A system and method are provided for displaying images of first and second image data in which geometry data is transferred from an ultrasound imaging detector to an image combination device in addition to first image data to reduce the need for calibration and registration. The auxiliary processor may modify one or more definition parameters of the programmable processing unit based on determining that the load value of the programmable processing unit is lower than a threshold value. In an upstream portion of the communication path, the optical network equipment that can compensate the optical signal characteristic for each wavelength determines the necessity to eliminate a deviation between wavelengths and the position to eliminate it, using the optical signal characteristic index and the control necessity determination threshold. A method for implanting a pacing device at a target coronary sinus tissue location, wherein the target can be the posterior LV summit.
