Abstract: The present disclosure is directed to a motor for a magnetic resonance (MR) tomography room, to a patient table for the MR room, to a MR elastography device, and to a MR tomography device. A MR tomography device for a MR elastography imaging protocol is arranged within the MR tomography room, and includes a rotational drive for supplying rotational energy to power a MR elastography transducer usable during the MR elastography imaging protocol, and a support structure. The rotational drive comprises a terminal for connecting the MR elastography transducer to the rotational drive, and a bearing means configured such that the position of the terminal relative to the support structure is adaptable along a trajectory predetermined by the bearing means. The rotational drive is mounted to the support structure via the bearing means.

Abstract: The present disclosure is directed to techniques for synchronizing a rotational eccentric mass of a gravitational transducer used for a magnetic resonance elastography acquisition with a corresponding magnetic resonance elastography scan carried out by a magnetic resonance imaging system, wherein the rotation of the eccentric mass is driven by a shaft. The method includes starting the rotation of the eccentric mass at a set vibration frequency and the magnetic resonance elastography scan at a set acquisition frequency; determining the rotational position of the shaft; defining the rotational position as first reference position; calculating further reference positions. At the start time of each subsequent acquisition period, determining the current rotational position of the shaft; comparing the determined current rotational position with the theoretically expected reference position and decreasing or increasing the rotational speed of the rotational eccentric mass based on the comparison.

Abstract: A method and system for performing three-dimensional, 3D, magnetic resonance elastography, MRE, using a multi-slice gradient echo, GRE, imaging sequence. Four scans typically required to be performed during MRE, and during four breath-holds, are combined into a single measurement that can be performed during a single breath-hold.

Abstract: This disclosure relates to stethoscope carrying devices and associated components such as clip and/or holder assemblies, systems, methods of manufacture and use.

Abstract: The present disclosure generally relate to a method and system for performing three-dimensional, 3D, magnetic resonance elastography, MRE. In particular, the present disclosure relates to a method and system for imaging an area of a patient using a multi-slice gradient echo, GRE, imaging sequence. Advantageously, the present techniques enable the four scans that are typically required to be performed during MRE, and during four breath-holds, to be combined into a single measurement that can be performed during a single breath-hold.
