    2. Polarization sensitive optical coherence tomography (PS-OCT) for bronchoscopic airway smooth muscle detection in bronchial thermoplasty treated asthma patients

      Polarization sensitive optical coherence tomography (PS-OCT) for bronchoscopic airway smooth muscle detection in bronchial thermoplasty treated asthma patients
      To the editor, 79 Asthma is a chronic inflammatory disease characterized by airway remodeling (AR), 80 including thickening of airway smooth muscle (ASM) as a key element of this alteration (1). 81 Severe asthma patients may benefit from bronchial thermoplasty (BT), an endoscopic 82 treatment that targets structural AR and induces ASM reduction (2). Assessment of AR is 83 critical to evaluate the impact of BT and might provide a ...

    4. Pre-Emptive OCT-Guided Angioplasty of Vulnerable Intermediate Coronary Lesions: Results from the Prematurely Halted PECTUS-Trial

      Pre-Emptive OCT-Guided Angioplasty of Vulnerable Intermediate Coronary Lesions: Results from the Prematurely Halted PECTUS-Trial
      Objectives: To assess the safety and efficacy of pre-emptive treatment of optical coherence tomography- (OCT-) derived vulnerable, non-flow-limiting, non-culprit lesions in patients with myocardial infarction (MI). Background: Intracoronary imaging with OCT can aid in the decision to treat non-flow-limiting lesions by identifying vulnerable plaques. Pre-emptive treatment of these lesions might improve patient outcome by "sealing" these plaques. Bioresorbable vascular scaffolds (BVS) have theoretical benefit for this treatment because they dissolve ...

    5. Analysis of attenuation coefficient estimation in Fourier-domain OCT of semi-infinite media

      Analysis of attenuation coefficient estimation in Fourier-domain OCT of semi-infinite media
      The attenuation coefficient (AC) is an optical property of tissue that can be estimated from optical coherence tomography (OCT) data. In this paper, we aim to estimate the AC accurately by compensating for the shape of the focused beam. For this, we propose a method to estimate the axial PSF model parameters and AC by fitting a model for an OCT signal in a homogenous sample to the recorded OCT ...

    8. Subretinal Fibrosis Detection Using Polarization Sensitive Optical Coherence Tomography

      Subretinal Fibrosis Detection Using Polarization Sensitive Optical Coherence Tomography
      Purpose : Subretinal fibrosis (SRFib) is an important cause of permanent loss-of-vision diseases with submacular neovascularization, but a reliable diagnostic method is currently missing. This study uses polarization-sensitive optical coherence tomography (PS-OCT) to detect SRFib within retinal lesions by measurement of its birefringent collagen fibers. Methods : Twenty-five patients were enrolled with retinal pathology in one or both eyes containing (1) suspected SRFib, (2) lesions suspected not to be fibrotic, or (3 ...

    9. Toward clinical elastography of dermal tissues: A medical device to probe skin’s elasticity through suction, with subsurface imaging via optical coherence tomography

      Toward clinical elastography of dermal tissues: A medical device to probe skin’s elasticity through suction, with subsurface imaging via optical coherence tomography
      ABSTRACT The mechanical behavior of dermal tissues is unarguably recognized for its diagnostic ability and in the last decades received a steadily increasing interest in dermatology practices. Among the various methods to investigate the mechanics of skin in clinical environments, suction-based ones are especially noteworthy, thanks to their qualities of minimal invasiveness and relative simplicity of setups and data analysis. In such experiments, structural visualization of the sample is highly ...

      In vivo characterization of chick embryo mesoderm by optical coherence tomography assisted microindentation
      Embryos are growing organisms with highly heterogeneous properties in space and time. Understanding the mechanical properties is a crucial prerequisite for the investigation of morphogenesis. During the last ten years, new techniques have been developed to evaluate the mechanical properties of biological tissues in vivo . To address this need, we employed a new instrument that, via the combination of micro-indentation with Optical Coherence Tomography (OCT), allows us to determine both ...

    13. Computational-imaging-based optical coherence tomography in time- and frequency-domain

      Computational-imaging-based optical coherence tomography in time- and frequency-domain
      A computational 3D imaging system is developed that enables polychromatic, depth-resolved, diffraction-limited imaging of semi-transparent objects. By combining coherent diffractive imaging (CDI) and optical coherence tomography (OCT), we reconstruct tomographic images of 3D objects from a set of wavelength- and phase-resolved diffraction patterns, using numerical methods to achieve image quality beyond the hardware limits of the optical systems used. We implement both time- and frequency-domain versions of full-field OCT systems ...

    16. Optical coherence tomography velocimetry based on decorrelation estimation of phasor pair ratios (DEPPAIR)

      Optical coherence tomography velocimetry based on decorrelation estimation of phasor pair ratios (DEPPAIR)
      Quantitative velocity estimations in optical coherence tomography requires the estimation of the axial and lateral flow components. Optical coherence tomography measures the depth resolved complex field reflected from a sample. While the axial velocity component can be determined from the Doppler shift or phase shift between a pair of consecutive measurements at the same location, the estimation of the lateral component for in vivo applications is still challenging. One approach ...
