TDI Quantitative Analysis (QA)
CAUTION:
TDI Quantitative Analysis results are provided for reference
only, not for confirming diagnoses. Compare the results with
those of other machines, or make diagnoses using non-
ultrasound methods.
TDI QA is applied for TVI original data analysis, for evaluating the velocity change of the
same cardiac muscle with cardiac cycles.
TDI QA Workflow:
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.
Tip:
z
Images from the current scan session (already in freeze mode) or from a saved
image loop can be used for TDI QA.
z
TDI QA is only available if the user has selected an image loop. If the user has
selected a saved still image (just one frame), the TDI QA function is not available.
2. Tap [TDI-QA] on the TVI touch screen page to activate the TDI QA function, or press
the user-defined key for TDI QA directly.
3. Mark out the part of interest.
4. Save the curved image, export the data and perform parameter analysis.
5. Tap [Exit] to exit the TDI QA function.
