Product Features
This 120kV NK-R103N collimator features excellent radiation shielding performance with low X-ray leakage, meeting strict international radiation safety standards. It supports a wide adjustable radiation field, from tiny 3×3cm up to 43×43cm at SID=100cm, adapting to different body parts imaging requirements.
The built-in light localizer provides high illuminance over 180 lux, with a 30-second lamp delay function, allowing operators to preview the exposure area clearly before X-ray activation. High light-field alignment accuracy ensures the visible light area matches the actual X-ray beam precisely, lowering misalignment risks.
Compact and lightweight at only 2.6kg, the collimator is easy to mount on portable X-ray units. The high contrast ratio guarantees stable and clear light field display even under bright ambient environments.
Benefits
By confining X-ray beam only to the target imaging region, this collimator effectively cuts scattered radiation, reduces radiation exposure for patients and operators, and enhances radiographic image contrast. It is a reliable beam control accessory for portable and mobile X-ray diagnostic systems up to 120kV.
