B.FPA16 probes have a longitudinal steering wave range of [+ or -]35[degrees], and MB.FPA16 probes a steering range of [+ or -]45[degrees], which provides comprehensive sector scan coverage without the need for wedges.
Their algorithm seems effective and robust for 5 basic ASTs: circular scan, sector scan, raster scan, helical scan, and conical scan.
This technique first entails cross-sectional visualisation of the radial artery in the midpoint of the sector scan. The operator should identify a straight portion of the vessel by panning the probe proximally and observing no change in the relative medio-lateral position of the vessel in the sonogram.
There's also a feature called sector scan. With user-adjustable scan angles of up to 90-degrees, scanning sectors is helpful for a focused look at storms in a given sector.
Adjusting the tilt or sector scan is as easy as a swipe of the finger across the display.
In a sector scan of a deep structure using a convex transducer, the image has a V-shape or fan shape.
