6 Image Acquisition
Quick Angle
Adjusts the angle faster in increments of 60°, and the real-time value of which is displayed in the
image parameter area.
The function is available in real-time imaging, freeze or cine review status.
Dynamic Range (Dyn Ra.)
The dynamic range conveys the information that being transformed from echo intensity to gray
scale.
With the contrast range, dynamic range, information displayed more, the noise increases more as
well.
Volume
Adjusts the output audio in spectrum Doppler.
Utilizing the output audio helps to identify the feature and status of flow.
Steer
Adjusts the scan angle in PW mode, so as to change the angle between the transmitting beam and
flow direction.
Obtain more information with immobility of the probe.
Values of steer angles vary with the probe.
NOTE:
Steer is available only for linear probes.
6.10 TDI
TDI mode is intended to provide information of low-velocity and high-amplitude tissue motion,
specifically for cardiac movement.
There are 4 types of TDI mode available:
• Tissue Velocity Imaging (TVI): This imaging mode is used to detect tissue movement with
direction and speed information. Generally the warm color indicates the movement towards
the transducer, while the cool color indicates the movement away from the transducer.
• Tissue Energy Imaging (TEI): This imaging mode reflects the status of cardiac movement by
providing the energy information, the larger the energy is, the brighter the color becomes.
• Tissue Velocity Doppler Mode (TVD): This imaging mode provides direction and speed
information of the tissue.
• Tissue Velocity M Mode (TVM): This function assists to observe the cardiac motion through a
direct angle.
6.10.1 TDI Mode Image Scanning
Perform the following procedure:
1. Tap <TDI> on the screen or the user-defined <TDI> key to enter the TDI mode.
– In B or B+Color mode: to enter TVI Mode, parameters of TVI mode will be displayed on
the touch screen.
– In Power mode: to enter TEI Mode, parameters of TEI mode will be displayed on the
touch screen.
