Testing a Display Device Invention for Digital Mammography Workstations.

摘要

Purpose: Investigator was to test an invention in electron optics that might allow development of a very high-resolution cathode ray tube (CRT) suitable for digital mammography workstations. Scope: The invention solves a very old problem in electron optics and is patented. The invention allows deflection of a wide beam into large angles using electric fields with little or no acquired aberrations. Major findings: This project was successfully completed. The invention worked as predicted and results have been published in Journal Vacuum Science and Technology - B 20(6): 2678-81, Nov/Dec 2002. Results and Significance: While it is now technically possible to develop such a CRT display device1 a new flat panel display was announced by IBM that seems to fulfil the mammography application needs. Thus while this project was a technical success, this particular application has been fulfilled by another company's product. We are now looking for other applications where our technology can make a contribution. Fortunately, there are many opportunities ranging from electron beam lithography to isotope separation and mass spectrometry.
