A vehicle brake assembly includes a first brake housing portion having an assembly opening formed through a lower face. Because an atrial tachyarrhythmia, such as atrial fibrillation typically causes significant variability in the ventricular heart rate, resulting in potentially proarrhythmic conditions. The present invention reduces heat generation at the anode as much as possible and enables uniform illumination without providing a diffuser. The method insures that for every primary screen density, the closest possible secondary screen density is used when the same digital value is specified. The ends of the first connecting member can be secured to each other to form a ring or loop. A number of image acquisition parameters are determined and, using the image acquisition parameters, an achievable image quality of the image exposure is concluded under consideration of an apparatus variable.
