M Assigns a lesser amount of gray scale pixel values to weak reflections in the image than Map 
C. Useful when imaging abdomen and liver. 
N S-shaped map. This map highlights tissue differentiation for a certain band of signals. Useful 
when imaging structures where you want more contrast, e.g., renal, tendon, vein, carotid, 
thyroid, breast, Cardiology, etc.

Colorize
DescriptionColorize is the colorization of a conventional B-Mode image or 
Doppler Spectrum to enhance the users ability to discern B, M, 
and Doppler Mode intensity valuations. Colorize is NOT a 
Doppler Mode. 
NOTE:  You can colorize realtime or CINE images or Timeline CINE, but 
not VCR images. 
Colorizes the gray scale image to enhance the eyes 
discrimination capability.

Rejection
DescriptionSelects a level below which echoes will not be amplified (an 
echo must have a certain minimum amplitude before it will be 
processed).
AdjustingAdjust to the right to increase and left to decrease.

LOGIQView
DescriptionLOGIQView provides the ability to construct and view a static 2D 
image which is wider than the field of view of a given transducer. 
This feature allows viewing and measurements of anatomy that 
is larger than what would fit in a single image. Examples include 
scanning of vascular structures and connective tissues in the 
arms and legs. 
LOGIQView constructs the extended image from individual 
image...

Optimizing M-Mode
Intended Use
M-Mode is intended to provide a display format and 
measurement capability that represents tissue displacement 
(motion) occurring over time along a single vector. 
Introduction
M-Mode is used to determine patterns of motion for objects 
within the ultrasound beam. The most common use is for 
viewing motion patterns of the heart. 
Typical exam protocol
A typical examination using M-Mode might...
