There are two types of transducers depending on the method used to steer the ultrasound beam-mechanical and electronic. Detail resolution of tile image has two components-axial resolution and lateral resolution. Axial resolution depends upon the pulse length of ultrasound beam which is governed by ...
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,...

lateral resolution, axial resolution, and the pixel size of the image.8The lateral resolution depends on the distribution of ultrasound in the field of the transducer, which has a width at half maximum given by the product of the wavelength and the f-number...
The lateral and axial resolution, slice thickness, and caliper accuracy (vertical and horizontal) as a function of varying overall receiver gain and dynamic range, were obtained using conventional (no zoom) as well as a magnified (zoom) field of view (FOV). Each measurement was performed three...
Although studies have shown that the improvement in lateral resolution associated with MVBF is significant, the axial resolution remains unaffected. In this work, we combine MVBF and spiking deconvolution to improve both lateral and axial resolutions in synthetic aperture ultrasound imaging. We ...

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 ...
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...
