    How do you calculate ODI distance in Linac & mg?
    The SMD is initially established for each LINAC and MG by the user with the help of SSD calibration rods, which are routinely supplied by the accelerator manufacturer. Subsequential verification of ODI distance is performed by measuring the MSD and applying the relation SSD = MSD + SMD.

    How does ODI work?
    ODI is a device which shows the SSD on the surface using an optical graded ruler. In other words, ODI shows the current SSD by projecting the number on the couch. Currently a mechanical distance indicator is used to verify the ODI [ 5 ]. Welsh et al. [ 2] used a tape measure with a digital screen to show the SSD for the ODI verification.

    What is ODI QC test?
    The ODI QC test has been performed on an ELEKTA Precise and a SIEMENS Primus LINACs. The measurements for ODI QC test were made at 95, 105, 110 and 115 cm for the SSD and in all the heights the gantry angle was at the zero degree.

    What does ODI score mean?
    For example, scoring participants considered how often the optical distance indicator (ODI) test has fallen out of tolerance in their experience. Scoring participants assigned a severity score to each performance test.
