MindEye2: Shared-Subject Models Enable fMRI-To-Image With 1 Hour of Data Open
Reconstructions of visual perception from brain activity have improved tremendously, but the practical utility of such methods has been limited. This is because such models are trained independently per subject where each subject requires …

A Vision-Language Foundation Model to Enhance Efficiency of Chest X-ray Interpretation Open
Over 1.4 billion chest X-rays (CXRs) are performed annually due to their cost-effectiveness as an initial diagnostic test. This scale of radiological studies provides a significant opportunity to streamline CXR interpretation and documenta…

Scalable High-Resolution Pixel-Space Image Synthesis with Hourglass Diffusion Transformers Open
We present the Hourglass Diffusion Transformer (HDiT), an image generative model that exhibits linear scaling with pixel count, supporting training at high-resolution (e.g. $1024 \times 1024$) directly in pixel-space. Building on the Trans…

Label- and slide-free tissue histology using 3D epi-mode quantitative phase imaging and virtual hematoxylin and eosin staining Open
Histological staining of tissue biopsies, especially hematoxylin and eosin (H&E) staining, serves as the benchmark for disease diagnosis and comprehensive clinical assessment of tissue. However, the typical formalin-fixation, paraffin-embe…

Reconstructing the Mind's Eye: fMRI-to-Image with Contrastive Learning and Diffusion Priors Open
We present MindEye, a novel fMRI-to-image approach to retrieve and reconstruct viewed images from brain activity. Our model comprises two parallel submodules that are specialized for retrieval (using contrastive learning) and reconstructio…

RoentGen: Vision-Language Foundation Model for Chest X-ray Generation Open
Multimodal models trained on large natural image-text pair datasets have exhibited astounding abilities in generating high-quality images. Medical imaging data is fundamentally different to natural images, and the language used to succinct…

Pilot study of fluorescence imitating brightfield imaging for rapid, slide‐free dermatopathology Open
Background Fluorescence imitating brightfield imaging (FIBI) is a novel alternative microscopy method that can image freshly excised, non‐sectioned tissue. We examine its potential utility in dermatopathology by examining readily available…

Slide-free MUSE Microscopy to H&E Histology Modality Conversion via Unpaired Image-to-Image Translation GAN Models Open
MUSE is a novel slide-free imaging technique for histological examination of tissues that can serve as an alternative to traditional histology. In order to bridge the gap between MUSE and traditional histology, we aim to convert MUSE image…
