摘要： 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.

摘要： 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.

摘要： The invention relates to a method for making a micro- or nano-scale patterned layer of material by photolitography, comprising steps of: positioning a photomask between a light source and a layer of light sensitive material, said mask comprising a support and a layer of micro- or nano-light focusing elements fixed to the support, activating the light source so that the light source emits light radiations through the mask towards a surface of the layer of light sensitive material, developing the layer of light sensitive material so as to obtain the micro- or nano-scale patterned layer of material, wherein, during exposure of the layer of light sensitive material to light radiations, the photomask is positioned relative to the light sensitive layer so that the distance between the surface of the light sensitive layer and the layer of micro- or nano-light focusing elements is greater than a back focal length of the micro- or nano-light focusing elements.

摘要： An acousto-optic imaging method in which light waves and unfocused acoustic waves having various directions of propagation m are emitted in a medium, by spatially modulating the amplitude of the ultrasonic transducers of an array of transducers according to several periodic spatial amplitude modulations j, and the resulting optical signal Smj(t) is captured. For each direction of propagation m, the signals Smj(t) are spatially demodulated in order to determine a signal Sm(t) used to reconstruct the image of the medium.
