1. A diagnostic imaging system comprising:
- a first controller that detects any unsafe or dangerous conditions in a diagnostic scanner and generates safety/emergency data indicative of the unsafe or dangerous conditions;
a communication unit that generates a safety/emergency signal from the safety/emergency data using a digital protocol and communicates the safety/emergency over a local digital network;
wherein the communication unit that generates the safety/emergency signal preempts normal packet delivery over the local digital network and inserts the safety/emergency signal onto the local digital network.

Abstract
A diagnostic imaging system includes a first controller that detects any unsafe or dangerous conditions in a diagnostic scanner and generates safety/emergency data indicative of the unsafe or dangerous conditions. A communication unit generates a safety/emergency signal from the safety/emergency data using a digital protocol and communicates the safety/emergency over a local digital network.

9. A method of communicating safety/emergency data in a diagnostic imaging system, the method comprising:
-
with at least one controller, detecting unsafe or dangerous conditions in the diagnostic imaging system; with the at least one controller, generating safety/emergency data indicative of the unsafe or dangerous conditions; with a communication unit, generating a safe/emergency signal from the safety/emergency data using a digital protocol; and with the communication unit, transmitting the safety/emergency signal over a local digital network, wherein the transmission of the safety/emerge signal preempts normal packet delivery over the local digital network. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A diagnostic imaging system comprising:
-
at least one gradient coil configured to create magnetic field gradients in an imaging bore defined by a main magnet; a cooling unit configured to cool the at least one gradient field coil; an RF transmitter coil configured to transmit RF pulses into the imaging bore; an RF receiver coil configured to receive the induced RF pulses; at least one processor programmed to detect at least one of;
overheating of the at least one magnetic field coil;
a malfunction of the cooling unit; and
the RF transmitter and the RF receiver being in an ON or connected state simultaneously;wherein the at least one processor includes at least one communication unit configured to generate a respective signal from the corresponding detection of the overheating of the at least one magnetic field coil, the malfunction of the cooling unit, and the RF transmitter and the RF receiver being in an ON or connected state simultaneously, the at least one communication unit being configured to communicate the respective signal over a local digital network to preempt normal packet delivery over the local digital network and inserting the respective signal onto the local digital network. - View Dependent Claims (17, 18, 19, 20)
