CT Tungsten Alloy Collimator

CT tungsten alloy collimator is precision component designed for X-ray beam control, beam shaping, and scatter suppression in CT (Computed Tomography) equipment. CTIA’s tungsten alloy collimator uses precision slits, collimation holes, and positioning structures to accurately control X-ray beam width and shape while providing effective shielding, compact structure, precision machining, and long-term dimensional stability. It meets CT equipment requirements for precise beam control and local radiation protection based on scan slice thickness, beam width, and detector configuration.

1. Features of CTIA’s CT Tungsten Alloy Collimator
(1) Effective Shielding: A density of 16.7–18.8 g/cm³ provides good X-ray attenuation, enabling effective shielding with relatively thin structures.
(2) Precise Collimation: Precision-machinable with tight-tolerance slots, collimation apertures, and complex contours to accurately govern X-ray beam width, orientation, and profile.
(3) Structural Stability: High mechanical strength and good dimensional stability support CT equipment operation under rotation, vibration, and long-term service conditions.
(4) Lead-Free: Lead-free material eliminates lead pollution hazards, featuring polishable and easy-to-clean surface finishes.

2. Applications of CTIA’s CT Tungsten Alloy Collimator
(1) Front and Rear Collimation Systems: Used on the X-ray tube side and detector side to control scan slice thickness and beam width while reducing unnecessary irradiation.
(2) Multi-leaf Collimator (MLC): Used in dynamic multi-leaf structures to adjust beam shape and control radiation dose for specific imaging and radiotherapy applications.
(3) Detector Collimator Grids: Used in front of detectors and in ring-shaped collimation components to filter scattered radiation and improve image signal-to-noise ratio.
(4) Local Collimation at X-Ray Tube and Gantry: Used in X-ray tube outlet collimator covers and local shielding components inside the rotating gantry for beam shaping and local radiation protection.
(5) Advanced and Hybrid CT Systems: Used in dual-source CT, photon-counting CT, and CT-MRI hybrid systems where high-precision or non-magnetic collimation is required.
