The DC Power is self-regulated. If a voltage is outside the specified range, it means that something is wrong, either with the power supply itself or with a unit connected to that sp ecific power outlet.

GE HEALTHCARE DIRECTION FC091194, REVISION 11 VIVID 7 SERVICE MANUAL 5 - 2 Section 5-2 - General Information Section 5-2 General Information 5-2-1 Introduction The Vivid 7 ultrasound scanner can be used with both phased array and linear array ultrasound probes and Doppler (Pedof) probes. The system can be used for: • 2D Gray Scale and 2D Color Flow Imaging • M-Mode Gray Scale Imaging • Color M-Mode • Doppler • 4D (Realtime 3D, introduced 2004) • Different combinations of the above modes Vivid 7 is a digital beamforming system. Signal flow travels from the Probe Connector Panel to the Front End Electronics, then to the Back-End Processor, an d finally, the results are displayed on the monitor System configuration is stored on the hard drive (inside the Back-End Processor (BEP)) and all necessary software is loaded from the hard drive on power up. A Physio module, the Patient I/O, is incorporated in the Back-End Processo r (BEP) to provide ECG signals to synchronize cardiac ultrasound image acqu isition. Other analog signals, from devices such as treadmills (e.g. ECG an d phono), are also processed by the Patient I/O.

GE HEALTHCARE DIRECTION FC091194, REVISION 11 VIVID 7 SERVICE MANUAL Chapter 5 - Components and Functions (Theory) 5 - 3 5-2-2 Signal Flow The TX board(s) in the Front-End Processor, generat es the strong bursts transmitted by the probes as ultrasound into the body. The Transmit bursts are rout ed from the TX board via the XD bus to the Relay board where the ultrasound probes are connected. Weak ultrasound echoes from blood cells and body st ructure are received by the probes and routed via the Relay board and the XD bus to the RX board. The RX board amplifies these signals and converts them to a digital signal. After amplification and digital signal processing in the Front-End electronics, the signal is transferred via the PCI bus to the Back-End Processor where the signal is converted to video. The video signals are connected to the monitor, to the Cassette Video Recorder (VCR) and the internal video printers. The signals are also converted so they can be connected to Digital Printers. 5-2-3 System Configuration and Software System configuration is stored on a hard disk drive inside the Back-End Processor. At power up, all necessary software is loaded from the hard disk. 5-2-4 Operator Panel The user initiates system operation via the Operator Panel which contains an alphanumeric keyboard and a control panel with controls for TGC and the LCD displays. 5-2-5 The Electronics Vivid 7 internal electronics are divided into two card cages; • Front-End Processor (FEP) The FEP is sometimes called “Front-End Card Cage” or only “Card Cage”. • Back-End Processor (BEP) Interconnecting signals and power distribution between the different modules are routed via the backplane, via cables, via the Internal I/O and the External I/O.
