摘要：
Provided is a multi-leaf collimator, belonging to the field of medical instruments and comprising: two leaf sets and a drive device (12), arranged opposite to each other； each leaf set comprises a plurality of leaves (1)； each leaf (1) is connected to the drive device (12)； the leaf (1) may move bidirectionally driven by the drive device (12)； also comprised are a U-shaped optoelectronic switch system (A11) and a signal processing device (A20), said U-shaped optoelectronic switch system (A11) comprising: a plurality of U-shaped optoelectronic switches (4), corresponding to each leaf (1), arranged according to the direction of motion of the leaf (1)； the U-shaped optoelectronic switch (4) is arranged on the upper end face side or lower end face side of the leaf (1)； the U-shaped optoelectronic switch (4) comprises a U-shaped groove and a transmitter and receiver located at the two sides of the U-shaped groove； the leaf (1) is arranged inside the U-shaped groove and moves inside the U-shaped groove； the U-shaped optoelectronic switch system (A11) is connected to the signal processing system (A20), and the signal processing system (A20) is used for processing a pulse signal outputted by the U-shaped optoelectronic switch system (A11) in order to obtain a quantification value of the state of motion of the leaf (1). The multi-leaf collimator has improved reliability of monitoring and control of the leaves (1).L'invention concerne un collimateur multilames, appartenant au domaine des instruments médicaux et comprenant : deux ensembles de lames et un dispositif d'entraînement (12), disposés à l'opposé l'un de l'autre； chaque ensemble de lames comprend une pluralité de lames (1)； chaque lame (1) est reliée au dispositif d'entraînement (12)； la lame (1) peut se déplacer de manière bidirectionnelle entraînée par le dispositif d'entraînement (12)； un système de commutation optoélectronique en forme de U (A11) et un dispositif de traitement de signal (A20) sont également compri
