Abstract: Systems and methods for correcting an electrocardiogram (ECG) impacted by the magnetohydrodynamic (MHD) effect are provided. The systems and methods derive patient information from images captured by a camera, and use this information to calculate a T-wave correction factor used to counteract the amplification of the T-wave due to the MHD effect. While the patient undergoes an MRI scan, an ECG monitor captures an ECG signal for the patient, and the camera captures a series of images of the patient. The series of images are provided to the image processing unit (IPU). The IPU processes the images to derive patient information to calculate the T-wave correction factor. The IPU then attenuates the amplitude of the T-wave of the captured ECG signal to generate a corrected ECG signal. This corrected ECG signal is then used by the MRI scanner for more accurate gated imaging.

Abstract: An operator node is configured to generate a visualization of the configurations of nodes communicatively coupled to the operator node via a network. The operator node scans target nodes in a network and identifies a set of attributes describing various configuration properties of each node. The operator node compares corresponding attributes across nodes and determines for each attribute a measure of variance. The variance for each attribute is displayed in a grid view, allowing a user to observe the level of similarity or dissimilarity of each attribute across the target nodes of the network. The operator node also defines and implements a policy describing a set of configuration properties with which target nodes must comply. The operator node determines if one or more target nodes is in violation of the policy, displays a differential visualization associated with each policy failure event, and enables an operator to re-configure target nodes accordingly.

Abstract: A device receives during an RF receive cycle a magnetic resonance signal (250) from an area of interest of a patient (20) which is generated in response to a RF transmit signal (350) of an MRI system (100) during an RF transmit cycle. The device includes: an RF receive coil (301); a detector (330); and a first coupling (840) device adapted to couple to an input of the detector (330) a signal (350) which is proportional to a current flowing through the RF receive coil (301) during the RF transmit cycle. The detector (330) outputs a signal (350), which indicates the magnitude and/or phase of the current flowing through the RF receive coil (301) during the RF transmit cycle. The digital signal (350) may be used to stop MR scanning, and/or to notify a system (100) operator, before harm can occur to the patient (20) due to excessive current in the RF receive coil (301) during the RF transmit cycle.
