The axial resolutions for USI and PAI are 32.6 ± 1.9 μm and 40.4 ± 1.6 μm, respectively, and the lateral resolutions are 110.4 ± 21.8 μm and 148.4 ± 13.5 μm, respectively (Fig. 4b). The measured axial and lateral resolutions show a strong correlation ...
We demonstrate this new ultrasound sensor on an optical-resolution photoacoustic microscope. The axial and lateral resolutions are 48 μm and 3.3 μm. The field of view is up to 1.57 mm2. The sensor exhibits strong resistance to environmental perturbations, such as temperature changes,...
UBM is an excellent tool for anterior segment imaging and in the diagnosis of various ocular pathologies. Despite the advent of newer imaging modalities like AS-OCT, UBM still has a role in the management of certain disorders due to its axial and lateral resolutionand depth of penetration. ...
and a novel multi-depth expression method to overcome those issues in developed high speed image system. B-mode image of the chicken phantom by 25MHz transducer shows the resolution of lateral and axial resolutions are up to 123μm and 59μm respectively. In addition, the experiment ...
(Axial and Lateral)Probe: coupled to the phantom with gel, positioned in retort stand over an area of the phantom with wire targets.Image acquisition and measurement (repeat for both probe views): Freeze image. Measure axial/lateral dimension of the target. Record this dimension(Slice thickness...
Whereas image quality is mostly judged on its axial and lateral resolution (both components are in plane), an important but often overlooked characteristic of ultrasound is the elevational resolution which corresponds with the width of the imaging plane, also known as slice thickness or elevational ...
Single-element transducer based ultrasound (US) imaging offers a compact and affordable solution for high-frequency preclinical and clinical imaging because of its low cost, low complexity, and high spatial resolution compared to array-based US imaging. To achieve B-mode imaging, conventional approache...
For example, gain in the axial or the lateral imaging dimension can be controlled in a region by using slide potentiometers for each depth in the image. The Regional Expansion® feature and the zoom feature found in commercial imaging systems also provide a very limited amount of regional ...
