Investigating the use of ionization chamber and solid‐state detectors to evaluate kerma‐area product meter accuracy under TG‐125 geometry across variable field of views

The results indicated that the <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:semantics> <mml:msub><mml:mover><mml:mi>K</mml:mi> <mml:mo>̇</mml:mo></mml:mover> <mml:mrow><mml:mi>a</mml:mi> <mml:mo>,</mml:mo> <mml:mi>r</mml:mi></mml:mrow> </mml:msub> <mml:annotation>${\dot{K} _{a,r}}$</mml:annotation></mml:semantics> </mml:math> values of KAP meter were increased with the FOV. Furthermore, the SSDs could be utilized to evaluate the KAP meter accuracy in TG-125 geometry.
