Abstract
Normally a cathode ray monitor cannot be employed in a chamber which is shielded against high-frequency interference because of the disturbances in the otherwise shielded chamber produced by the operation of the cathode ray monitor. A display arrangement employing a cathode ray monitor is disclosed, which can be used in a shielded chamber, including a projection picture tube disposed outside of the shielded chamber, a projection disposed inside of the shielded chamber, and an optical imaging arrangement disposed in the beam path between the projection picture tube and the projection screen, the beam path extending through a light-transmissive port in a wall of the shielded chamber.
Claims5
A display arrangement for use with a shielded chamber containing interference-producing and interference-susceptible components for conducting an examination of a subject, said display arrangement comprising:
- computer means disposed outside of said shielded chamber for generating user interface information useable in conducting said examination;
- a projection picture tube disposed outside of said shielded chamber, said projection picture tube being connected to said computer means and generating user interface images corresponding to said user interface information generated by said computer means;
- a projection screen disposed inside of said shielded chamber, said projection picture tube and said projection screen defining a beam path therebetween;
- imaging means disposed in said beam path for imaging said user interface images generated by said projection picture tube onto said projection screen;
- and
- a light-transmissive port disposed in a wall of said shielded chamber through which said beam path passes.
