Method and apparatus for communicating button actuation signals for a CT scanner

摘要

The present invention is, in one embodiment, a method for efficiently and reliably communicating button presses electronically on a network from one or more push button nodes each having at least one push button, to a master node. This method includes steps of: generating status messages indicative of a push button states at each of push button node; communicating the status messages to the master node via the network; determining, at the master node, the state of the push buttons at each of the push button nodes from the communicated status messages; and triggering a response of the master node, in accordance with the statuses of the push buttons determined from the communicated status messages.
