invasive imaging technique first described in 1961 and more thoroughly invested and popularized ...

    13. Utility of optical coherence tomography angiography in detecting glaucomatous damage in a uveitic patient with disc congestion: A case report

      Utility of optical coherence tomography angiography in detecting glaucomatous damage in a uveitic patient with disc congestion: A case report
      Purpose To report a case of uveitic glaucoma with congested optic disc where optical coherence tomography angiography (OCT-A) provided diagnostic utility in assessing glaucomatous damage but optical coherence tomography (OCT) alone had limited utility. Observations We report a case of a 33-year-old Caucasian female referred to the USC Roski Eye Institute for uncontrolled intraocular pressure (IOP) in the left eye. She was managed by an outside provider for 6 months ...

    14. Flexible wide-field optical micro-angiography based on Fourier-domain multiplexed dual-beam swept source optical coherence tomography

      Flexible wide-field optical micro-angiography based on Fourier-domain multiplexed dual-beam swept source optical coherence tomography
      Wide-field optical coherence tomography angiography (OCTA) is gaining interest in clinical imaging applications. In this pursuit, it is challenging to maintain the imaging resolution and sensitivity throughout the wide field of view (FoV). Here, we propose a novel method/system of dual-beam arrangement and Fourier domain multiplexing to achieve wide field OCTA when imaging the uneven surface samples. The proposed system provides two separate FoVs, with flexibility that the imaging ...
