The function OTI TM allows the examiner to "fine tune" the system for scanning different kinds of
tissue.
Use the [OTI] control to adjust the respective parameter. Four positions are possible:
adipose, solid, cystic or normal tissue.
Remark: Setting the relevant parameter can improve image quality.

The "Line Density" setting allows the user to make a trade-off between image resolution and
frame rate.
high: higher resolution / lower frame rate norm: normal resolution / medium
frame rate low: lower resolution / higher frame rate
The gray map determines the displayed brightness of an echo in relationship to its amplitude.
The Tint Map determines the displayed Color of an echo in relationship to its amplitude.
Depending on individual requirements a "harder" or "softer" image can be obtained with this
function and can be adjusted in freeze - and in scan mode (post-processing). The displayed
gray scale wedge corresponds to the adjusted gray map curve. Different gray map curves can
be associated with different imaging modes.
