Defective yellow tungsten oxide nanoparticle can be used to convert solar energy into thermal energy, thereby developing a new type of photothermal conversion material.

Yellow tungsten oxide, or tungsten trioxide (WO3), may be widely applied for producing photocatalytic coating. Tungsten trioxide has band gap between 2.4-28eV, and has good absorption of visible light. Also, it is very stable in aqueous solution. So, it is regarded as a potential photocatalytic material for visible light response. Therefore, WO3 photocatalyst with excellent visible light photocatalytic performance may be used to produce photocatalytic coating.

Tungsten alloy collimator is used in an anger camera for collimation and absorption of gamma rays. And therefore, it improves imaging quality and protects patients. Anger camera, which is more often known as gamma camera or γ-camera, is a device used to image gamma radiation emitting radioisotopes.

Tungsten alloy X-ray collimator is a highprecision collimator for X-ray detectors, which absorbs scattered radiation and thus helps ensure an extremely high image quality. W (tungsten alloy) is better suited for this task than any other element in the periodic table as it has high density and excellent X-ray absorption capability.

Tungsten alloy collimator is an important part in a CT scanner for CT testing. It is reported that researchers have developed a new type of tungsten alloy collimator for CT testing. Such a collimator can be adjusted manually, and the operation is simple and practical. Also, the cost is low. More importantly, it effectively solves the problem of high precision and many other strict requirements of a collimator. While ensuring the imaging quality of a CT scanner, it also brings convenience to the processing of collimators.

CT scanner tungsten alloy collimator, as its name suggests, is tungsten alloy collimator used in the CT scanner. There are two tungsten alloy collimators on a CT scanner. And they are known as pre-patient collimator and post-patient collimator, respectively.

Tungsten alloy collimator is an important part of X-ray CT scanner in a PET-CT scanner, which can achieve both functions of collimation and radiation shielding. Wherein, PET-CT is a nuclear medicine technique which combines a positron emission tomography (PET) scanner and an X-ray CT scanner to acquire sequential images from both devices in the same session, which are combined into a single superposed image.

Tungsten alloy collimator is applied for SPECT-CT scanner to replace lead collimator to guide X-rays. Also, such a high density collimator shields gamma rays and X-rays to provide radiation protection for patients and accompanying personnel as the radioactive isotope used for SPECT-CT is technetium 99.

SPECT tungsten alloy collimator is a new type of lead-free collimator, and is made of high quality tungsten-based alloy - a new type of environmentally friendly shielding material with good absorption properties for gamma rays (due to its own high density). It means that tungsten alloy collimator is used in nuclear medicine imaging. But do you know why SPECT is also known as gamma camera?

Tungsten alloy collimator is the core component of a γ camera (gamma camera), more specifically, it is an important part of the detector on a gamma camera. Gamma rays from radioactive source within the body emitted in all directions, so a collimator is needed to achieve high degree of collimation.
