POSITION SENSORING METHOD AND SYSTEM FOR A MULTI-LEAF COLLIMATOR |
摘要 |
A multi-leaf collimator for radiation therapy in which the position of the leaves are determined by measuring a magnetic field allows to determine the leaf position with enhanced precision, and is at the same time robust to perturbations or disturbances. The magnetic sensor may comprise a magnetic encoder that varies in a predefined pattern along a lengthwise direction of the magnetic element, in particular according to a step function. |
