The procedure below works for the iE33 and EPIQ machines, but not the CX50 model. Other Philips models have not been tested yet, but may work.
Increase the horizontal sweep speed so that Speed is set to ”Fast”, corresponding to 100 mm/s.
Set the number of beats to be acquired to 20 or longer. Some software versions may have a maximum of 20 beats, others may allow more beats depending on hardware and software version. We suggest setting the duration of acquisition to 30 seconds and Retrospective acquisition. Record a 30 second long loop by selecting Acquire without selecting Freeze. Note, if one presses Freeze before Acquire, then only that one screen width will be saved. However, if one presses Acquire without Freeze, then the entire 30 second recording will be saved (retrospectively or prospectively depending on preferred settings). It is not immediately possible to see and verify on the Philips machine if the entire loop has been saved. This is verified later in the reviewing environment. Thus, it important to press Acquire without pressing Freeze.
