Abstract

收起

The high-precision collimator is the core component of a medical linear accelerator (linac) for delivering precise radiotherapy, and its performance directly impacts treatment precision. As the requirements for treatment precision continue to increase, the collimator design in high-performance linac products has been continuously iterated and innovated. The development of novel collimators has become a key link in radiotherapy product innovation. This article introduces several types of collimators widely used in medical linacs on the market, analyzes and compares the performance and structural characteristics of different collimators, summarizes the key technical points in collimator design and manufacturing, and provides an outlook on the development of collimators for medical linac products. This holds significant reference value for the research and development of domestically produced medical linear accelerators.

Key words
