The official codes for PMC-VQA: Visual Instruction Tuning for Medical Visual Question Answering

We propose a generative-based model for medical visual understanding by aligning visual information from a pre-trained vision encoder with a large language model, and establish a scalable pipeline to construct a large-scale medical visual question-answering dataset, named PMC-VQA, which contains 227k VQA pairs of 149k images that cover various modalities or diseases.

The dataset is available at Huggingface

The model checkpoints are available at MedVInT-TE and MedVInT-TD. The previous checkpoint of MedVInT-TD was mistakenly uploaded. We have rectified the issue and updated the model's checkpoint on July 31. Now, you can access the correct and improved version of the model.
