8. Velocity measurements will be represented in cm/s.
9. The difference in time between the left and right ends of the caliper will be represented as time (t) in seconds.
10. To save a Pulsed Doppler image, freeze then press the capture button.
NOTE
• The use of Doppler ultrasound during the first trimester is currently being promoted as an
aid for screening and diagnosis of some congenital abnormalities. The procedure requires
considerable skill and subjects the fetus to extended periods of relatively high ultrasound
exposure levels. Due to the increased acoustic output of spectral Doppler ultrasound, its use
in the first trimester should be viewed with caution. Spectral Doppler imaging should only be
used when there is a clear benefit/risk advantage, and both the TI and examination duration are
kept low. Protocols that typically involve TI values lower than 1.0 reflect minimal risk.
6.7. Using iQ Slice
NOTE
iQ Slice and iQ Fan availability may vary depending on probe generation, Butterfly membership
status and geographic location.
iQ Slice is a capture mode that performs single volumetric sweep acquiring multiple slices of the region of interest.
When using iQ Slice mode, you can:
• Adjust the Gain and Depth
• Take a single volumetric sweep to generate multiple slices
• Perform linear and elliptical measurements on a slice(s)
• Select a slice to save as a still image
• Save all slices as multiple still images
• Save all slices as a cine clip
Accessing iQ Slice Mode
1. Select your desired preset and identify the area you’d like to image. Note that imaging will be on B-Mode.
2. Select Actions at the bottom of the imaging screen.
3. Under Modes, select iQ Slice.
6.8. Using iQ Fan Mode
NOTE
iQ Slice and iQ Fan availability may vary depending on probe generation, Butterfly membership
status and geographic location.
