Tungsten Alloy Collimator

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 alloy collimators are mainly used to achieve spatial positioning, so that gamma rays from different spatial parts are irradiated to specific positions of the scintillator. In other words, tungsten alloy collimator can not only ensure that the gamma rays come out of the designed route to achieve the detection effect, but also can shield and absorb the excess gamma rays.
