Calibration of ionization chambers in air kerma length [PDF]
Physics in Medicine and Biology, 2001 Pencil ionization chambers are employed for the direct determination of the computed tomography dose index (CTDI), which is used for patient dosimetry in CT examinations. The chambers are calibrated in air kerma length in a reference x-ray field. The precision of calibration is influenced by several factors which are investigated in the present work ...
