needs.
EMBEDDED SYSTEMS
Matching
Embedded PC Boards to Medical Applications
Glenn S. Kubota
When properly selected, embedded PC boards can reduce the length
of a design cycle and increase the performance or number of features in a product.
Multiprocessing
Architectures for Medical Imaging Systems
Iain Goddard

The memory and I/O bandwidths of multicomputers make them the necessary choice for the most sophisticated imaging applications.
Reconfigurable
Computing for 3-D Medical Imaging
Stuart Newton and David Vornholt
Field-programmable gate arrays in combination with cpus provide a flexible system that can be upgraded easily, quickly, and cheaply.
NETWORKING
Network-Enabling Technology for Medical
Equipment: Build or Buy?
Tom Armbrust
Manufacturers
facing this decision must balance cost considerations and time-to-market requirements
while appraising all the available technology options.
SENSORS
A
New Technology for Pressure Transducers
Duane Tandeske
Using microcontrollers rather than operational amplifiers, digitally compensated
transducers offer performance, space, and cost benefits.
MEDICAL EMC
The
Hidden Schematic: EMC Threats in Medical Power Supplies
William D. Kimmel and Daryl D. Gerke
Many EMC problems in power supplies—especially for medical electronics—are
hidden in parasitic elements. Such factors must be included in early modeling.
EMI RISK
Electromagnetic
Interference in Medical Devices
Kok-Swang Tan, Irwin Hinberg, and Jesuzette Wadhwani
An overview of EMI issues can help develop suitable electromagnetic compatibility
requirements and other solutions to minimize risk to patients.
DISPLAY TECHNOLOGIES
The
video display has become increasingly important as healthcare providers not
only receive information via the display but also use it to provide input to
the medical device. Continued advancements in flat-panel displays allow designers
more options. Performance characteristics such as better luminescence and improved
contrast are often critical in medical device design. Two experts in this field
examine the advantages of flat-panel technologies, particularly when compared
to cathode ray tube technology. And, as touch screens replace keyboards in more
and more medical devices, it is critical to understand these technologies to
determine which is best for use in medical equipment. This overview focuses
on five-wire resistive touch screens, which are constructed to provide accuracy
and durability—key performance criteria for medical applications.
