[0002] During radiotherapy, the normal operation of the radiotherapy equipment and the fact that the radiation dose remains within the normal range have a significant impact on the treatment process. Therefore, dynamic monitoring of the status of the radiotherapy equipment and the radiation dose is crucial during radiotherapy.
[0003] Traditional radiotherapy room monitoring devices typically use a single radiation sensor paired with a software control platform. Their functionality is relatively limited; the sensor only monitors radiation dose and does not integrate monitoring of parameters such as equipment temperature and mechanical position, making it difficult to comprehensively reflect the equipment's operating status. Furthermore, the alarm logic for abnormal situations needs to be implemented through software algorithms, resulting in response delays (typically >100ms) and potential technical issues such as alarm failure due to program freezes or crashes. Additionally, existing alarm systems lack intuitive dynamic displays and alarm functions, hindering operators from judging and responding to doses at different locations and times.
