Probes and Biopsy 13-15

When performing biopsy procedures, use only sterile
ultrasound gel that is certified to be safe. And manage
the ultrasound gel properly to ensure that it does not
become a source of infection.

When performing the operation concerning biopsy,
wear sterile gloves.

Image of the biopsy target and the actual position of the
biopsy needle:
Diagnostic ultrasound systems produce tomographic
plane images with information of a certain thickness in
the thickness direction of the probe. (That is to say, the
information shown in the images consist all the
information scanned in the thickness direction of the
probe.) So, even though the biopsy needle appears to
have penetrated the target object in the image, it may
not actually have done so. When the target for biopsy is
small, dispersion of the ultrasound beam may lead to
image deviate from the actual position. Pay attention to
this.
If the target object and the biopsy needle appear in the
image as shown in the figures below (For reference
only):
The biopsy needle appears to reach the target object in
