Using Image Controls
T3300 Diagnostic Ultrasound System | 81 | B00601-010 4/10/17
7.1.14 Adjusting the Sector Width and Position
Adjust the ROI of the imaging area for image width and image position. A smaller sector width
increases the frame rate.
Touch Sector Width +/- to adjust the width. Touch Sector Pos +/- to adjust the position.
7.1.15 Adjusting Power
Adjust the acoustic output power value to the expected target.
Touch Power +/- to adjust the value.
7.1.16 Using Trapezoidal Imaging
Increase the range of view of the ultrasound image when using a linear transducer.
Touch Trap to enable trapezoidal imaging.
7.1.17 Adjusting Density
Adjust the density of the scan lines. Higher density obtains better horizontal resolution with lower
frame rate, while lower density obtains higher frame rate.
Touch Density repeatedly to select a desired line density.
7.1.18 Using Compound Imaging
Reduce speckles and improve contrast resolution.
• Frequency compounding: Combine multiple images acquired from different frequencies. Touch
FQBeam to enable frequency compounding.
• Spatial compounding: Combine multiple images acquired from different beam angles. Touch
SQBeam repeatedly to enable and adjust spatial compounding.
7.1.19 Using ENV (Enhanced Needle Visualization)
When performing a biopsy with the supported transducer, the system offers on-screen needle
assistance to further enhance imaging of the needle. Before using the ENV function, make sure the
following conditions are met:
• B-mode is selected
• An L154BH transducer is connected to the system
• A patient profile is selected
Touch ENV to enable this function.
A diverging dotted green line shows in the Imaging window. The point of the needle should be close
to vertical to the dotted line. The part of the needle image that goes beyond the limit will not be
brightened and can’t be seen. Tap ENV Angle +/-, if needed, to toggle between lines angled from
upper left to lower right and lines angled from upper right to lower left.
