Abstract: In a method and a magnetic resonance (MR) apparatus for distortion correction of MR-acquired scan data of an object, an entry is made into a computer in order to select desired field of view (FOV), in which scan data of the object under examination (U) is to be acquired. An enlarged field of view (gFOV) is created in the computer by enlarging the desired field of view (FOV) in at least one spatial direction. An MR scanner is operated in order to acquire MR scan data in the enlarged field of view. Distortions are corrected in a data set based on scan data from the enlarged field of view, by applying a distortion correction algorithm to that data set. The corrected data set is reduced in the computer to the desired field of view. The reduced corrected data set is made available from the computer for storage and/or display.

Abstract: In a method and apparatus for time-resolved phase-contrast magnetic resonance (MR) imaging with speed encoding, MR signals are detected with multiple receivers in each of numerous time segments in order to acquire raw data in each of the time segments, in each case for numerous MR images with different speed encodings. Stationary image points and/or non-stationary image points are identified, dependent on the detected MR signals. A mask is defined, dependent on the identified stationary image points and/or the non-stationary image points, wherein the mask is locally variable. The numerous MR images for the numerous time segments are reconstructed from the acquired raw data, wherein the reconstruction occurs in an iterative process and with a temporal regularization, which is dependent on the mask.

Abstract: In a method and magnetic resonance apparatus to acquire diagnostic image data of a contrast agent-filled target area of a patient, a peak time of the test bolus in the target area is automatically determined, from which a wait period is then determined for administering the main bolus. After the main bolus has been administered to the patient, magnetic resonance images of the target area are acquired, and each is analyzed immediately after acquisition thereof to determine whether that image shows arrival of the contrast agent. If and when one of these images shows such arrival, an acquisition protocol is immediately started in order to acquire the diagnostic image data set. If none of these images shows arrival of the contrast agent, the protocol to acquire diagnostic image data is started after the wait period.

Abstract: A lithography tool is calibrated using a calibration substrate having a set of first marks distributed across its surface in a known pattern. The tool is operated to apply a pattern comprising a plurality of second marks at various positions on the substrate, each second mark overlying one of the first marks and being subject to an overlay error dependent on an apparatus-specific deviation. The second marks are applied by multiple exposures while the substrate remains loaded in the tool. An operating parameter of the apparatus is varied between the exposures. An overlay error is measured and used to calculate parameter-specific, apparatus-specific calibration data based on knowledge of the parameter variation used for each exposure.

Abstract: In a method for a rapid determination of spatially resolved magnetic resonance relaxation parameters in an area of examination, a preparation pulse is radiated into the area of examination. During the relaxation of the longitudinal magnetization, spatially encoded magnetic resonance signals are acquired at a minimum of two different points in time using a fast magnetic resonance sequence. At each inversion time, an image data record is reconstructed from the magnetic resonance signals, which are elastically registered to each other. From the recorded image data records, values of magnetic resonance relaxation parameters are spatially accurately determined.

Abstract: A lithographic apparatus applies a pattern onto a substrate using an optical projection system. The apparatus includes an optical level sensor and an associated processor for obtaining a height map of the substrate surface prior to applying the pattern. A controller uses the height map to control focusing with respect to the projection system when applying the pattern. The processor is further arranged to use information relating to processing previously applied to the substrate to define at least first and second regions of the substrate and to vary the manner in which the measurement signals are used to control the focusing, between the first and second regions. For example, an algorithm to calculate height values from optical measurement signals can be varied according to differences in known structure and/or materials. Measurements from certain regions can be selectively excluded from calculation of the height map and/or from use in the focusing.

Abstract: Position errors of the flat-panel detector in the axes system of the radiation penetration system relative to a necessitated position which remain, for example, after a coarse setup of the radiation penetration system are balanced and thus the accuracy of the radiation penetration system is brought almost randomly close to the accuracy which would have resulted if the flat-panel detector had been exactly adjusted mechanically subsequently by executing a geometrical correction of the radiation penetration raw image, so that a change of a projection of the penetrated object in the radiation penetration raw image due to the position error is reduced or corrected.

Abstract: A reticle is loaded into a lithographic apparatus. The apparatus performs measurements on the reticle, so as to calculate alignment parameters for transferring the pattern accurately to substrates. Tests are performed to detect possible contamination of the reticle or its support. Either operation proceeds with a warning, or the patterning of substrates is stopped. The test uses may use parameters of the alignment model itself, or different parameters. The integrity parameters may be compared against reference values reflecting historic measurements, so that sudden changes in a parameter are indicative of contamination. Integrity parameters may be calculated from residuals of the alignment model. In an example, height residuals are used to calculate parameters of residual wedge (Rx?) and residual roll (Ryy?). From these, integrity parameters expressed as height deviations are calculated and compared against thresholds.
