One-dimensional WO2.72 nanowire is also known as one-dimensional W18O49 nanowire, which can be synthesized by a simple, template-free solvothermal method. Wherein, WO2.72 and W18O49 are the formulas of violet tungsten oxide. Studies have shown that one-dimensional WO2.72 nanowires can be used as counter electrode materials for dye-sensitized solar cells. Compared with the three-dimensional multi-level structure, one-dimensional WO2.72 nanowire counter electrode has two prominent features: More details, please visit: http://tungsten-oxide.com/index.html 1. Nanowires grow highly preferentially along the [010] crystal direction, which…

Tungsten alloy shield for dynamic multi-leaf collimator is tungsten alloy leaf on dynamic multi-leaf collimator. Certainly, there are multiple leaves. Dynamic multi-leaf collimator of linear accelerator was firstly used to replace conventional low melting alloy blocks, and was extensively used in clinical practice for the radiotherapy of different tumors. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html More specially, the dynamic multi-leaf collimator with tungsten alloy shield is now available as an integral or optional retrofit component of linear accelerator heads, permitting to…

Tungsten alloy leaf has high atomic coefficient and high density so that it has a strong ability to shield rays in a multi-leaf collimator. It has been reported that multi-leaf collimator with tungsten alloy leaf improves both the accuracy and the effectiveness of radiation therapy and reduces the time for every treatment dose, which potentially increases the number of patients treated every day. The multileaf collimator is presently an important technical tool either to replace conventional shielding for static conformational…

What is the working principle of tungsten alloy multi-leaf collimator? Let’s begin with some pieces of information of multi-leaf collimator. Tungsten alloy multi-leaf collimator, which was developed to replace the traditional lead blocks, are used on linear accelerators to provide conformal shaping of radiotherapy treatment beams. And specifically, conformal radiotherapy and intensity modulated radiation therapy can be delivered using multi-leaf collimators. The multi-leaf collimator has movable tungsten alloy leaves to block some fraction of the radiation beam. Typically, multi-leaf collimators…

A tungsten alloy multi-leaf collimator has been in routine clinical use for both conventional and conformal radiotherapy for many years. And there are many pieces of medical shields in tungsten alloy multi-leaf collimator. They are tungsten alloy leaves. According to a report, the collimator comprised of 80 tungsten alloy leaves and two orthogonal pairs of back-up collimators is used to replace the conventional treatment head of a linear accelerator. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html It has been reported that each…

It has been reported that the electron linear accelerator equipped with a tungsten alloy multileaf collimator can make the irradiation field as close as possible to the shape of the tumor, and achieve the purpose of killing the tumor cells to the greatest extent and affecting the normal tissue to the least extent. Generally, tungsten alloy multileaf collimators have unique designs for applying to different electron linear accelerators. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html Tungsten alloy multileaf collimator is an important…

Tungsten alloy multileaf collimator firstly used tungsten alloy leaves to shape structures in 1965 and has improved rapidly to modern day operation in radiotherapy. Tungsten alloy multileaf collimators are now widely used and have become an integral part of any radiotherapy department as they have strong shielding performance against rays while ensuring high accuracy. A pair of tungsten alloy leaves can form a rectangular irradiation field, and multiple pairs of tungsten alloy leaves can be combined to form an irradiation…

Tungsten alloy multileaf collimator is a collimator or beam-limiting device that is made of some individual leaves of tungsten alloy material. Each tungsten alloy leaf is connected by a screw rod and a drive motor to form an irregular field under the control of computer software. And these tungsten alloy leaves can move independently in and out of the path of a radiotherapy beam in order to shape it and vary its intensity. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html It has…

Tungsten alloy shield is a very important part in multileaf collimator – a device commonly used in radiation medicine. Tungsten alloy shields are some tungsten alloy leaves having good X-ray shielding properties on the multileaf collimator. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html It is reported that the multileaf collimator appeared in 1990 is used to replace the traditional lead block, so that it can effectively improve the accuracy of radiotherapy to reduce the treatment time of patients and the workload of…
