Anterior segment biometry using ultrasound biomicroscopy and the Artemis-2 very high frequency ultrasound scanner
PURPOSE To compare the precision of anterior chamber angle (ACA) and anterior chamber depth (ACD) measurements taken with ultrasound biomicroscopy (UBM) and the Artemis-2 Very High Frequency Ultrasound Scanner (VHFUS) in normal subjects. DESIGN Prospective study. METHODS We randomly selected one eye from each of 59 normal subjects in this study. Two subjects dropped out of the study; the as...
متن کاملLow-frequency quantitative ultrasound imaging of cell death in vivo.
PURPOSE Currently, no clinical imaging modality is used routinely to assess tumor response to cancer therapies within hours to days of the delivery of treatment. Here, the authors demonstrate the efficacy of ultrasound at a clinically relevant frequency to quantitatively detect changes in tumors in response to cancer therapies using preclinical mouse models. METHODS Conventional low-frequency...
متن کاملHigh-frequency ultrasound analysis of post-mitotic arrest cell death
Non-invasive monitoring of cancer cell death would permit rapid feedback on treatment response. One technique showing such promise is quantitative ultrasound. High-frequency ultrasound spectral radiofrequency analysis was used to study cell death in breast cancer cell samples. Quantitative ultrasound parameters, including attenuation, spectral slope, spectral 0-MHz-intercept, midband fit, and f...
متن کاملMeasurement of the crystalline lens radius with artemis very high frequency ultrasound biomicroscopy for implantable collamer lens sizing.
To the Editor: In their recent article, Reinstein et al.1 described the use of the Artemis 2 very high frequency digital ultrasound (ArcScan, Inc., Morrison, CO) to calculate the fit of the Visian Implantable Collamer Lens (ICL). Another parameter previously proposed as influencing ICL vaulting is the crystalline lens anterior radius of curvature (ALR).2 The ALR has not yet been used in any pre...
متن کاملOverview of Ultrasound Biomicroscopy
Ultrasound biomicroscopy (UBM) is a high-resolution ultrasound technique that allows noninvasive in vivo imaging of structural details of the anterior ocular segment at near light microscopic resolution and provides detailed assessment of anterior segment structures, including those obscured by normal anatomic and pathologic relations. This review gives an overview regarding the instrument, tec...
