Design of a Magnetic Resonance Imaging Compatible Metallic Pressure Vessel

Abstract

Highpressure measurements in most scientific fields rely on metal vessels, a consequence of the superior tensile strength of metals. Magnetic resonance imaging in conjunction with metallic pressure vessels has recently been introduced. Magnetic resonance imaging with compatible metallic pressure vessels is a very general concept. This paper outlines the specifics of the development and design of these vessels. Metallic pressure vessels not only provide inherently high tensile strengths and efficient temperature control, they also permit optimization of the radiofrequency probe sensitivity. The design and application of magnetic resonance imaging compatible pressure vessels is illustrated through a rock core holder fabricated using nonmagnetic stainless steel. Water flooding through a porous rock at elevated pressure and temperature is shown as an example of its applications. Highpressure magnetic resonance plays an indispensable role in several scientific fields; this work will open new avenues of investigation for highpressure material science magnetic resonance imaging.
