Introduction This section describes the electronics of the system and how the echo data flows through it.
Operating
System
The operating system used on the Host and the Signal and Image-Processing (SIP) motherboards
is Microsoft Windows XP Embedded (XP-E). The embedded XP version allows customization of
components and system behavior. Much of the operating system is hidden from the user, as the
Philips applications use XP-E as a vehicle for implementing system behavior through custom
graphical user interfaces (GUI).
The operating system on the host is primarily used for system interaction with the user or net-
work and as an application platform for implementing the iE33 operation and behavior.
The SIP operating system is configured for headless operation (no graphics subsystem). The pri-
mary functions of the SIP operating system include:
• Process estimate data to native format data (scan converted but not scaled to display size)
• Process estimate data flow components to sweeping display data and digital Doppler audio
• Process estimate data to M-mode sweeping display data
• Implement the Cineloop function for save/recall/review
System
Functional
Architecture
The Applications layer comprises software to perform administrative functions and miscella-
neous non-imaging tasks necessary to operate the ultrasound system.The Virtual Ultrasound
System comprises all proprietary technologies developed by Philips that are involved in ultra-
sound imaging and the related physiological signals. These include hardware, firmware, and soft-
ware. The Platform layer comprises the hardware and infrastructure required to run the
applications and virtual ultrasound systems.
