A patient profile is selected
Touch ENV to enable this function
A diverging dotted green line show 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 repeatedly, if needed, to toggle between lines angled from upper left to
lower right and lines angled from upper right to lower left
The system does not support the biopsy guide functionDo not use nor assemble any kind of
needle guide kits/brackets on the transducer supported to avoid transducer damage or hurting
the patient
Color/CPA Mode Image Controls
Overview
Color mode is used to detect the presence, direction, and relative velocity of blood flow by assigning color-
coded information to these parameters The color is depicted in a region of interest (ROI) that is overlaid on
the 2D image Non-inverted flow towards the transducer is assigned shades of red, and flow away from the
transducer displays in shades of blue
All forms of ultrasound-based imaging of red blood cells are derived from the received echo of the
transmitted signal The primary characteristics of this echo signal are its frequency and its amplitude (or
power) The frequency shift is determined by the movement of the red blood cells relative to the transducer
flow towards the transducer produces a higher-frequency signal and flow away from the transducer
produces a lower-frequency signal Amplitude depends on the amount of moving blood within the volume
sampled by the ultrasound beam Large frequency shift generated by rapid flow is displayed in lighter
colors, and smaller frequency shift in darker colors
