Tungsten alloy collimator is also known as tungsten heavy alloy collimator or high-density tungsten alloy collimator. Collimator is a key component of gamma camera - the most basic imaging equipment in nuclear medicine, and affects the imaging quality. So, it is very important to choose the raw material of collimator. Tungsten alloy has good absorption and shielding performance to 60Co, 137Cs and other strong gamma ray sources, and therefore, it is regarded as the best shielding material for collimators. And tungsten alloy collimator can prevent γ-ray omission from causing permanent harm to medical workers, patients and their family members.

Tungsten heavy alloy collimator, an important part of detector of SPECT system, is a collimator made of high density tungsten-based alloy with composition of W-Ni-Fe, W-Ni-Cu or W-Ni-Cu-Fe. There are a certain number of holes arranged on the collimator. According to the form of the drilled hole, the tungsten heavy alloy collimator is divided into tungsten alloy parallel-hole collimator, tungsten alloy focusing collimator, tungsten alloy converging collimator, and tungsten alloy pinhole collimator.

As a medical radiation shielding material, tungsten alloy shield may be a tungsten alloy collimator, a tungsten alloy isotope container, a tungsten alloy syringe shield, a tungsten alloy shield door, and the like. They are all high-density tungsten alloy parts. You know, the higher the density, the better the radiation shielding performance.

Lead shield is a thing of past. Tungsten alloy X-ray shield, a newly developed poison-free shielding partition, is the future in hospitals or dental clinics, which can fully protect the medical workers and patients from different radiation resources such as X-rays. It has been reported that tungsten alloy X-ray shield is safe as it is non-toxic, fire-resistant and anti-corrosion with premium stability. Also, it features excellent sound insulation properties. And it can create an excellent and robust surface.
