A control device for a medical imaging system drives a signal source and a detector so that the detector registers raw data of an object. The invention also relates to a method for producing the same and to the use thereof. The computer receives user commands, and based on the commands, moves the actuator to a selected one of a plurality of different positions around the tissue-compression fixture and then extends the probe into the patient. An embodiment of a circuit for maintaining performance of a micro-electromechanical switch includes first and second signal line nodes, sensing circuitry coupled to the signal line nodes and adapted to sense a performance parameter value of the switch, and control circuitry operably coupled to at least one terminal of the switch. Decimation of data points are performed based on the indices without retrieving all the data sets from the database, reducing the data access time for returning a query result. The method includes receiving geo-location data associated with the monitoring device.
