5.9.3 TDI Image Optimization
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 "5.16
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.
Workflow of TDI QA:
1. Perform image scanning on cardiac muscle, freeze the image and select a range of
images for analysis; or select a desired cine loop from the stored images.
Tips:
Images from the current scan session (already in freeze mode) or from a saved
image loop can be used for TDI QA.
TDI QA is only available for cine files. If the user has selected a single-frame
image, TDI QA function cannot be activated.
2. Click [TDI QA] on the TVI soft menu to activate TDI QA function.
3. Mark out the interesting part.
4. Save the curved image, export the data and do parameter analysis.
5. Exit TDI QA function.
Press <Freeze> on the control panel.
