摘要： The invention relates to a magnet assembly for an MRI system with an improved RF screen. The RF screen is located between an RF coil assembly and a gradient coil assembly and comprises multiple layers of a screening foil. The screening foil comprises a dielectric foil and a plurality of conductive patches which are applied to a first side of the dielectric foil. By wrapping up the screening foil several times an RF screen comprising a plurality of capacitors is created, which effectively shields RF radiation from the gradient coil assembly. Further the shape and arrangement of the conductive patches is chosen such that the flow of eddy currents in the conductive patches caused by a gradient magnetic field is reduced.

摘要： A magnetic resonance examination system comprising a main magnet for applying a uniform static magnetic field. An active shim system applies shim magnetic fields to correct for inhomogeneities of the static magnetic field. A shim driver system activates the active shim system on the basis of B0 -shim settings. A trained machine-learning module is trained to return the B0-shim settings from one or more actual load parameters. The magnetic resonance examination system may further comprise an RF transmit system with RF antenna elements and an RF driver system to activate the RF antenna elements for applying a (B1) radio frequency field having a predetermined spatial distribution. An RF shim system to control the RF driver system to apply shim radio frequency fields to correct for deviation of the radio frequency field's spatial distribution from the predetermined spatial distribution on the basis of RF-shim settings. A trained machine-learning module trained to return the RF-shim settings from one or more actual load parameters.

摘要： A method (100) is disclosed for determining a signal indicative of a state of a subject during a diagnostic imaging or therapeutic procedure based on camera observation. The method comprises acquiring (101) camera images from a camera configured to monitor a body part of the subject during the procedure, e.g. via a reflection thereof in a reflective surface. The method comprises detecting (102) a shape or contour of the reflective surface in at least one acquired camera image to define a region of interest in the image that contains image information corresponding to the body part of interest, and segmenting (103) the region of interest in one or more camera images to select pixels that correspond to a feature of the body part of interest. The method also comprises determining (105) the signal indicative of the state of the subject from the selection. The invention further relates to a corresponding device, system and computer-program.
