이것은 무엇인가요?

안전성 경고는 의료기기 제품과 관련된 중요한 정보와 권고사항을 담고 있습니다. 물론 안전성 경고가 배포되었다고 해서 해당 제품이 무조건 안전하지 않은 제품이라는 것은 아닙니다. 보건의료업계 종사자와 의료기기 사용자들에게 배포되는 안전성 경고에는 회수(recall)도 포함될 수 있습니다. 제조사가 안전성 경고를 작성하기도 하지만, 보건당국에서 작성하는 경우도 있습니다.

    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.

    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. ".
