Tube Housing: Maximum voltage 40-150 kV, Weight 5-50 kg

Q: What is the primary function of tube housing in X-ray systems?

The tube housing provides radiation shielding to protect operators, contains the vacuum environment for the X-ray tube, dissipates heat, and provides structural support for internal components.

Q: How often should tube housing be inspected for radiation safety?

Annual radiation leakage tests are recommended per IEC 60601 standards, with visual inspections during routine maintenance every 6 months for cracks, oil leaks, or connector damage.

Component Specifications

Definition

The tube housing is a critical component in X-ray source tubes that serves as a radiation-shielded enclosure containing the X-ray tube insert. It provides mechanical protection, thermal management through cooling systems, electrical insulation, and radiation containment to ensure safe operation. Typically constructed with lead-lined steel or aluminum alloys, it includes high-voltage connectors, cooling ports, and mounting interfaces while maintaining precise alignment of internal components.

Working Principle

The tube housing operates by containing the X-ray generation process within a shielded environment. It absorbs scattered radiation through lead lining, dissipates heat via oil or air cooling systems, maintains vacuum integrity for the tube insert, and provides electrical insulation between high-voltage components and external structures. The housing's design ensures radiation is directed only through the designated window while preventing leakage.

Materials

Primary housing: Lead-lined steel (1.5-3mm steel with 2-5mm lead equivalent) or lead-impregnated polymers. Cooling system: Copper tubing with dielectric oil or aluminum fins for air-cooled models. Electrical insulators: Ceramic or glass feedthroughs. Seals: Viton or silicone gaskets.
