AI Technical Summary
Existing multi-leaf collimators face challenges in accurately detecting and controlling the position of thin plates due to markers peeling off, especially with thin leaves, leading to erroneous position detection and reduced adhesion, which is exacerbated by the use of fluorescent paint or markers with small widths.
Integrating phosphor-containing plates into the leaves and fixing them to the end surfaces as markers, allowing for accurate detection and control of leaf positions through image processing, enhancing adhesion and reducing peeling.
The solution ensures accurate detection and control of leaf positions, improving marker recognition and reducing peeling, thereby enhancing the precision of radiation delivery in radiotherapy devices.
