Product | SEQUENCER component of MOSAIQ versions 1.30 (all builds), 1.40 (all builds), 1.50 (all builds), 1.60 (all builds), and 2.0 (all builds). Manufactured by IMPAC Medical Systems, Inc. Sunnyvale, CA.
The intended use of SEQUENCER (a verification system) is to assist in the process of patient treatment on a radiotherapy treatment machine. SEQUENCER provides the capability to notify the users of actions that need to take place prior to treatment, to display reference images for set up purposes, and to auto setup the machine to predefined settings. Actual settings are read from the treatment machine, via the machine's communication interface, and compared to the predefined values. If a mismatch occurs between the planned values and the actual machine settings, treatment is prohibited. At appropriate times during the treatment, the actual delivered values are recorded to provide treatment tracking. Treatments are initiated by the operator, via the machine control system, only after the user has verified that the treatment setup is correct. SEQUENCER does not bypass any checks put in place by the machine's control system. |
