Angio Imaging

7-116 Revision D.0

Adaptive Angio

Adaptive Angio provides the best angio sensitivity at every depth, while keeping

the PRF (Pulse Rate Frequency) scale constant. The following illustration shows

Adaptive Angio side-by-side images with the color box set to different depths:

View 1 - Angio box at shallow depth

View 2 - Angio box at deeper depth

Following are some Adaptive Angio guidelines:

• As the angio box moves to the top of the sector (shallow depth), the system

uses a higher angio frequency (View 1).

• When the angio box moves to the bottom of the sector, the system uses a

lower angio frequency (View 2).

• The user may override the selected frequency by

– moving the Focus control to a new depth in the angio box

– disabling Adaptive Angio Frequency
