Abstract
With the aid of an X-ray CT (), the spatial position (r) of a body cavity that is filled with blood is determined, which for example can be a part of the aorta or of the left ventricle of the heart of a patient (). Subsequently, a TOF-PET unit that includes two detector elements () is positioned to place a predefined volume element () in the blood filled body cavity. From pairs of annihilation quanta received from the volume element () a concentration of the tracer in this volume element () and thus in the blood is determined. This concentration can for example be used within the framework of pharmaco-kinetic examinations which are carried out on the patient () with the aid of a three-dimensional PET unit ().
