Biomedical photoacoustic tomography, which can provide high-resolution 3D soft tissue
images based on optical absorption, has advanced to the stage at which translation from the …

Two common issues of least-squares reverse time migration (LSRTM) consist of the many
iterations required to produce substantial subsurface imaging improvements and the …

Model-based learned iterative reconstruction methods have recently been shown to
outperform classical reconstruction algorithms. Applicability of these methods to large scale …

In photoacoustic tomography (PAT) with a flat sensor, we routinely encounter two types of
limited data. The first is due to using a finite sensor and is especially perceptible if the region …

光声成像(Photoacoustic imaging, PAI) 是一种多物理场耦合的新型功能成像技术,
高质量图像重建是提高成像精度的关键. 当探测器采集的光声信号数据不完备时 …

Curvelet frame is of special significance for photoacoustic tomography (PAT) due to its
sparsifying and microlocalisation properties. In this PhD project, we explore the methods for …
