Accurate liver tumor delineation is crucial for radiation therapy, but liver tumor volumes are difficult to visualize with conventional single‐energy CT. This work investigates the use of split‐filter dual‐energy CT (DECT) for liver tumor visibility by quantifying contrast and contrast‐to‐noise ratio (CNR).

研究分裂过滤器双能CT可以改善放射治疗的肝肿瘤可见度。

准确的肝肿瘤轮廓对放射治疗至关重要，但是传统的单能CT很难显示肝肿瘤的体积。这项工作通过量化对比和对比噪声比（CNR），研究了使用裂隙双能量CT（DECT）改善肝脏肿瘤的可见性。
