Cathode Ray Concentrating/Focusing/Directing TRIZ Cases

Electric or magnetic beam deflection redirects electrons to desired focal spots, raising X-ray packing density and compensating for failed cathodes.

Electromagnetic focal spot translation tailors CT illumination fields to patient anatomy, reducing dose without moving filtration hardware.

A reference fixture and edge detection measure X-ray tube focal spot to port distance accurately, improving image sharpness and limiting exposure.

Real-time focusing voltage or current adjustment keeps X-ray focus size stable during tube voltage switching, preserving contrast and resolution.

A widening electron-optics opening passively stabilizes beam focus in compact X-ray tubes, cutting power use and focal spot drift.

Power control and beam steering cut CT voltage-switching time while suppressing X-ray emission during low/high mode transitions.

A 2D periodic electron beam path spreads heat on the tungsten target, enabling faster field shaping and higher radiotherapy dose rates.

Steering the electron beam across segmented targets and shield walls shapes X-ray direction for conformal IORT with longer source life.

Electron beam steering across segmented target pedestals shapes X-ray direction and dose delivery while extending source life in IORT.

An asymmetric multipole deflection unit makes electron distribution on the focal track more uniform, cutting thermal load and extending X-ray source life.

During cathode-adjustment electrode discharge, electron beam deflection shifts the focal spot to protect the target and sustain X-ray generation.

Dual-stage steering keeps the electron beam centered through the lens, stabilizing x-ray spot position and reducing target burn-in.
