Description
Summary:Highlights • Bremsstrahlung production of β-emitting isotopes was investigated using Monte-Carlo. • The simulated and measured spectra detected by SPECT camera were studied. • Simulated and measured spectra showed good agreement. • Bremsstrahlung contributions to the photopeak for Lu-177 and Re-188 are negligible. • A wide energy window with high energy collimator is recommended for Y-90 imaging.
