The nuclear medicine division of Siemens Medical Systems in Hoffman Estates, IL, has received 510(k) clearance for its Profile attenuation correction device for the E.Cam variable-angle dual-head gamma camera. Profile uses a multiple-line array of radioactive sources, in which a series of stationary line sources are placed along an arc and positioned in such a way that the sources appear as a single-sheet source. This eliminates the complexity associated with scanning line sources, and avoids the cost, weight, and shielding requirements found in sheet sources, according to Siemens.
