Abstract
An apparatus and method for a PET/MR system having a PET scanner and an MR scanner. A patient may be advanced through the system in sequential stations, with multiple transverse slices defined within at least one of the stations in which each slice is offset a distance Δz from the station centerline. The method may comprise the steps of: defining a center and an annulus thereabout for each slice, wherein the annulus has an inner radius Rand an outer radius R; conducting attenuation correction of the PET images using only MR data from the region within the inner radius, only PET data from the region outside the outer radius, and a combination of PET and MR data from the region of the annulus; and varying Ras a function of Δz for selected slices within the station.
