- •
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.
