NOTES

1) A justification of SAR compliance must be provided for all coils intended for Human use. Submit SAR estimates to the CAMRIS committee for approval.

2) Tests 3 and 4 determine the maximum RF power level for which a coil will be approved for animal or human exams.

3) The completed test results forms are to be kept by the PI and a copy placed on file in the RF lab.

4) An individual designated by the RF lab staff is to be present for Test 4 and will assist with tests 1- 3 upon request.

5) Test 4 will be performed for the purpose of approving the coil for either routine use or further development involving human subjects. For routine use, the coil must be physically robust, having a permanent covering of thickness equal to half the distance between distributed capacitors. The PI may provide CAMRIS with scientific evidence that it is safe to use padding of less thickness than half the spacing.

Only routine-use coils may be used on people not specified as approved volunteers.

An important issue is who is responsible for performing the 4 tests described in the RF TEST MANUAL and for verifying that these tests were performed correctly. The coil builder may be approved to perform Tests #1-3.

Test 4, the human subject test, described in the RF TEST MANUAL must be performed in the presence of a person who has been specifically designated by the CAMRIS Committee to oversee Test 4 performed. The CAMRIS Committee must be confident that the person performing these tests is capable and reliable. Thus, it is left up to the committee's discretion as to the capability of the coil builder to perform the tests to their satisfaction.
