N13C5 User Guide (16-01270-EN-06) Neurosurgical Imaging with N13C5 9
Apply sterile gel to the tip of the transducer or fill the cover with 1 to 2 ml of sterile
water. This improves screen imaging by preventing image artifacts caused by air
bubbles.
Pull the transducer cover over the transducer. Check for air bubbles between the
cover and the transducer and even out if necessary before proceeding.
For Intraoperative Applications:
• Irrigate the organ to be imaged with 0.9% sterile physiological saline solution
while imaging.
For Surface Use:
• Gel also creates a good acoustic contact between the skin and the transducer:
Therefor, apply a small amount to the outside of the cover prior to imaging and
reapply frequently.
Follow these precautions when putting sterile covers on a transducer:
• Wear sterile gloves.
• When using a puncture attachment, place it gently over the cover and secure it,
following the instructions for the puncture attachment.
• Verify that the cover has not been damaged in the process. If it has, repeat the
procedure with a new transducer cover.

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 Exam-w5
Be careful not to lose any parts of the needle guide inside the patient.
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-w6
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. You must take extra care when taking a freeangle
biopsy because the expected needle path is not shown.

N13C5 User Guide (16-01270-EN-06) Performing Puncture and Biopsy 15
If the transducer cover is damaged when attaching the puncture attachment, replace
it with a new cover.
