Figure 4 Context information of the reflux esophagitis lesion. A: Captured at 00:00:18, representing the earliest result; B: Captured at 00:00:19, representing an earlier frame at this time point; C: Captured at 00:00:19, representing a continued frame subsequent frame, showing further details of the lesion; D: Captured at 00:00:19, representing a later frame at this time point, where the lesion area might reveal new angles or further details due to the capsule’s movement.
