English(EN) PAGS: Autofocusing Photoacoustic Tomography via Speed-of-Sound-Adaptive Gaussian Splatting

新的PAGS框架通过速度自适应改进光声断层成像

作者 PulseAugur 编辑部 · [1 个来源] · 2026-08-27 04:00

研究人员开发了PAGS，一种用于光声计算机断层成像（PACT）的新型框架，解决了未知声速异质性的挑战。该方法使用声速自适应高斯泼溅实现盲自动对焦，用稀疏高斯光声源表示初始压力场。PAGS直接从测量数据更新源参数和声速场，无需校准的声速先验，并展示了重建清晰度和计算效率的提高。 AI

影响引入了一种新颖的医学成像计算框架，有望提高诊断准确性和效率。

PAGS：通过声速自适应高斯泼溅实现自动对焦光声断层扫描

arXiv:2608.25472v1 Announce Type: new Abstract: Photoacoustic computed tomography (PACT) combines optical absorption contrast with acoustic detection for high-resolution deep-tissue imaging. A persistent challenge is that unknown speed-of-sound (SoS) heterogeneity changes acousti…
