generate-cxr

This BlipForConditionalGeneration model generates realistic radiology reports given an chest X-ray and a clinical indication (e.g. 'RLL crackles, eval for pneumonia').

How to Get Started with the Model

from PIL import Image
from transformers import BlipForConditionalGeneration, BlipProcessor

# read in the model
processor = BlipProcessor.from_pretrained("nathansutton/generate-cxr")
model = BlipForConditionalGeneration.from_pretrained("nathansutton/generate-cxr")

# your data
my_image = 'my-chest-x-ray.jpg'
my_indication = 'RLL crackles, eval for pneumonia'

# process the inputs
inputs = processor(
    images=Image.open(my_image), 
    text='indication:' + my_indication,
    return_tensors="pt"
)

# generate an entire radiology report
output = model.generate(**inputs,max_length=512)
report = processor.decode(output[0], skip_special_tokens=True)

Training Details

This model was trained by cross-referencing the radiology reports in MIMIC-CXR with the images in the MIMIC-CXR-JPG. None are available here and require a data usage agreement with physionet.
