Craig S Nunan: Mutileaf collimator for radiotherapy machines. Varian Associates, Stanley Z Cole, Gerald M Fisher, Kenneth L Warsh, September 19, 1989: US04868844 (207 worldwide citation)

In a radiation therapy machine it is desirable to produce irregular radiation field shapes in order to shield critical organs not invaded by the tumor. A multileaf collimator is formed of a multiplicity of heavy metal bar leaves driven relative to frames which are driven relative to jaws of a rectan ...

Marvin Chodorow, Robert S Symons: Mode suppression means for gyrotron cavities. Varian Associates, Stanley Z Cole, Richard B Nelson, August 9, 1983: US04398121 (150 worldwide citation)

In a gyrotron electron tube of the gyro-klystron or gyro-monotron type, having a cavity supporting an electromagnetic mode with circular electric field, spurious resonances can occur in modes having noncircular electric field. These spurious resonances are damped and their frequencies shifted by a c ...
