# RegionOfInterestChannels
|
||
|
|
|
||
|
|
### Purpose
|
||
|
|
This module defines a Prism event for publishing and subscribing to region of interest (ROI) channel selection changes. It enables loosely-coupled communication between components when users select channels associated with a specific region of interest, carrying both channel identifiers and names along with context about the consumer.
