Title:
POSITION DETECTION DEVICES OF MULTI-LEAF COLLIMATORS
Document Type and Number:
WIPO Patent Application WO/2024/027741
Kind Code:
A1
Abstract:
A position detection device of a multi-leaf collimator (MLC) is provided. The position detection device includes a signal emitting component, a signal feedback component, and a processor. The signal emitting component is configured to emit a signal. The signal feedback component is configured to receive the signal emitted by the signal emitting component and generate a feedback signal in response to the received signal. Installation positions of the signal emitting component and the signal feedback component are arranged so that the signal emitted by the signal emitting component can be projected onto the signal feedback component. The processor communicatively connected with the signal feedback component and configured to receive the feedback signal from the signal feedback component and determine a moving stroke of a leaf of the MLC based on the feedback signal.
