Probes and Biopsy 13-17
Dispersion of the ultrasound beam
The biopsy needle may not have actually entered the target
object even though it appears to have done so in the image.
To avoid this, note the points below:

Do not rely only on the needle tip in the image. Pay careful
attention to the fact that when the biopsy needle enters the
target object or comes into contact with it, the object should
shift slightly.
Before performing the biopsy, evaluate the size of the object
and confirm whether the biopsy can be carried out.
