Bone models for use in radiotherapy dosimetry

H Q Woodard, D R White

    The British Journal of Radiology
    |April 1, 1982

    Summary
    This summary is machine-generated.

    Developing realistic artificial bone phantoms for radiotherapy dosimetry is difficult due to missing elemental data. This study provides crucial elemental composition data for human bones, enabling the creation of better bone substitute materials for accurate radiation treatment planning.
