F2FLDM: Latent Diffusion Models with Histopathology Pre-Trained Embeddings for Unpaired Frozen Section to FFPE Translation

no code implementations19 Apr 2024 Man M. Ho, Shikha Dubey, Yosep Chong, Beatrice Knudsen, Tolga Tasdizen

The Frozen Section (FS) technique is a rapid and efficient method, taking only 15-30 minutes to prepare slides for pathologists' evaluation during surgery, enabling immediate decisions on further surgical interventions.

DISC: Latent Diffusion Models with Self-Distillation from Separated Conditions for Prostate Cancer Grading

no code implementations19 Apr 2024 Man M. Ho, Elham Ghelichkhan, Yosep Chong, Yufei Zhou, Beatrice Knudsen, Tolga Tasdizen

Latent Diffusion Models (LDMs) can generate high-fidelity images from noise, offering a promising approach for augmenting histopathology images for training cancer grading models.

StainDiffuser: MultiTask Dual Diffusion Model for Virtual Staining

no code implementations17 Mar 2024 Tushar Kataria, Beatrice Knudsen, Shireen Y. Elhabian

Hematoxylin and Eosin (H&E) staining is the most commonly used for disease diagnosis and tumor recurrence tracking.

Cell Segmentation Image Generation

Structural Cycle GAN for Virtual Immunohistochemistry Staining of Gland Markers in the Colon

no code implementations25 Aug 2023 Shikha Dubey, Tushar Kataria, Beatrice Knudsen, Shireen Y. Elhabian

Quantitative metrics such as FID and SSIM are frequently used for the analysis of generative models, but they do not correlate explicitly with higher-quality virtual staining results.

To pretrain or not to pretrain? A case study of domain-specific pretraining for semantic segmentation in histopathology

1 code implementation6 Jul 2023 Tushar Kataria, Beatrice Knudsen, Shireen Elhabian

In this study, we compare the performance of gland and cell segmentation tasks with histopathology domain-specific and non-domain-specific (real-world images) pretrained weights.

Cell Segmentation Segmentation +2

Unsupervised Domain Adaptation for Medical Image Segmentation via Feature-space Density Matching

no code implementations9 May 2023 Tushar Kataria, Beatrice Knudsen, Shireen Elhabian

Nonetheless, they often fail to generalize when there is a significant domain (i. e., distributional) shift between the training (i. e., source) data and the dataset(s) encountered when deployed (i. e., target), necessitating manual annotations for the target data to achieve acceptable performance.

Visual attention analysis of pathologists examining whole slide images of Prostate cancer

no code implementations17 Feb 2022 Souradeep Chakraborty, Ke Ma, Rajarsi Gupta, Beatrice Knudsen, Gregory J. Zelinsky, Joel H. Saltz, Dimitris Samaras

To quantify the relationship between a pathologist's attention and evidence for cancer in the WSI, we obtained tumor annotations from a genitourinary specialist.
