Cardiac Gated MR Imaging of Cerebrospinal Fluid Flow
Journal of Computer Assisted Tomography, 1985This is a preliminary investigation of the cerebrospinal fluid (CSF) spaces using cardiac gated magnetic resonance imaging. A variation of intensity of the signal from the cerebral aqueduct is demonstrated during the cardiac cycle. The pattern of this variation suggests pulsatile CSF flow.

To design magnetorheological devices and to understand how they work, one should first know the relationship between the sheer stress and sheer rate in the magnetorheological fluid [1].

MR Evaluation of Pulmonary Interstitial and Intravascular Fluids
Investigative Radiology, 1986Serial dilutions of sheep plasma and red blood cells were made yielding blood samples of various hematocrits (Hcts). These samples were studied at bore temperature (34 degrees C) in a 0.25 T pulsed NMR analyzer for differences in T1 and T2. An inverse relationship between Hct and T1 was demonstrated (P less than .001); no change was detected in T2 with

MR-fluid-based haptic interface
2006A haptic interface based on magneto-rheological (MR) fluids is presented. The device is aiming for low inertia and the possibility of emulating quasi free-space motion as well as moderate resistive forces. It is based on the direct shear operating mode of the MR fluid with a slider.

Magnetorheological (MR) fluids: Principles and applications
Smart Materials Bulletin, 2001Abstract In the relatively well established family of smart materials such as those based on ferroelectricity, piezoelectricity, magnetostriction, electrostriction and the shape memory effect, there resides another sub-set of materials known as ‘field responsive fluids’.

The Shock and Vibration Digest, 2006
This paper presents a review of the state of the art in magnetorheological technology. As magnetorheological fluids continue to gain attention, the research and development of these fluids must keep pace. Since their invention in 1948, MR fluid development has made significant advancements.

Flow characteristics of some MR-fluids
2005In this report the results of viscosity measurements of magnetorheological fluids (MRfluids) with and without magnetic field are presented. The studied magnetorheological fluids were MRF132LD, MRF336AG and 11 MC, which is a Russian MRfluid (Rus1). Also some observations on composition of the fluids are presented.
