Q1E-EP1451
The needle echo image corresponds with the needle guideline, but
the actual distance from the surface of acoustic lens to the
needle guideline is approximate 3mm shorter than the numeric
value in the upper right on US image, so the numeric value is
rough indication for biopsy.
Before performing a biopsy, display the needle echo in sterile
water, and confirm that the needle echo at each distance overlaps
with the correspondent needle guideline. Water temperature
depends on the type of the ultrasound diagnostic scanner
connected to the probe. If the type of the scanner is EUB series,
HI VISION series, or Noblus, set water temperature at room
temperature. For the other type of the scanner, set it at 40
degrees Celsius.
It is fixed to 10mm
