    1. Perimeter Medical Imaging Closes Oversubscribed $C4.4M Financing

      Perimeter Medical Imaging Closes Oversubscribed $C4.4M Financing

      Perimeter Medical Imaging, Inc., the leader in real-time tissue imaging in the operating suite is pleased to announce the completion of a pre-public financing round raising $C4.4million. Perimeter intends to go public via a reverse takeover (RTO) with New World Resources (NW) in Q4 of this year. Funds raised in this pre-public round and anticipated RTO will support the commercialization of Perimeter's U.S. Food and Drug Administration (FDA) cleared OTISTM medical imaging technology. OTISTM is deployed in the surgical suite, empowering surgeons with real-time tissue imaging to help optimize cancer surgery outcomes. "We are pleased to have ...

    2. Culprit lesion morphology in young patients with st-segment elevated myocardial infarction: A clinical, angiographic and optical coherence tomography study

      Culprit lesion morphology in young patients with st-segment elevated myocardial infarction: A clinical, angiographic and optical coherence tomography study

      Background and aims About 20% of patients with ST-segment elevated myocardial infarction (STEMI) are young adults. Morphological characteristics of culprit lesion in young STEMI patients have not been systematically evaluated in vivo . The present study aimed to investigate culprit lesion characteristics in young patients versus older patients using optical coherence tomography (OCT). Methods 1442 STEMI patients who underwent OCT examination of culprit lesion were included and divided into young group (age ≤50 years, n = 400) and older group (age >50 years, n = 1042). Clinical characteristics, angiography and OCT findings were compared between the two groups. Results Culprit lesions in STEMI ...

    3. Optical coherence refraction tomography

      Optical coherence refraction tomography

      Optical coherence tomography (OCT) is a cross-sectional, micrometre-scale imaging modality with widespread clinical application. Typical OCT systems sacrifice lateral resolution to achieve long depths of focus for bulk tissue imaging, and therefore tend to have better axial than lateral resolution. Such anisotropic resolution can obscure fine ultrastructural features. Furthermore, conventional OCT suffers from refraction-induced image distortions. Here, we introduce optical coherence refraction tomography (OCRT), which extends the superior axial resolution to the lateral dimension, synthesizing undistorted cross-sectional image reconstructions from multiple conventional images acquired with angular diversity. In correcting refraction-induced distortions to register the OCT images, OCRT also achieves spatially ...

    5. Intranasal micro-optical coherence tomography imaging for cystic fibrosis studies

      Intranasal micro-optical coherence tomography imaging for cystic fibrosis studies

      Cystic fibrosis (CF) is a genetic disease caused by mutations in the CF transmembrane conductance regulator (CFTR) gene. Although impairment of mucociliary clearance contributes to severe morbidity and mortality in people with CF, a clear understanding of the pathophysiology is lacking. This is, in part, due to the absence of clinical imaging techniques capable of capturing CFTR-dependent functional metrics at the cellular level. Here, we report the clinical translation of a 1-μm resolution micro-optical coherence tomography (μOCT) technology to quantitatively characterize the functional microanatomy of human upper airways. Using a minimally invasive intranasal imaging approach, we performed a clinical ...

    6. High-spatial-resolution deep tissue imaging with spectral-domain optical coherence microscopy in the 1700-nm spectral band

      High-spatial-resolution deep tissue imaging with spectral-domain optical coherence microscopy in the 1700-nm spectral band

      We present three-dimensional (3-D) high-resolution spectral-domain optical coherence microscopy (SD-OCM) by using a supercontinuum (SC) fiber laser source with 300-nm spectral bandwidth (full-width at half-maximum) in the 1700-nm spectral band. By using low-coherence interferometry with SC light and a confocal detection scheme, we realized lateral and axial resolutions of 3.4 and 3.8  μm in tissue ( n   =  1.38), respectively. This is, to the best of our knowledge, the highest 3-D spatial resolution reported among those of Fourier-domain optical coherence imaging techniques in the 1700-nm spectral band. In our SD-OCM, to enhance the imaging depth, a full-range method was ...

    7. Computational adaptive optics for optical coherence tomography using multiple randomized subaperture correlations

      Computational adaptive optics for optical coherence tomography using multiple randomized subaperture correlations

      Computational adaptive optics (CAO) is emerging as a viable alternative to hardware-based adaptive optics—in particular when applied to optical coherence tomography of the retina. For this technique, algorithms are required that detect wavefront errors precisely and quickly. Here we propose an extension of the frequently used subaperture image correlation. By applying this algorithm iteratively and, more importantly, comparing each subaperture not to the central subaperture but to several randomly selected apertures, we improved aberration correction. Since these modifications only slightly increase the run time of the correction, we believe this method can become the algorithm of choice for many ...
