1. A method for controlling a medical imaging system, said method comprising:
- requesting at predetermined time intervals a response from at least one component within a plurality of subsystems of the medical imaging system;
determining that an error has occurred in the at least one component based upon a failure of the at least one component to respond to the request, wherein said requesting occurs prior to said determining;
identifying at least one subsystem of the plurality of subsystems that includes the at least one component having the determined error;
classifying the determined error as having a severity level selected from a plurality of predetermined severity levels, wherein a response is associated with each severity level of the plurality of predetermined severity levels such that the response for a first severity level of the plurality of predetermined severity levels is different than the response for a second severity level of the plurality of predetermined severity levels;
storing information relating to the determined error, wherein the information includes information usable for the at least one component having the determined error to be restored to a stable state; and
restoring automatically, using the response associated with the severity level of the classified determined error, the at least one component having the determined error to the stable state, wherein the stable state includes at least one of a system idle, an application setup, and an exam-started state, and wherein said requesting and said determining are performed by a subsystem controller.

Abstract
A system and method for fault detection and recovery in a medical imaging system are provided. The method includes monitoring operations of a plurality of subsystems of the medical imaging system and determining if an error has occurred in a subsystem based on the monitoring. The method further includes identifying at least one component within the subsystem having the determined error and automatically restoring the at least one component in the identified subsystem having the determined error.

18. A method for controlling a medical imaging system, said method comprising:
-
identifying a plurality of components of subsystems of the medical imaging system; requesting at predetermined time intervals a response from each component of the plurality of components; determining that one or more components of the plurality of components failing to respond within a predetermined time period indicates an error associated with the one or more components failing to respond, wherein said requesting occurs prior to said determining; classifying the determined error as having a severity level selected from a plurality of predetermined severity levels, wherein a response is associated with each severity level of the plurality of predetermined severity levels such that the response for a first severity level of the plurality of predetermined severity levels is different than the response for a second severity level of the plurality of predetermined severity levels; storing information relating to the determined error, wherein the information includes information usable for the one or more components failing to respond to be restored to a stable state; performing a reset of the one or more components failing to respond; and restoring to the stable state the one or more components failing to respond based on the severity level of the error, wherein the stable state includes at least one of a system idle, an application setup, and an exam-started state, and wherein said requesting and said determining are performed by a subsystem controller. - View Dependent Claims (19, 20, 21)

22. A medical imaging system comprising:
-
a plurality of subsystems each having at least one component; a subsystem controller for each subsystem of said plurality of subsystems, said subsystem controller communicating with said at least one component, said subsystem controller configured to; request at predetermined time intervals a response from said at least one component; determine, after the request occurs, that an error has occurred in said at least one component based upon a failure of said at least one component to respond to the request; classify the determined error as having a severity level selected from a plurality of predetermined severity levels, wherein a response is associated with each severity level of the plurality of predetermined severity levels such that the response for a first severity level of the plurality of predetermined severity levels is different than the response for a second severity level of the plurality of predetermined severity levels; perform a reset of said at least one component; and restore automatically said at least one component having the determined error; and a system manager communicating with each said subsystem controller of said plurality of subsystems and configured to communicate the failure to respond to each said subsystem controller. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)
