Tungsten Alloy Radiation Shielding in SPECT Equipment

Tungsten alloy radiation shielding in SPECT equipment is a key radiation control component used for γ-ray collimation, scatter suppression, and detector signal optimization. CTIA's tungsten alloy radiation shielding effectively attenuates γ-rays and can be precision-machined into collimation and shielding structures to control γ-ray propagation, reduce stray radiation interference, improve imaging quality and detection accuracy, and meet the requirements for precise radiation control and long-term operational stability.

1. Features of CTIA’s Tungsten Alloy Radiation Shielding in SPECT Equipment
(1) Effective Shielding: Attenuates γ-rays with a density of 16.7–18.8 g/cm³, reducing the effects of radiation leakage and scattered radiation on imaging.
(2) Precise Collimation: Precision-machinable into parallel-hole, pinhole, and other collimation geometries to restrict γ-ray incident angles, improving detection signal accuracy and spatial resolution.
(3) Scatter Suppression: Blocks radiation from non-target directions from reaching detector regions, reducing background noise and improving image contrast and lesion detection.
(4) Compact Structure: Reduces component thickness and installation space through high material density while meeting radiation shielding requirements, making it suitable for compact SPECT equipment.
(5) Precision Machining: Supports precision machining, wire electrical discharge machining (Wire EDM), electrical discharge machining (EDM), grinding, and polishing for complex channels, custom-shaped structures, and high-precision shielding components.
(6) Long-Term Durability: Maintains mechanical strength, wear resistance, and dimensional stability under long-term medical equipment operating conditions.

2. Applications of CTIA’s Tungsten Alloy Radiation Shielding in SPECT Equipment
(1) SPECT Collimator Assemblies: Applied in parallel-hole collimators, pinhole collimators, and specialized collimation structures to govern γ-ray propagation paths, improving spatial resolution and imaging accuracy.
(2) SPECT Detector Protective Structures: Applied surrounding detector heads and sensor modules to block stray radiation, enhancing effective signal acquisition quality.
(3) SPECT/CT Hybrid Imaging Equipment: Applied in internal radiation shielding structures to reduce stray radiation impact, increasing multimodality fusion image stability.
(4) Nuclear Medicine Imaging Systems: Applied in SPECT diagnostic systems for bone imaging, myocardial perfusion, and oncology examinations, raising medical image quality and diagnostic reliability.
