In a magnetic resonance imaging method and apparatus, magnetic resonance data are acquired using a zoomed method, and reconstruction of the image of the examination subject is undertaken using a parallel imaging reconstruction method. A deviation between the detected number and a target number of electric discharge pulses is obtained. In another embodiment, the body is formed from an absorbent material that absorbs a fluid, such as a cleaning solution, that can clean andor disinfect the interior walls of the pipe or track. A generating unit is configured to generate a simulation scenario, depending upon the first criterion. The capture structure operably passes through a central bore of the retaining ring while the spline passes through a suitably shaped channel so that the spline becomes positioned above the head at which time the shank is rotated appropriately and the shank is drawn back downwardly so that the spline engages and seats in the capture recess. The braided construction of the central core and reflective sleeve, together with the configuration of the electroluminescent wire, resist tensile, twist and torsional forces, enabling reliable emission of omnidirectional illumination and reflectivity.
