■ Sector Position/Width/Angle
Sector width (for linear probes) or sector angle (for curved and phased array probes) is used to adjust the frame
rate. You can adjust the sector width or angle to get more information without moving the probe.
The region of interest of the object can be adjusted after you adjust the sector width or sector angle.
