Performing Puncture and Biopsy
Superimpose
puncture line
Press the system Puncture or Biopsy control button to superimpose a puncture line
on the image.
If more than one puncture line is available, refer to the applicable system user guide
for instructions on how to change which one appears.
Move the transducer until the puncture line transects the target. Insert the needle and
monitor it as it moves along the puncture line to the target. The needle tip echo will
be seen as a bright dot on the screen.
The puncture line will differ depending on the imaging plane orientation. In the
sagittal plane, the puncture path is indicated by a line of dots. The distance between
each puncture dot is 5mm.
In the transverse plane, a single dot indicates the point at which the needle will
transect the imaging plane.
To remove the puncture line from the image, refer to the applicable system user guide
for instructions.
WARNING P-w1
Before you start imaging, verify that the type number or name of the transducer and the type
number or description of the needle guide you are using match the number displayed on the
monitor. Also make sure that the needle guide is positioned correctly. If the numbers do not
match, or if the needle guide position is not correct, the puncture line on the monitor may
not correspond to the true puncture path in the tissue. In case of any inconsistency, stop
imaging, turn off the system, and contact your BK service representative.
WARNING P-w4
The puncture line on the image is an indication of the expected needle path. To avoid
harming the patient, the needle tip echo should be monitored at all times so any deviation
from the desired path can be corrected.
WARNING
TC-w4
If you detach the needle guide during interventional procedures, the transducer cover could
be damaged. To avoid cross-contamination, cover the transducer with a new transducer
cover before reattaching the needle guide.
WARNING
P-w5
Avoid unnecessary tissue damage. When performing a biopsy, always make sure that the
needle is fully drawn back inside the needle guide before moving the transducer.
