Chassis-Based Architecture
Large imaging systems have used chassis implementations to provide flexibility/scalability, offering hospitals/clinics multiple options at various price points. These systems are also used to accelerate complex hardware and software development across multiple platforms, teams, and locations.
Diagnostic imaging requires many electronic subsystems and specialized components to acquire and recreate the spectacular life saving pictures of the human body. These subsystems must meet the following requirements:
- Accommodate multiple cards for data acquisition, processing, control, and switch interconnects
- Transfer large amounts of data through proprietary parallel bus structures
Now you can implement commercial off-the-shelf (COTS) or proprietary chassis backplane architectures (see Figure 1) using standardized serial implementations with integrated serial transceivers (e.g., PCI Express (PCIe) on Stratix® II GX FPGAs), which allow:
- Significantly increased subsystem data transfer rates
- Lower development costs and a smaller equipment footprint
- Higher performance, homogenous blade servers using CPUs coupled with FPGA coprocessing cards
Homogeneous processing architectures provide a scalable, ready-to-use hardware platform including user interface, storage, and connectivity with the capability to add algorithm acceleration through FPGA add-on cards. The OEM adds application-specific analog interface cards to complete the electronics of the system. See Figure 1.
