Abstract: A method is for processing parameters of a machine-learning method for providing a correction dataset for motion correction of a CT image dataset of an object that moves during recording thereof. A training dataset with a number of reference image datasets for introduction into the machine-learning method is provided. Iteration is performed. In each of the iteration steps, a correction dataset is determined for each of the reference image datasets via the machine-learning method and a result of a cost function dependent on the correction datasets determined in this iteration step is ascertained. The iteration is terminated or a parameter of the machine-learning method is altered in dependence on the result of the cost function. A reconstruction method further uses the processed machine-learning method.

Abstract: A turbine airfoil (10) includes an elongated hollow body (26) defining a radial cavity (T1, T2) positioned in an airfoil interior (11). A pair of radial flow passes (B,E/C,D) incorporating near-wall cooling (72, 74) channels are formed on opposite sides of the elongated hollow body (26), which are in serial flow relationship conducting a coolant in opposite radial directions, forming a serpentine cooling path (60a, 60b). A downstream radial flow pass (C, D) of the serpentine cooling path (60a, 60b) is fluidically connected to the radial cavity (T1, T2). Relatively heated coolant from the serpentine cooling path is directed into the radial cavity (T1, T2) to warm the elongated hollow body (26). The coolant is subsequently discharged via impingement openings (90) on the elongated hollow body (26) into first and second impingement volumes (102, 104) that respectively adjoin the pressure and suction side walls (16, 18).

Abstract: In a method for computing MR images of an examination object that performs a cyclic movement, MR signals are detected over at least two cycles of the cyclic movement. In each of these cycles, data for multiple MR images are recorded. Over these cycles, a magnetization of the examination object that influences the MR images approaches a state of equilibrium in a second of these cycles is closer to the state of equilibrium than in a first of these cycles. Movement information for various movement phases of the cyclic movement of the examination object is determined using the MR images from the second cycle, with movement information of the examination object determined for each of the various movement phases. Movement correction of the examination object is carried out in the MR images of the first cycle using the movement information determined in the second cycle.
