Evaluation of a CdTe semiconductor‐based gamma camera for real‐time dose dosimetry in boron neutron capture therapy
This study demonstrates that a CdTe-DSD-based gamma camera is a promising tool for real-time boron dosimetry in BNCT. The detector's high energy resolution and excellent spatial resolution enable precise detection of 478 keV prompt <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:semantics><mml:mi>γ</mml:mi> <mml:annotation>$\gamma$</mml:annotation></mml:semantics> </mml:math> -rays, facilitating accurate mapping of boron distribution during neutron irradiation. These findings support the developed system's potential to enhance BNCT treatment planning and patient-specific dose monitoring. Future research will optimize neutron shielding and explore advanced collimator designs to improve sensitivity in clinical settings.
