数据说明

Conditions: Cystic Fibrosis. Dynamic chest X-ray (DCR) records images of the chest in motion in a ‘recording’ over 10-20 seconds. This is essentially a video x-ray of the chest and associated structures involved in breathing. The images acquired by the DCR can be processed using computer algorithm and key quantitative measures derived (such as diaphragm movement speed and changes in lung field area). Due to the way the X-ray is acquired, this is relatively lower radiation than other video caption imaging available (such as fluoroscopy). The time component of the imaging (vs static imaging) also opens up possibilities for clinical utilisation beyond imaging techniques that are already available without losing clinical information that a conventional static x-ray provides. The direct visualization of the chest and lung field in motion may therefore provide clinically relevant information about respiratory function. It may be possible that relating DCR to conventional lung function testing allows it to be used as a surrogate tool for assessing pulmonary function. Alternatively, it may provide different parameters of lung function that don’t directly correlate with conventional testing but are of themselves clinically relevant. Cystic fibrosis (CF) is an autosomal recessive genetic condition resulting in viscid, dehydrated luminal secretions. It has multi-system consequences but is usually characterised by a cycle of recurring lung infections and inflammation resulting in progressive lung damage. A key clinical investigation for people with cystic fibrosis (pwCF), as well as many other chest conditions, is a spirometry breathing test. Despite this spirometry can be poorly tolerated in individuals with underlying respiratory conditions. Patient factors combined with the ease and speed of acquiring DCR may mean it is better tolerated than conventional pulmonary function techniques such as spirometry. No previous studies have directly compared DCR with simultaneous breathing tests (such as spirometry)

数据加载示例（图像类）

from PIL import Image
import glob, os

files = (glob.glob(os.path.join(path, "**", "*.png"), recursive=True)
       + glob.glob(os.path.join(path, "**", "*.jpg"), recursive=True)
       + glob.glob(os.path.join(path, "**", "*.tif"), recursive=True))
print("图像文件数:", len(files))
img = Image.open(files[0]); print("尺寸/模式:", img.size, img.mode)

# torchvision Dataset 方式:
# from torchvision import datasets
# ds = datasets.ImageFolder(path)  # 要求 子目录=类别
