Probes and Biopsy 13-29
13.2.4 Verifying the Biopsy Guide Line
Adjusting the needle mark is necessary before every biopsy procedure.
1. Confirm that the needle-guided bracket has been installed securely in the correct
position.
2. Prepare a container filled with sterile water.
3. Place the head of the probe in the sterile water, and get a biopsy needle into the
needle guide.
4. When the biopsy needle appears on the image, confirm that the biopsy needle is
displayed at almost the same position as the selected needle mark.
WARNING:
1. Prior to each biopsy procedure, be sure to verify the
guide line.
2. If the needle is not consistent with the guide line, DO
NOT perform the biopsy procedure.
NOTE: You can perform guide line verification on a single live B/C image, and all
biopsy-irrelevant operations are forbidden.
