Image Optimization 5-29
5.7.3 Left Ventricular Opacification (LVO)
Basic Procedures for LVO:
1. Acquire ECG signal ；
2. Tap [Probe] on the touch screen to open Probe/Exam Mode selecting dialogue box;
3. Select the probe and LVO exam mode; Workflow of LVO is similar to abdomen contrast
imaging.
5.7.4 Measurement, Comments and Body Marks
The system supports image measurement, comment and body mark functions. For details, see the
relevant sections.
5.7.5 Contrast Imaging QA
CAUTION:
Contrast Imaging QA images are provided for reference only, not
for confirming a diagnosis.
Contrast Imaging QA adopts time-intensity analysis to obtain perfusion quantification information of
velocity flow. This is usually performed on both suspected tissue and normal tissue to get specific
information of the suspected tissue.
1. Perform image scanning, freeze the image and select a range of images for analysis; or select
a desired cine loop from the stored images.
NOTE: in case of inaccuracy of the data, do not adjust the depth and the pan-zoom when
saving the cine.
2. Tap [Contrast QA] to activate the function.
3. Mark out the interested part (ROI).
If necessary, perform curve fitting on the time-intensity curve.
4. Analyze the parameters of the curve, or perform B measurement.
5. Save the curved image, export the data and do parameter analysis.
