What is this?

Alerts provide important information and recommendations about products. Even though an alert has been issued, it does not necessarily mean a product is considered to be unsafe. Safety Alerts, addressed to health workers and users, may include recalls. They can be written by manufacturers, but also by health officials.

    Brazilian data is current through June 2018. All of the data comes from Anvisa, except for the categories Manufacturer Parent Company and Product Classification.
    The Parent Company and the Product Classification were added by ICIJ.
    The parent company information is based on 2017 public records. The device classification information comes from FDA’s Product Classification by Review Panel, based on matches of data from the U.S. and Brazil.
  • Extra notes in the data
    The company recommends that the user be aware of the following guidelines: "As often required, always ensure that the correct DRRs of the current patient are displayed in ExacTrac and that a precise fusion with the X-ray images for patient placement is possible. If incorrect DRRs are displayed, quit and restart the ExacTrac software. To minimize the likelihood of this problem occurring in the affected ExacTrac versions: - Reduce to the maximum the number of contours exported to ExacTrac (export to ExacTrac only the contours required for positioning). - Avoid exporting large contours to the ExacTrac, such as table top models. -After each (re) initialization of the ExacTrac application on any workstation, always load first a phantom plane that does not contain outlines. Generate DRRs from that phantom once by selecting the Define DRR Settings tab before loading other patient treatment plans. General reminder: Continue to follow the instructions and warnings described in the User's Guide. In the context of this notification, specifically take into account the relevant safety observations for X-ray correction and verification: - Image overlay functions should be used to verify the accuracy of the fusion in both image views, especially if the images contain a series of similar structures such as the vertebrae. - Do not perform patient treatment unless accurate imaging is possible. - Large correction displacements (eg, greater than 10 mm) may indicate an incorrect automatic melting. In these cases, check the offset offset a second time. - Image overlay functions should be used to verify the accuracy of the fusion in both image views, especially if the images contain a series of similar structures such as the vertebrae. - Do not perform patient treatment unless accurate imaging is possible. - Large correction displacements (eg, greater than 10 mm) may indicate an incorrect automatic melting. In these cases, check the offset offset a second time. "
  • Reason
    According to the company, "a user in the united states has detected that exactrac exhibited the digitally reconstructed radiograph (drr) of the previously uploaded patient data sequence, rather than the correct drr in a later open patient treatment plan. the exactrac application resulting in the correct ddr display. " the company notes that "applying an incorrect displacement can result in a target position of the treatment and the patient in the linear accelerator (linac) different from the intended position. as a consequence, the treatment dose may be applied in a region other than the desired target region. if the deviation exceeds clinically acceptable limits, this may result in ineffective treatment, serious injury to the patient. ".
  • Action
    Company will send the safety notice (APPENDIX) to the customers and will perform the software revision (ExacTrac v. 6.0.6) with the solution to this problem Field Correction / Software Update - CAPA-20150713-001446.
