Description
・実際の金銭的コスト、
・機器の利用可能性、
・対応できる人員の作業負荷、又は
・治療を受けない他の患者への不利益。
式中、f(dSMLC,dVMAT)は、SMLC放射線セットの線量分配dSMLC及びVMAT放射線セットの線量分配dVMATに関連する目的関数であり、tSMLC及びtVMATは、それぞれSMLC放射線セット及びVMAT放射線セットの送達時間である。目的関数は、例えば、放射線セットの個々の線量をスコアリングするか、又は放射線セットの合計線量をスコアリングするか、又はこれらの組み合わせをスコアリングすることができ、すなわち、いくつかの目的関数構成関数f1、f2、及びf3について、
式中、
は、臓器に対する光子の最大許容フラクション線量である。すなわち、放射線感受性の高い臓器のボクセルのセットOAR内の各ボクセルiについて、合計線量が最大許容フラクション線量×フラクションの数よりも大きい場合に、二次ペナルティが存在する。
