Recall details

Recalling firm

Philips Healthcare Inc.

Reason for recall

Philips Healthcare discovered the customer was performing CTDI measurements for facility accreditation and received results that were 15 to 25% higher than Philips protocol parameters stated.

Action taken

Philips Healthcare proposed corrective action plan (CAP) is comprised of the following elements: * Updating procedures in manufacturing to verify, either through software calibration or through gage-pin measurement, that A-plane collimation is appropriate to the design specification. It is our understanding that these procedures have been implemented. * For refurbished PET/CT and SPECT/CT systems distributed by Philips, the manufacturing process now requires that CTDI testing be conducted in addition to air testing and that each system meet updated CTDI tolerance limits to be published in the product's instructions for use. * Reassessing and correcting the correlation between air dose and CTDI specifications for all CT systems or sub-systems, resulting in updates of the CTDI specifications (tolerances) to be published in the instructions for use. It is our understanding that this reassessment and correction have been implemented, that the updated CTDI specifications will be made available as new CTDI tolerance tables with the customer information letter to be distributed immediately, and that these updated CTDI specifications will also be distributed as an addendum to the instructions for use manuals to the installed base during the next 12 months. * For all Brilliance CT, Gemini PET/CT, and Precedence SPECT/CT systems, in the installed base as well as in forward production, instructions for field service will be updated to provide clear directions on how to verify that the A-plane collimator has been appropriately adjusted to ensure expected product performance after its replacement and/or the replacement of an x-ray tube. This plan appears to adequately address the problem, and it is hereby approved. For further questions please call (978) 687-1501.
