A medical imaging system adaptively acquires anatomical images using a shape adaptive collimator including multiple different portions of X-ray absorbent material automatically adjustable to alter the dimensions of a spatial cross section of an X-ray beam of radiation into a non-rectangular shape, in response to a control signal. In one embodiment the evaluation circuit according to the invention includes a first linear automaton circuit and also a second linear automaton circuit connected in parallel, each having a set of states z, which have a common input line for receiving a data stream Tn. A second portfolio of assets is configured to have performance characteristics similar to those of the index, while having less than 70 percent overlap therewith. Using this information, IP check layer determines how to process a socket call and which layer will take over the socket call.
