SYSTEM AND METHOD FOR SENSITIVITY-BASED PATIENT POSITIONING FOR EMISSION TOMOGRAPHY IMAGING

Abstract

An example imaging system includes a detector array arranged in multiple rings defining an axial field of view (AFOV), a patient table configured to translate a subject along the AFOV, wherein the detector array includes one or more detector modules to acquire emission tomography scan data at a first bed position and at a second bed position, and one or more processors to combine scan data from overlapping scan ranges of the first and second bed positions to generate a combined sensitivity profile across a desired scan range and to reconstruct a diagnostic image using the combined data, wherein the combined sensitivity profile exhibits increased sensitivity in a central section of the overlap relative to sensitivity obtained from a single bed position.
