Tungsten Alloy Radiation Shielding in CT Equipment

Tungsten alloy radiation shielding provides high-density shielding for X-ray protection, beam control, and scatter suppression in CT equipment. Radiation shielding performance is closely related to material density. Tungsten alloy has high density and high atomic number, providing effective attenuation of X-rays and allowing more compact and thinner structures under the same shielding requirements. CTIA can precision-machine different types of tungsten alloy shielding parts according to the structures of X-ray tubes, collimation systems, and detectors, balancing compact design, radiation protection, and precision assembly requirements.

1. Features of CTIA’s Tungsten Alloy Radiation Shielding in CT Equipment
(1) Efficient Compact Shielding: A density of 16.7–18.8 g/cm³ provides effective attenuation of X-rays generated by CT equipment, allowing more compact structures under the same shielding requirements and helping optimize internal equipment space.
(2) Precision Beam Control: Good machinability enables high-precision collimation holes, ring structures, and leaf structures to accurately control X-ray beam width and irradiation range while reducing unwanted scattered radiation.
(3) Good Structural Stability: High strength and relatively low thermal expansion allow the shielding parts to withstand CT gantry rotation, vibration, and temperature rise during operation while maintaining good dimensional stability over long-term use.
(4) Precision Machining: Supports CNC turning, milling, grinding, and wire EDM processes, accommodating complex internal cavities, curved profiles, and mounting features based on equipment specifications to satisfy precision assembly requirements.
(5) Lead-Free and Environmentally Safer: Lead-free and non-radioactive, eliminating pollution and toxicity hazards associated with traditional lead shields, making them ideal for long-term use in medical devices.

2. Applications of CTIA’s Tungsten Alloy Radiation Shielding in CT Equipment
(1) X-Ray Tube Assembly: Used in local shielding structures around the X-ray tube to reduce X-ray leakage in unwanted directions.
(2) Collimation System: Used in pre-collimators, post-collimators, and related beam-limiting structures to control the propagation direction and irradiation range of X-rays.
(3) Detector Assembly: Used for local shielding around the detector and adjacent areas to reduce the influence of scattered radiation on the detection system.
(4) Inside CT Gantry: Used in local radiation shielding structures inside the gantry to provide compact shielding within limited space.
(5) CT System Auxiliary Components: Used for shielding covers, shielding blocks, and protective structures around X-ray-related components to meet overall radiation protection requirements.
