Title: (EN) PRE-OPTIMIZATION METHOD FOR QUICK PREDICTION OF ACHIEVABILITY OF CLINICAL GOALS IN INTENSITY MODULATED RADIATION THERAPY
(ZH) 强度调制辐射治疗中临床目标的可实现性的快速预测的预优化方法
Abstract: front page image
(EN) An achievability estimate is computed for an intensity modulated radiation therapy (IMRT) geometry (32) including a target volume, an organ at risk (OAR), and at least one radiation beam. Namely, a geometric complexity (GC) metric is computed for the IMRT geometry that compares a number NT of beamlets of the at least one radiation beam available in the IMRT geometry for irradiating the target volume and a number n of these beamlets that also pass through the OAR. A GC metric ratio is computed of the GC metric for the IMRT geometry and the GC metric for a reference IMRT geometry for which an IMRT plan is achievable. If the clinician is satisfied with this estimate then optimization (38) of an IMRT plan for the IMRT geometry (32) is performed. Alternatively, a reference IMRT geometry is selected by comparing the GC metric with GC metrics of past IMRT plans.
(ZH) 计算针对强度调制放射治疗(IMRT)几何配置(32)的可实现性估计,所述几何配置包括目标体积、风险器官(OAR)和至少一个辐射束。即,计算针对IMRT几何配置的几何复杂度(GC)度量,其将IMRT几何配置中所述至少一个辐射束中的用于辐照所述目标体积的子射束的数量NT与这些子射束中也穿过所述OAR的数量n进行比较。计算针对IMRT几何配置的GC度量与针对IMRT计划可实现的参考IMRT几何配置的GC度量的GC度量比率。如果临床医师对该估计满意,则执行针对IMRT几何配置(32)的IMRT计划的优化(38)。替代地,通过将GC度量与过去IMRT计划的GC度量进行比较来选择参考IMRT几何配置。
