ABSTRACT:
An apparatus and a method for magnetic resonance imaging of a sample to be inspected without the sample chamber to be taken out of the apparatus under omission of renewed operation of tuning and shimming on each test, by excluding transmission of any vibration of the static and the gradient magnetic field generating elements to the detection unit, which includes supporting, within a hollow core space (4) in static and gradient magnetic field generating elements (1) and (2), a detection unit (10) composed of a sample chamber (11) and an RF-emission-reception set (12) including an RF coil (13) by a support member (14), such that they are isolated from said static magnetic field generating element (1) and from said gradient magnetic field generating element (2); performing the sample exchange by guiding the sample (15) into said sample chamber (11) via a sample transfer line (18) by making use of a vacuum and compressed air; building up a gradient magnetic field while the sample chamber (11) is charged with the sample (15); and effecting, by the RF coil (13), the emission of an RF pulse series and reception of the magnetic resonance signals for the sample to obtain the magnetic resonance image and the corresponding image spectrum.
