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.

It has been reported that using tungsten alloy multileaf collimator in radiotherapy can effectively improve the accuracy of radiotherapy, thereby improving patients' quality of life, reducing the labor intensity of workers, and improving their work efficiency. Throughout its historical development, tungsten alloy multileaf collimators are mainly developed around advanced features such as improving conformity, reducing transmission penumbra and leakage, and adapting to dynamic and dynamic wedge plates. For example, the number of pairs of tungsten alloy leaves varies from small to large, and the width of the leaves varies from thick to thin.
