„ In TVM mode, adjustable parameters are the same as those in B, M, and TVI modes;
please refer to the relevant contents for details.
„ Items that appear in the menu or the soft menus are dependent upon preset, which
can be changed or set through "[Setup] → [Image Preset]"; please refer to "5.13
Image Preset" for details.
In each TDI mode, parameters that can be adjusted are similar to those in the color flow
modes (Color, PW, and Power); please refer to relevant chapters for details. The following
is to introduce the specific items in TDI mode.
Tissue State
Description This function is used for a fast image optimization by providing an
adjustment on 2 parameters, including scale and filter.
Operation Adjust through the [Tissue State] item in the soft menu or menu.
There are 3 levels provided to adjust: L, M, H.
5.9.4 TDI Quantitative Analysis (QA)
CAUTION:
TDI Quantitative Analysis results are provided for reference
only, not for confirming a diagnosis. Please compare the results
with that of other machines, or make diagnosis using
none-ultrasound methods.
TDI QA is applied for TVI original data analysis, for evaluating the velocity change of the
same cardiac muscle with cardiac cycles.
