Reviewing and Interpreting RAPID Videos
Using RAPID to View a Video 141
Passage Times
Passage time is the time the capsule spent in a given region of the GI tract. Calculation of passage
times is enabled only after you segment the video from the GI tract by labeling the first images of the
different sections of the GI tract. When you identify and label the first and last images of the gastric,
SB, or cecal section of the GI tract, the RAPID software calculates the relevant passage times based on
the time tags of the landmarked thumbnails.
The RAPID software displays this data at the bottom of the Localization Display section.
Comparing Thumbnails
There are three scenarios to compare images in RAPID v8.3:
• Atlas comparison: Compare a RAPID video thumbnail to Atlas images (see Comparing Video
Images to Atlas Images on page 154).
• One thumbnail comparison: Compare a thumbnail to itself in different display modes (i.e. FICE
or Blue mode).
• Two thumbnail comparison: Compare two different thumbnails in the same video.
To compare a thumbnail to itself (One frame comparison):
1. Click the thumbnail you wish to examine.
A dark blue background appears around the thumbnail.
2. Right-click the thumbnail and select Compare Thumbnails.
A separate window appears, showing the same thumbnail duplicated, side by side.

Note
The estimation of the passage times is based solely on the physician’s
identification of the first image of each section of the GI tract.
