| Classification | Class II |
| Status | Terminated |
| Reason | Signature from the user is necessary to proceed with specific actions in the Proton Therapy System (PTS). IBA became aware that the PTS does not accept user names with more than ten characters. It is an issue when the user has no other choice than resuming an aborted treatment field based on the overall delivered dose displayed on the Dose Counter Electronic Unit (DCEU). User s signature is required to perform this action. If the signature contains more than ten characters, the user will not be able to complete the aborted treatment field. An additional issue applies to Electronic Medical Record (EMR) centric sites and may increase the probability of not being able to complete an aborted treatment field. It is not possible, in a new session, to resume from a local partial archive if the Patient Positioning System (PPS) position has changed. If the user captures the PPS position at every session in the Oncology Information System (OIS) just after the setup process, the prescribed PPS position is changed for the next session in the OIS. This includes the partial continuation session. Therefore, when comparing the prescribed PPS position between OIS and local database, the PTS sees a difference and rejects the local partial archive. This problem forces the user to resume the interrupted irradiation based on the overall delivered dose displayed on the DCEU instead of resuming from the full details of the interrupted beam. |
