Author-Highlights•The feasibility of a pinhole camera system for online dosimetry in BNCT was studied.•A prototype pinhole camera system for online dose imaging for BNCT was built.•Prompt γ-rays from a phantom irradiated with neutrons were detected.•The boron-10 reaction rate distribution was reconstructed from the experimental data.

The feasibility of a pinhole camera system for online dosimetry in boron neutron capture therapy (BNCT) was studied. A prototype system was designed and built. Prompt γ-rays from the 10B(n,α)7Li reaction from a phantom irradiated with neutrons were detected with the prototype system. An image was reconstructed from the experimental data. The reconstructed image showed a good separation of the two borated regions in the phantom. The counting rates and signal-to-noise ratio when using the system in actual BNCT applications are also discussed.
