Real-time QRS detection using integrated variance for ECG gated cardiac MRI

Autor: Schmidt Marcus, Krug Johannes W., Rose Georg

Publikováno v: Current Directions in Biomedical Engineering, Vol 2, Iss 1, Pp 255-258 (2016)

During magnetic resonance imaging (MRI), a patient’s vital signs are required for different purposes. In cardiac MRI (CMR), an electrocardiogram (ECG) of the patient is required for triggering the image acquisition process. However, a reliable QRS

Reducing of gradient induced artifacts on the ECG signal during MRI examinations using Wilcoxon filter

Autor: Schmidt Marcus, Krug Johannes W., Rose Georg

Publikováno v: Current Directions in Biomedical Engineering, Vol 2, Iss 1, Pp 175-178 (2016)

The electrocardiogramm (ECG) is the state-of-the-art signal for gating in cardiovascular magnetic resonance imaging and patient monitoring. Using the ECG for gating and monitoring during the magnetic resonance imaging examination is a high challengin

Assessing MRI susceptibility artefact through an indicator of image distortion

Autor: Illanes Alfredo, Krug Johannes W., Friebe Michael

Publikováno v: Current Directions in Biomedical Engineering, Vol 2, Iss 1, Pp 427-431 (2016)

Susceptibility artefacts in magnetic resonance imaging (MRI) caused by medical devices can result in a severe degradation of the MR image quality. The quantification of susceptibility artefacts is regulated by the ASTM standard which defines a manual

Contactless respiratory monitoring system for magnetic resonance imaging applications using a laser range sensor

Autor: Krug Johannes W., Odenbach Robert, Boese Axel, Friebe Michael

Publikováno v: Current Directions in Biomedical Engineering, Vol 2, Iss 1, Pp 719-722 (2016)

During a magnetic resonance imaging (MRI) exam, a respiratory signal can be required for different purposes, e.g. for patient monitoring, motion compensation or for research studies such as in functional MRI. In addition, respiratory information can
