Sector Scanning

A sector scan is a 2D display in polar coordinates of a series of A-Scans. In a sector scan, each A-scan (signal) corresponds to 1 steering angle. Sector-scanning consists of selecting an aperture (number of elements, smaller than the total number of elements of the probe), applying delay-laws to this aperture for steering the beam at each angle of the desired angular sector.
