Abstract: Line-by-line scanning with linear arrays is a standard image formation method in clinical ultrasound. This method examines progressively a given region of interest by conducting focused ...

Abstract: Ultrafast imaging modes, such as coherent plane-wave compounding (CPWC), increase image uniformity and reduce grating lobe artifacts by dynamic receive apertures. The focal length and the ...

The term "aperture" denotes the set of array elements that contribute to the focusing. The dynamic aperture varies with the focus and, for any given focus, seeks to achieve two properties: Centering ...

The nicest iPhone you can buy, with a stainless steel frame, OLED display, and a matte finish on the back. Ships with the new, blazing fast A13 Bionic chip. Triple-lens rear camera captures ultrawide ...

Here we've used the ratio of the sensor diagonals (more commonly referred to as the crop factor), to work out the equivalent aperture. If it helps you relate this back to the difference in sensor area ...

When floor flatness and levelness are measured using F-number technology, timing of measurements is critical because curling of slabs on ground increase with time. The result is decreased F-numbers ...

The 'F' rating is short for the 'Fujita' rating of tornados. Dr. Theodore Fujita was an atmospheric scientist at the University of Chicago who did pioneering work into the study of tornados.
