Matrix-free photoacoustic image reconstruction via sensor-token networks

Photoacoustic tomography (PAT) couples optical absorption contrast with ultrasound resolution, but reconstructing the initial pressure distribution from sparse-view measurements is an ill-posed inverse problem. Iterative compressive-sensing solvers and unrolled deep networks both retain a dependence on the system m...

Measuring Curriculum Alignment across Topical Coverage, Competency, and Cognitive Depth: A Longitudinal Framework Applied to CS2013 and CS2023

The program articulates most competencies it covers yet meets the recommended cognitive depth far less often under CS2023 than under CS2013, a gap that survives a sensitivity analysis of the mapping, while structural gaps stay separable from artifacts of the standard's evolution.

Matrix-Free Photoacoustic Image Reconstruction via Sensor-Token Self-Attention

The Sensor Attention Network is proposed, a Transformer-based architecture that treats the full time series of each sensor as a token and maps raw measurements directly to the reconstructed image without invoking the system matrix at inference, supporting real-time PAT reconstruction.
