An X-ray detector that includes a sensor matrix and a scintillator arrangement and in which wire elements are spaced apart in layers A and B in order to reduce the crosstalk in neighboring detector elements. The disclosed active inductor devices provide a tunable bandwidth with improved linearity. The system is provided with two or more functional device units realizing a specific function using the input energy and adapted to satisfy an external request using at least one of the two or more functional device units such that supply of energy to the functional device units can be controlled. The present method is useful for treating atherogenic vascular disease and may be combined with other therapies such as statins, inhibitors of cholesterol absorption, niacin, anti-inflammatories, exercise and dietary restriction. The weights are updated by an updating circuit to minimize the error.
