BACKGROUND Motion tracking based on spatial-temporal radio-frequency signals from the pixel representation of magnetic resonance (MR) imaging of a non-stationary fluid is able to provide two dimensional vector field maps. This supports the underlying fundamentals of magnetic resonance fluid motion estimation and generates a new methodology for flow(More)
Cardiovascular diseases can be diagnosed by assessing abnormal flow behavior in the heart. We introduce, for the first time, a magnetic resonance imaging-based diagnostic that produces sectional flow maps of cardiac chambers, and presents cardiac analysis based on the flow information. Using steady-state free precession magnetic resonance images of blood,(More)
Injuries are common within military populations, with high incidence rates well established in the literature. Injuries cause a substantial number of working days lost, a significant cost through compensation claims and an increased risk of attrition. In an effort to address this, a considerable amount of research has gone into identifying the most(More)
The response of the boundary layer over an airfoil with cavity to external acoustic forcing, across a sweep of frequencies, was measured. The boundary layer downstream of the cavity trailing edge was found to respond strongly and selectively at the natural airfoil tonal frequencies. This is considered to be due to enhanced feedback. However, the shear layer(More)
Patients with an atrial septal defect (ASD) have a left to right shunt with associated complications. Currently, various imaging modalities, including echocardiography and invasive cardiac catheterization, are utilized in the management of these patients. Cardiac magnetic resonance (CMR) imaging provides a novel and non-invasive approach for imaging(More)
A fish-inspired heaving and pitching foil was investigated in a water tunnel using dye visualisation, at Reynolds numbers between 870 and 3480 (based on the chord length) and Strouhal numbers between 0.06 and 1.37. The variation of the wake pattern with respect to the Strouhal number was investigated. Three different wake regimes were observed-a drag wake,(More)
