Patient-specific quality assurance of dynamically-collimated proton therapy treatment plans. [PDF]

Med Phys
AbstractBackgroundThe dynamic collimation system (DCS) provides energy layer‐specific collimation for pencil beam scanning (PBS) proton therapy using two pairs of orthogonal nickel trimmer blades. While excellent measurement‐to‐calculation agreement has been demonstrated for simple cube‐shaped DCS‐trimmed dose distributions, no comparison of ...

Feasibility study of structural similarity index for patient-specific quality assurance. [PDF]

J Appl Clin Med Phys
AbstractBackgroundThe traditional gamma evaluation method combines dose difference (DD) and distance‐to‐agreement (DTA) to assess the agreement between two dose distributions. However, while gamma evaluation can identify the location of errors, it does not provide information about the type of errors.PurposeThe purpose of this study is to optimize and ...
