Philips Medical Systems North America of Shelton, CT, is recalling two of its CT scanners, Tomoscan SR4000 and Tomoscan M/EG. With Tomoscan SR4000, a defect is occurring when the image is reversed in the unit’s data bank. This causes the image to be reversed left to right upon retrieval, according to Food and Drug Administration documents. Fifteen of these scanners were distributed.
A version of the Tomoscan M/EG scanner, manufactured for Philips by Peabody, MA-based Analogic, is not interrupting the exposure when the tabletop movement stops during volume-scan mode. This can result in the patient receiving excess exposure at a particular scan plane, according to the documents. Forty-four of these units were distributed. Field correction is underway for both Tomoscan systems.
