Area of Science:

  • Medical Imaging
  • Network Engineering
  • Cardiology

Background:

  • High-bandwidth data transmission is crucial for modern medical imaging.
  • Existing systems often lack scalability and the ability to handle high-resolution, uncompressed cardiac data.

Purpose of the Study:

  • To develop a scalable, high-speed fiber-based network for cardiac imaging.
  • To create a general-purpose review station capable of handling demanding image data.
  • To integrate network and review capabilities with efficient data storage.

Main Methods:

  • Implementation of an Asynchronous Transfer Mode (ATM) based fiber network.
  • Development of a multi-modality review station with loop RAM for high frame rate display.
  • Utilizing a virtual file system for seamless integration of RAID and tape storage.
