English(EN) Deformable CT-US Registration via Anatomy-Aware Implicit Neural Representations

新框架通过解剖先验改进 CT-US 图像配准

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-07 04:00

研究人员开发了一种新的框架，用于超声 (US) 和计算机断层扫描 (CT) 成像之间的可变形配准。该方法结合了来自 CT 的解剖先验以改进对齐，特别是在软组织在手术过程中发生变形的情况下。该系统使用正弦隐式神经表示 (SIREN) 来估计可变形变换，并从基于 CT 的 HU 值近似组织刚度以指导变形过程。额外的约束捕捉了探头接触和光束几何的物理特性，从而在刚性初始化和经典可变形方法之上实现了改进的对齐。 AI

影响这项研究通过改进不同成像模式的对齐，有可能提高医疗干预的精度。
