tissue scatters, image speckle characteristics such as brightness, density or size have no apparent
value in determining tissue structure or related properties. The elimination of or significant reduction in
speckle improves the quality or diagnostic potential of the image.
The method applied in the subject modification utilizes a nonlinear diffusion filtering technique that
permits effective speckle reduction in real time. The speckle reduction filter is available to the user in all
B-mode imaging, independent of the transducer used.
5-2-4-6 SonoNT
SonoNT is an additional function for manual NT (Nuchal Translucency) measurement. This function
supports the user to find the correct position for the NT measurement. The user can switch between NT
Method "Manual" and "Sono NT" (semi-automatic).
A Box has to be placed for the NT-ROI. Then the NT-distance is calculated automatically, a graphic
(yellow head-image) and the NT-result are displayed.
If no result is found a temporary warning "No valid NT-distance found!" is displayed.
