Image-conditioned latent rectified flow models for 3D medical anomaly localisation

Frontiers in Radiology
IntroductionReconstruction-based methods offer a promising solution for unsupervised anomaly detection in medical imaging tasks. These methods train generative models on healthy data alone and identify anomalies as deviations between an input image and ...

Analytical evaluation of intact human tissues using mid-frequency scanning acoustic microscopy at the mesoscopic scale

Journal of Analytical Science and Technology
Conventional histological examination requires irreversible sectioning, consuming tissue and precluding three-dimensional analysis. This limitation is particularly problematic for archival specimens and forensic investigations.

Spiral scanning and self-supervised image reconstruction enable ultra-sparse sampling multispectral photoacoustic tomography

Photoacoustics
Multispectral photoacoustic tomography (PAT) is an imaging modality that utilizes the photoacoustic effect to achieve non-invasive and high-contrast imaging of internal tissues but also molecular functional information derived from multi-spectral ...
