ExacTrac is intended to be used to place patients at an accurately defined point within the treatment beam of a medical accelerator for stereotactic radiosurgery or radiotherapy procedures, in order to treat lesions, tumors and conditions anywhere in the body when radiation treatment is indicated. ExacTrac may also be used to monitor the patient position during the treatment.

Reason: When using multiple isocenters (radiation treatment targets) within a single plan, in certain workflow conditions ExacTrac v.6.0.4 might move the patient to an unintended isocenter position, despite displaying the green "OK" icon. If this anomaly occurs and is not detected by the user, the radiation treatment dose at the linear accelerator may be delivered to the unintended target position.
