A multi-frame DICOM object packages many images in a single file (common for cardiac XA, US sweeps, OPT, and enhanced CT/MR). The viewer plays these as a continuous stack or as video.
Step 1: Open a multi-frame series
Multi-frame series display with a film-strip icon on the thumbnail. Click the thumbnail to load it. The viewer detects the object type and chooses stack or video mode automatically.
Step 2: Play or step through frames
Press Space to play and pause. Use the scrollbar or the mouse wheel to step frame-by-frame. The frame counter at the bottom of the viewport shows the current position.
Step 3: Adjust playback speed
Right-click the viewport and open Cine. Set the frame rate in frames per second, or use the slider. Cine remembers the last setting per modality, so a faster speed you set for echo studies persists for subsequent echo reads.
Step 4: Apply windowing to all frames
Windowing changes affect the whole series, not just the current frame. Enable Sync Windowing in the toolbar if you want windowing to match across multiple multi-frame series in different viewports.
Tips
- Enhanced multi-frame objects for CT, MR, NM, MG, and OPT modalities render as a series, not as a video. Treat them the same way you would a conventional stack.
- MPEG-2 and MPEG-4 encoded objects are supported. If playback is choppy, check that hardware acceleration is enabled in your browser.
