Fig. 12From: Feasibility study of a SiPM-fiber detector for non-invasive measurement of arterial input function for preclinical and clinical positron emission tomographySensitivity of the fiber detector as a function of the lower energy threshold for simulations and measurements performed with a water filled tube containing 18F (a) and 68Ga (b). The blue line refers to the simulated sensitivity as a function of the lower energy threshold and the orange dot to the experimentally measured sensitivity with an estimated lower energy threshold of about 100 keVBack to article page
