An imaging system can include an antenna apparatus configured to transmit toward and receive from a subject in a subject position, millimeter-wave electromagnetic radiation. To further reduce these disturbances and glitch pulses, a resistor having a resistance value that is based on the impedance of the inductors within a given frequency range is arranged in series between a voltage source and the ignition device of the high-pressure discharge lamp. Any excess modified starch not involved in hemostatic activity is readily dissolved and rinsed away through saline irrigation during operation. When the spectral data is then quantized to reduce bitrate, the earlier phase shifting reduces excess requantization error.
