Abstract

A sequence power on controller (SPoC) is disclosed that helps organize power on sequence for subsystems of a magnetic resonance (MR) system and minimizes peak power requirement during MR system power on stage. Meanwhile, the SPoC includes additional features to help enhance reliability of the MR system. SPoC connects to a main breaker of the MR system directly and receive power from the main breaker. SPoC connects to various sensors and receive feedback signals from them. SPoC also connects to subsystems and send out sequence control signals to power on them. Control signals sent out from SPoC to subsytems are direct enable signals to control the subsystem.

SEQUENCE POWER ON CONTROLLER FOR SUBSYSTEMS IN MAGNETIC RESONANCE IMAGING (MRI)

BACKGROUND

The present invention relates generally to a magnetic resonance imaging (MRI) system and more particularly to a sequence power on controller for subsystems in the MRI system.

Generally, in a conventional Magnet Resonance (MR) system, power on sequence for subsystems is not well organized. As a result, a high peak power is required during power up stage of the MR system.

Therefore, it would be desirable to have a device that organizes power on sequence for subsystems of the MR system and minimizes peak power requirement during power on stage.

DETAILED DESCRIPTION

A sequence power on controller (SPoC) is disclosed that helps organize power on sequence for subsystems of a magnetic resonance (MR) system and minimizes peak power requirement during MR system power on stage. Meanwhile, the SPoC includes additional features to help enhance reliability of the MR system.

Fig. 1 depicts a comparison between non-sequence power on and sequence power on.

Figure 1

The above Figure obviates that required peak power when system power is on can be minimized with organized subsystems power on sequence.

Figure 2 depicts a diagrammatic view of SPoC hardware function.

Figure 2

As illustrated in Figure 2, SPoC connects to a main breaker of the MR system directly and receive power from the main breaker. SPoC connects to various sensors and receive feedback signals from them, such as grid power quality sensor signal, ambient temperature sensor signal, and ambient humidity sensor signal, among others. SPoC also connects to subsystems and send out sequence control signals to power on them.

Figure 3 depicts a diagrammatic view of SPoC software function.

Figure 3

As illustrated in the flow diagram in Figure 3, SPoC starts working when main breaker of the MR system is switched on, while other subsystems are in OFF status. Several signals fr...
