CT tungsten alloy collimator refers to a tungsten alloy collimator used in CT scanners, mobile CT scanners and other CT equipment, which can play a role in radiation protection and radiation guidance. Wherein, the reason why tungsten alloy collimator has a radiation protection effect is that: tungsten alloy has high density, so it has excellent absorption capacity for X-rays. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html There are two tungsten alloy collimators in a CT scanner, a tungsten alloy collimator in X-ray…

Tungsten alloy collimator reduces radiation levels in CT scanning. Tungsten alloy collimator not only has the ding of collimation (X-ray guidance), but also absorbs scattered X-rays (X-ray shielding), so it can improve the image quality and can also reduce the radiation levels of CT scanning to a certain extent. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html The typical radiation dose associated with a standard CT scan ranges from 1 to 14 mSv, equivalent to the total annual dose of natural radiation that…

Tungsten alloy collimator provides the perfect solution for radiation shielding and collimation in nuclear medicine. Because tungsten alloy has excellent radiation attenuation properties, such a collimator has a reduced volume than traditional lead collimator, while it can still effectively shield harmful X-ray and gamma radiation. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html In pre-molecular imaging, tungsten alloy collimator is used to direct radiation emitted by the subject onto a detector, and to minimize the number of stray photons. Tungsten alloy collimators include…

PET-CT tungsten alloy collimator uses small amounts of radioactive materials called radiotracers or radiopharmaceuticals, a special camera and a computer to evaluate organ and tissue dings. By identifying changes at the cellular level, PET-CT may detect the early onset of disease before other imaging tests can. In general, the radioisotope used for PET-CT examination is fluorine 18. Therefore, the main radioactive hazards of this inspection are gamma rays and X-rays. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html PET-CT tungsten alloy collimator is…

γ camera tungsten alloy collimator now mostly refers to the SPECT collimator, rather than the traditional gamma camera collimator where the head cannot rotate. SPECT is a relatively new imaging system compared to traditional gamma cameras. While in any gamma camera, the role of the tungsten alloy collimator is radiation guidance and radiation protection. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html So, what is the main role of tungsten alloy collimator in the gamma camera? According to a certain rule, the distribution…

SPECT tungsten alloy multipinhole collimator is tungsten alloy collimator applied for nuclear medicine tomographic imaging technique using gamma rays. And sometimes SPECT tungsten alloy multipinhole collimator is an integrated SPECT collimator for laboratory rats. Tungsten alloy multi-pinhole collimator is an indispensable four-dimensional accurate quantitative imaging and animal experiment auxiliary system. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html Features of SPECT Tungsten Alloy Multipinhole Collimator 1. One-piece multi-pinhole collimator, with circular tube design, axial movement to realize imaging of large and small mice…

Tungsten alloy collimator is a device used to restrict the photon acceptance angle to provide positional information for detected photons. SPECT tungsten alloy collimator is a thick sheet of tungsten alloy of high atomic number, pierced by an array of holes. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html In theory, only photons that traverse these holes without striking the septa between them can be detected. In practice, some photons penetrate the septa and are detected, degrading the resolution and contrast of the…

Tungsten alloy collimator is an important part of a gamma camera (γ camera). And it plays the role of radiation guidance (collimation) and radiation protection (reducing the patient’s exposure to gamma rays) on the core component of the gamma camera. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html How does a gamma camera work? Radioactive nuclides such as 99mTc liquid or a certain compound labeled with 99mTc, enter the human body through oral, aerosol inhalation, intravenous injection and other channels, targeted to reach…

Discharge tungsten needle is made of high-quality tungsten alloy (W>98%) or pure tungsten (W>99.95%), which has advantages of stable discharge, high hardness, high heat resistance, high temperature resistance, safety and rapid welding effect. And it is not easy to deform. More details, please visit: http://tungsten.com.cn/tungsten-needles.html Discharge tungsten needle is used to replace traditional stainless steel needle because of its superior performance, durability, and extraordinary discharge effect. The discharge part of discharge tungsten needle is concentrated, and the needle tip can…

Ion fan tungsten needle refers to the tungsten needle used for an ion fan. Wherein, the ion fan has excellent anti-static performance, can prevent static electricity pollution, and is small, light, and easy to install. It is an ideal equipment for personal static protection areas such as electronic production lines and maintenance stations. More details, please visit: http://tungsten.com.cn/tungsten-needles.html As the core component of the ion fan, the discharge needle is usually a tungsten needle or a stainless steel needle. Although…
