Mindray Z60T - Exit Free Xros M; Tdi; Basic Procedures for TDI Imaging

Image Optimization 5-23
Adjustment of the M-mark Line
Description
To adjust the position and angle of the M-mark line.
Operations
 Position Adjustment
When the M-mark line is activated, move the trackball left and right to adjust
the position. The direction is recognized by the arrow at the end of the line.
 Angle Adjustment
When the M-mark line is activated, move the trackball to adjust the fulcrum of
the line, and adjust through the [Angle] item on the menu.
5.10.2 Exit Free Xros M
In Free Xros M mode, click [Free Xros M] or press <B> or the user-defined Free Xros M key
to exit Free Xros M mode.
5.11 TDI
CAUTION:
TDI is provided for reference only, not for confirming a diagnosis.
TDI (Tissue Doppler imaging) 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 probe, while the cool color indicates the movement away from
the probe.
 Tissue Energy Imaging (TEI): This imaging mode reflects the status of cardiac
movement by displaying the intensity of tissue, the brighter the color the less the
intensity.
 Tissue Velocity Doppler Imaging(TVD): This imaging mode provides direction and
velocity information of the tissue quantificationally.
 Tissue Velocity M Imaging (TVM): This function assists to observe the cardiac motion
through a direct angle. TVM mode is also called Color Tissue M mode which has
been introduced in Color M mode chapter, please refer to “5.9 Color M Mode” for
details.
 Only phased probe can be applied for TDI function.
