Masks of problematic areas (ground glass opacity, ect) in chest radiography #166

Open AlexTS1980 opened 3 years ago

AlexTS1980 commented 3 years ago

Are there any chest radiography datasets with masks of COVID correlates like GGO, or at least bounding boxes. I only found one article, Weakly Labeled Data Augmentation for Deep Learning: A Study on COVID-19 Detection in Chest X-Rays, but no links to datasets. I found quite a few for CT scans, but I need for chest x-rays too.

Check out the last two annotations listed here: https://github.com/ieee8023/covid-chestxray-dataset#annotations I believe they have more than just lung annotations.

Thanks. I'm building a model that can generalize to arbitrary datasets. Do you know any CT/xray masks for non-COVID pneumonia cases?

Here are masks for the RSNA pneumonia dataset: https://github.com/mlmed/torchxrayvision/blob/master/scripts/xray_masks.ipynb

Awsm thanks!

If you find anymore mask datasets please share!

RSNA are more like bounding boxes than masks, but it's probably the best there is. The only x-ray lesion masks I found are these: https://github.com/GeneralBlockchain/covid-19-chest-xray-segmentations-dataset

I found a very good chest ct scan dataset that I used for my models (https://github.com/AlexTS1980/COVID-Single-Shot-Model) here: http://ncov-ai.big.ac.cn/download. It's 750 slices + pixel masks (lungs, GGO, C).

This dataset will hopefully be released soon: https://daa63e84b26d.ngrok.io/
