Tungsten Alloy Radiation Shielding in PET Equipment

Tungsten alloy radiation shielding in PET (Positron Emission Tomography) equipment is used for γ-ray attenuation, scatter radiation control, and detector protection. High-density tungsten alloy provides effective attenuation of 511 keV γ-rays and can be precision-machined into shielding structures for PET detector modules and other radiation-sensitive areas. CTIA manufactures tungsten alloy shielding components to reduce unwanted radiation interference, improve imaging signal-to-noise ratio and detection accuracy, and meet requirements for precision and long-term operational stability in PET equipment.

1. Features of CTIA’s Tungsten Alloy Radiation Shielding in PET Equipment
(1) Effective γ-Ray Shielding: Attenuates 511 keV γ-rays generated during PET imaging with a density of 16.7–18.8 g/cm³, reducing radiation leakage and scattered radiation.
(2) Reduced Scatter Interference: Controls radiation entering detector regions from non-target directions, reducing background noise and improving PET image clarity and detection accuracy.
(3) Compact Structure: Reduces shielding structure dimensions through high material density, supporting PET detector modules and compact equipment designs.
(4) Precision Machining: Supports turning, Wire Electrical Discharge Machining (Wire EDM), Electrical Discharge Machining (EDM), grinding, and polishing for complex shielding structures and custom-shaped components.
(5) Long-Term Stability: Maintains mechanical strength, wear resistance, and dimensional stability during long-term PET equipment operation.
(6) Lead-Free Material: Eliminates lead and other harmful elements, supporting safe use in medical equipment.
