FIBROSCAN 502 TOUCH USER MANUAL [STEVE]
As soon as the probe makes contact with the skin, i.e. when a pressure change is detected,
the ultrasound transducer makes ultrasound acquisitions.
The system displays two ultrasound images used to locate a zone that satisfies the
measurement criteria:
m One in Time-Motion (TM) mode, two-dimensional grayscale image.
m The other in A mode (ultrasound signal amplitude).
The gain on the display of both modes can be adjusted using the cursor under the ultrasound
images.
These two modes serve to ensure that the probe is correctly positioned to perform a
measurement on a sufficiently thick portion of liver, visible throughout the explored depth.
They also allow the operator to ensure that the measurement will not be disrupted by the
presence of structures not of interest, such as blood vessels.
Liver targeting tool
A B
Liver targeting tool: A: Liver indicator history. B: Real-time liver indicator.
The user can use the liver targeting tool to position the probe at an appropriate point for
measuring the liver stiffness and/or CAP.
As soon as the probe is in contact with the patient's skin, the liver targeting tool characterizes
the quality of the ultrasound signals propagating in the liver using a color scale.
Color scale: Black: The quality of the ultrasound signals is low. Green: The quality of the
ultrasound signals is high.
The greener the liver indicator, the higher the quality of the ultrasound signals, and the better
the position of the measurement point.
四 Liver targeting tool is available with the M* and XL* probes only.
