The endoscopic ultrasound probe system consists of the SP-900 ultrasound processor, the CP-900 control pad and the RS-900 scanner. The system is used in conjunction with a light source and a video processor. The display of the ultrasound processor, the operating elements of the control pad and the probe connector of the scanner are all designed in black in order to ensure easy recognition. The devices are characterised by a rounded construction with smooth surfaces, which are thus easy to clean.
