Dental/Medical X-ray Tubes
Dental/medical X-ray tubes (Marked "D") are mainly used in mobile and small portable dental systems and general medical systems.
Dental/medical X-ray tubes are stationary anode X-ray tubes, and are available in a variety of types including two-electrode tubes; three-electrode (self-bias focusing) tubes; single-focus tubes; and double-focus tubes. In an effort to keep X-ray generators small and light-weight, some tubes are equipped with an insulating cylinder and an X-ray-shielding lead cylinder.

♦Notes
- DG: Self-bias tube; DF: Double focus tube
- Some tubes are self-grounded
S -- Self-rectified; SW -- Single-phase full-wave rectification; C -- Constant voltage; CB -- Constant voltage with self-bias; SB -- Self-rectified with self-bias - Nothing -- Insert tube only; S -- with an insulating cylinder; SB -- with an insulating cylinder and a lead cylinder
