Penumbra TAR/TMF PDD BSF

  1. BSF is equal to ______ at Dmax.
    TAR
  2. PDD is directly proportional to:
    • Field Size
    • Energy
    • Distance (SSD)

    (PDD needs the FED)
  3. PDD is inversely proportional to:
    Depth

    (both PDD & TMR are inversely proportional to depth)
  4. TAR & TMR are directly proportional to:
    Field Size & Energy (aka beam quality)

    (TMR = FE)
  5. TAR & TMR are inversely proprtional to:
    Depth

    (both PDD & TMR are inversely proportional to depth)
  6. TAR & TMR are independent of:
    SSD

    (that's why it's perfect for SAD tx's)
  7. BSF or PSF is dependent on:
    Field Size & Energy
  8. Penumbra is directly proportional to:
    • SSD
    • Source Size
  9. Penumbra is indirectly proportional to:
    SCD
  10. TAR = TMR X _____
    BSF

    TAR = TMR X BSF
