Simulated energy spectra of detected events (a) and detection efficiency as a function of the lower energy threshold (b) for simulations of the human wrist and a single cylindrical fiber detector including results for 18F (blue) and 68Ga (orange) placed in an artery at 2 mm depth. Only a few positrons from 18F were detected resulting in negligible counts and efficiency as depicted with blue lines
