Saving Prospective and Retrospective Loops
In 2D, Color, and Power Doppler modes, the Terason system can acquire loops either
prospectively or retrospectively. Prospective acquisition captures a loop of live scan
following the acquire command, while retrospective acquisition saves a loop of a frozen
scan.
Saving Prospective Loops
During live imaging, clicking the Save Loop button tells the system to acquire and save a
loop of the scan following the button click. The loop displays in the Thumbnail window at
the left of the Main Screen. The default length of the loop is 3 seconds, but this is
adjustable between 1 and 10 seconds on the Acquisition tab of the Options menu (
Tools >
Options > Acquisition
).
