      The treatment machine central axis (CAX) was placed at the level of the L4-L5 vertebral body interspace.
    • 2000, Kung et al.: A monitor unit verification calculation in intensity modulated radiotherapy as a dosimetry quality assurance, page 1:
      For dose calculation along a central axis (CAX), we first replace the incident IMRT fluence by an azimuthally averaged fluence.
    • 1999, Vincent et al.: An assessment of the number of CT slices necessary to plan breast radiotherapy, page 1:
      A separate optimized plan was generated using the CAX slice and two slices indicative of the upper and lower level of the field.
    • 1997, Lee: Monte Carlo simulations of the differential beam hardening effect of a flattening filter on a therapeutic x-ray beam, page 1:
      Compared to the unfiltered beam, the fluence-weighted photon energy of the filtered beam increases to 1.93 MeV at CAX and to 1.36 MeV at an OAD of 20.0 cm, respectively.
