Real-Time Adaptive Motion Correction for Coronary MR Angiography
Introduction: Artifacts due to residual coronary motion remain an impediment to diagnostic coronary MRA in a small but substantial amount of patients. Wang et al. [1] have shown that for the general population a linear relationship between the diaphragmatic and cardiac motion can be assumed. The study also shows that the principal motion of the heart can be compensated for by using the so calle...
متن کاملAdvanced Respiratory Motion Compensation for Coronary MR Angiography
Despite technical advances, respiratory motion remains a major impediment in a substantial amount of patients undergoing coronary magnetic resonance angiography (CMRA). Traditionally, respiratory motion compensation has been performed with a one-dimensional respiratory navigator positioned on the right hemi-diaphragm, using a motion model to estimate and correct for the bulk respiratory motion ...
متن کاملCoronary MR angiography using image‐based respiratory motion compensation with inline correction and fixed gating efficiency
PURPOSE The purpose of this study was to evaluate a new inline motion compensation approach called image-based navigation with Constant Respiratory efficiency UsIng Single End-expiratory threshold (iNAV-CRUISE) for coronary MR angiography (CMRA). METHODS The CRUISE gating technique was combined with iNAV motion correction and implemented inline for motion-compensated CMRA on a 1.5 Tesla scann...
متن کاملNovel prospective respiratory motion correction approach for free-breathing coronary MR angiography using a patient-adapted affine motion model.
A novel technique is presented which enables the calibration of a 3D affine respiratory motion model to the individual motion pattern of the patient. The concept of multiple navigators and precursory navigators is introduced to address nonlinear properties and hysteresis effects of the model parameters with respect to the conventional diaphragmatic navigator. The optimal combination and weighti...
متن کاملRespiratory motion correction in prostate cancer positron emission tomography: A study on patients and phantom simulation
Introduction: To investigate the effects of breathing cycle and tree diaphragm motions on prostate cancer tumors standard uptake value (SUV) during positron emission tomography (PET) and to correct it. Materials and methods: Respiratory motion traces were simulated on the common patient breathing cycle and tree diaphragm motio...
