Cobham ASICs for Medical Applications

Custom ASICs for the Medical Industry for Ultrasond and x-Ray Imaging.

Medical X-Ray Imaging

Providing your HiRel Databus for HiRel Applications

Cobham Semiconductor Solutions ASICs (formerly Aeroflex) has expertise in the Medical X-ray Imaging market segment with products such as:

  • Medical X-ray Computed Tomography (CT) Readout ASICs
  • Medical X-ray Flat Panel Radiography Gate Drivers and Readout ASICs

Cobham Experiences

Cobham has been providing the latest innovations in Digital and Mixed-Signal ASICs for over 30 years for HiRel applications. Starting with  0.6µm (we still support 5V) to now 90nm technologies, produced in State-of-the-Art foundries worldwide, we reach new levels for our customers. In 2000 we entered the commercial/industrial/medical mixed-signal marketplace with mixed-signal IC design services and ASICs. This diversification expanded into the data-networking marketplace and complements current product offerings in the high-reliability standard product and ASIC areas.

Cobham is a fab-independent semiconductor supplier with the flexibility to choose among numerous world-class processes that offer exceptionally high performance at the lowest cost for your design. We exploit the advantages of third-party wafer fabrication and have installed our own process modules into commercial foundries. We boast a high rate of first-pass success.

Cobham Technology Expertise

Cobham's four Design Centers are staffed with a team of mixed-signal design experts with numerous years of IC design experience and has successfully designed and released into production custom mixed-signal ASIC's for commercial, industrial, telecommunications, medical, military, and space applications.

Medical X-ray Computed Tomography (CT) Readout ASICs

Medical X-ray Computed Tomography
  • Signal Chain
    • Photodiode Array → Cobham IC → Data Processing → Image Reconstruction
  • Size/Space
    • Standard Product solutions didn't exist with enough channels to address the application
  • Power
    • Even the standard product architectures, if integrated, would have much too high a power density for a CT gantry
  • Regulatory Pressures
    • FDA demanding lower dose imaging, especially for children
    • Lower dose requires lower noise
  • Environment
    • To meet lower noise demands, have to move read-out ASIC into the x-ray beam
    • Solution needs total ionizing dose tolerance
  • Operation
    • Cobham mixed-signal ASIC is at the front end of the imaging system
    • Critical low noise, high linearity performance is required to reduce imaging artifacts
    • Concurrent data conversion on all channels, 20 bit output
    • Best in class power efficiency reduces thermal noise in signal path
    • Low Radiation Exposure to patient demands low noise performance
  • Value Proposition
    • Radiation Tolerant design allows the ASIC to be in the X-ray beam for noise reduction
    • High channel count ASIC is needed for increasing imaging resolution
    • Low noise and High channel to channel isolation

Medical X-ray Flat Panel Radiography Gate Drivers and Readout ASICs

Medical X-ray Flat Panel Radiography Gate Drivers
  • Signal Chain
    • X-ray Sensor Panel → Cobham IC → Data Processing → Image Reconstruction
  • Operation
    • Cobham mixed-signal ASIC is at the front end of the imaging system
    • 128 channel, robust flip-chip on flex packaging process
    • Best in class power efficiency
  • Value Proposition
    • Radiation Tolerant design allows the ASIC to be in the Radiation Therapy beam
    • High channel count ASIC is needed for increasing imaging resolution
    • Low noise and High channel-to-channel isolation
