'Using XTD-View'
The quality and usefulness of XTD-View images is affected by the transducer's motion.
Incorrect technique can contribute to image distortion.
Guidance and precautions for uniform motion:
•
Make sure that there is enough coupling gel along the scan path.
•
Always move the transducer slowly and steadily. Best results are achieved by moving
the transducer with 2cm/s (max. 4cm/s).
•
Continuous contact is required throughout the length of the extended image. DO NOT lift
the transducer from the skin surface.
•
Always keep the transducer perpendicular to the skin surface. DO NOT rock, rotate or tilt
the transducer during the scan.
•
Keep the motion within the same scan plane, if possible. DO NOT slide the transducer
laterally.
•
DO NOT change the direction of movement during the scan. e.g.; DO NOT move back-
and forward while scanning.
•
The system accommodates a reasonable range of motion velocity. DO NOT make
abrupt changes in speed of motion.
•
Deeper scans generally require reduced acquisition speed.
If you are unsure whether you made a mistake during the XTD-scan, relax and repeat the
scan.
1. Perform a detailed examination of the anatomy/pathology and optimize parameters for
tissue texture and visible window PRIOR TO activating XTD-View.
2. Press the [XTD] key on the control panel. A blue box is displayed around the border of the
2D image.
3. Select the desired acquisition display. Two types of acquisition displays are available:
a. centered: The live image will always remain in the center as you build the
extended image in a 'pivot' movement left or right, mainly used for curved
transducers.
b. moving: The live image will move left or right as you build the extended
image in a ´sliding`movement, mainly used for linear transducers.
