Abstract: The invention relates to a method for testing quality of an object in a real environment using a camera, an optical display device, and a processing apparatus, the method including the following steps: defining a test geometry and a reference geometry in a computer-assisted data mode; defining a test pose, in which the camera should be placed by the user as target positioning for a quality test to be carried out of the object to be tested; and visualizing the test pose on the optical display device. In a second phase, at least one image of the real environment is captured by the camera, the pose of which camera is in a range that includes the test pose, and the test geometry and the reference geometry in the image are tracked. Furthermore, a pose of the tracked test geometry in relation to the reference geometry and at least one parameter are determined on the basis of how the pose of the tracked test geometry is in relation to a target pose of the test geometry defined within the data model.

Abstract: An evacuation station for collecting debris from a cleaning robot includes a controller configured to execute instructions to perform one or more operations. The one or more operations includes initiating an evacuation operation such that an air mover draws air containing debris from the cleaning robot, through an intake of the evacuation station, and through a canister of the evacuation station and such that a receptacle received by the evacuation station receives at least a portion of the debris drawn from the cleaning robot. The one or more operations includes ceasing the evacuation operation in response to a pressure value being within a range. The pressure value is determined based at least in part on data indicative of an air pressure, and the range is set based at least in part on a number of evacuation operations initiated before the evacuation operation.

Abstract: In a method and magnetic resonance apparatus for reconstructing an MR image of a volume segment within an examination object, MR data within the volume segment are acquired according to a separation method by MR data for a k-space line being acquired respectively in steps while a readout gradient is activated in the same readout direction. An image of a first substance and an image of a second substance are thereby reconstructed. A shift length, by which the image of the first substance and the image of the second substance are displaced relative to one another due to the chemical shift in the readout direction is determined. The image of the first substance and/or the image of the second substance is shifted as a function of the shift length, to compensate for the relative displacement between the images of the first and second substances in the readout direction due to the chemical shift. An MR image is generated by combining the images of the first and second substances.

Abstract: A method for shimming a magnetic field in a magnetic resonance tomography (MRT) device includes determining a field of view region for an object under examination. Determining the field of view region includes adapting the field of view region automatically to a region of the object under examination to be examined by the MRT device. Before the MRT device records an image, an adjustment measurement of the magnetic field is performed. A field map of the magnetic field of the field of view region is defined based on the adjustment measurement. A shimming of the magnetic field is implemented based on the field map.

Abstract: A method includes recording a magnetic resonance (MR) spectrum with the aid of a high frequency (HF) coil and a magnetic resonance tomography (MRT) device. A static magnetic field results in a recording volume of the MRT device. The method also includes an automatic analysis of the MR spectrum by searching for two resonant signals in the form of a fat peak, a water peak, and a minimum between the fat peak and the water peak. Such an automatic analysis is used for an automatic decision as a function of a predeterminable criterion, as to whether a series, including a plurality of acts, or a single act is performed. The homogeneity of the static magnetic field is adjusted with the aid of at least one shim coil of the MRT device, and an HF pulse is calculated for fat saturation as a function of the result of the search.
