1-24

2D-mode Controls



■

2D-mode size

Narrowing the sector angle may increase the frame rate. This action will increase the TI. Pulse

voltage may be automatically adjusted down with software controls to keep the TI below the system

maximums. A decrease in pulse voltage will decrease MI.

■

Zoom

Increasing the zoom magnication may increase frame rate. This action will increase the TI. The number

of focal zones may also increase automatically to improve resolution. This action may change MI since

the peak intensity can occur at a dierent depth.

■

Persistence

A lower persistence will decrease the TI. Pulse voltage may be automatically increased. An increase in

pulse voltage will increase MI.

■

Focal no.

More focal zones may change both the TI and MI by changing frame rate or focal depth automatically.

Lower frame rates decrease the TI. MI displayed will correspond to the zone with the largest peak

intensity.

■

Focus

Changing the focal depth will change the MI. Generally, higher MI values will occur when the focal

depth is near the natural focus of the transducer.

Color and Power Controls



■

Color Sensitivity

Increasing the color sensitivity may increase the TI. More time is spent scanning for color images. Color

pulses are the dominant pulse type in this mode.

■

Color Sector Width

Narrower color sector width will increase color frame rate and the TI will increase. The system may

automatically decrease pulse voltage to stay below the system maximum. A decrease in pulse voltage

will decrease the MI. If pulsed Doppler is also enabled then pulsed Doppler will remain the dominant

mode and the TI change will be small.
