1. A method for controlling transmission of medical images, the method comprising: monitoring over time estimates of bandwidth of a channel communicatively coupling an imaging location with another location remote from the imaging location; communicating the estimates to a system at the imaging location; identifying at least one of a region-of-interest (ROI) mask or one or more transmission parameters for the channel; and adjusting at least one of the ROI mask or the one or more transmission parameters based on the monitored estimates of the bandwidth for communicating the medical images.
