Improved ECG based gating in ultra high field cardiac MRI using an independent component analysis approach
نویسندگان
چکیده
Background Cardiac gating in ultra high field (UHF) MRI is a challenging task due to the magnetohydrodynamic (MHD) effect [1]. The MHD effect is particularly severe at such field strengths and severely distorts the electrocardiogram (ECG). State-of-the-art ECG based gating methods which use the vectorcardiogram (VCG) [2] are thus prone to errors [1]. This work presents an approach which separates the ECG and the MHD signal using Independent Component Analysis (ICA).

Limitations of VCG based gating methods in ultra high field cardiac MRI
Background The electrocardiogram (ECG) is important for gating purposes in cardiac magnetic resonance imaging (CMR). However, the magnetohydrodynamic (MHD) effect, which is caused by the flow of blood in the static magnetic field, makes it difficult to record clean ECG signals for gating. The vectorcardiogram (VCG), which can be derived from the ECG signal, is commonly used for gating purposes ...
متن کاملNon-contact cardiac gating with ultra-wideband radar sensors for high field MRI
Cardiac MR (CMR) imaging in a defined phase of the heart cycle requires triggered data acquisition. Systems with B0 up to 1.5 T utilize ECG signals for triggering. However, due to the increasing perturbing influence of the magneto-hydrodynamic effect on the ECG signal, triggering is additional hampered in high and ultrahigh field MRI systems. The necessity to attach ECG electrodes to the human ...
متن کاملImproved cardiac motion self-gating
Background Cardiac motion self-gating is a technique where MRI signal is used to derive motion triggers instead of ECG, which might be problematic in high B0 field or cases where ECG is not accessible (e.g. fetal cardiac imaging). However, the performance of existing cardiac self-gating approaches have not yet enabled clinical utility. We propose and evaluate here a novel cardiac self-gating st...
متن کاملImproved cardiac gating at 3T with the “3D-QRS” method utilizing MRI-compatible 12-lead ECGs
Background Blood is rapidly ejected from the left ventricle during early systole, travels in the aortic arch perpendicular to the MRI’s main field, thus generating a Magnetohydrodynamic (MHD) voltage which is larger than the real ECG QRS complex in high field MRI. The MHD voltage (VMHD) is severally irregular in patients with arrhythmia, since arrhythmic ECG beats are interleaved between succes...
متن کاملECG-based gating in ultra high field cardiovascular magnetic resonance using an independent component analysis approach
BACKGROUND In Cardiovascular Magnetic Resonance (CMR), the synchronization of image acquisition with heart motion is performed in clinical practice by processing the electrocardiogram (ECG). The ECG-based synchronization is well established for MR scanners with magnetic fields up to 3 T. However, this technique is prone to errors in ultra high field environments, e.g. in 7 T MR scanners as used...
