Doppler, M-mode, and Color Imaging Controls

When a new imaging mode is selected, both the TI and the MI will change to default settings. Each

mode has a corresponding pulse repetition frequency and maximum intensity point. In combined or

simultaneous modes, the TI is the sum of the contribution from the modes enabled and MI is the MI for

the focal zone and mode with the largest derated intensity. If a mode is turned o and then reselected,

the system will return to the previously selected settings.

■

Probe

Each probe model available has unique specifications for contact area, beam shape, and center

frequency. Defaults are initialized when you select a probe. Samsung Medison factory defaults vary with

probe, application, and selected mode. Defaults have been chosen below the FDA limits for intended

use.

■

Depth

An increase in 2D-mode depth will automatically decrease the 2D-mode frame rate. This would

decrease the TI. The system may also automatically choose a deeper 2D-mode focal depth. A change of

focal depth may change the MI. The MI displayed is that of the zone with the largest peak intensity.

■

Application

Acoustic output defaults are set when you select an application. Samsung Medison factory defaults vary

with probe, application, and mode. Defaults have been chosen below the FDA limits for intended use.
