Probes and Biopsy 13-13
Dispersion of the ultrasound beam
The biopsy needle may not have actually entered the
target object even though it appears to have done so
on the image. To avoid this problem, note points below:
Do not rely only on the needle tip on the image. Pay
careful attention to that, when the biopsy needle comes
into the target object or contacts with it, the object
should shift slightly.
Before you perform the biopsy, please evaluate the size
of the object and confirm if the biopsy can be carried
out.
