Synthesized DeepLesion

1) Descriptions:

• Clean CT Images: Download 1200 CT images from the DeepLesion dataset
• Simulation Protocol: Refer to [1][2] with the imaging parameters in bulid_geometory.py
• Simulation Tool: Python.
• Training Data: Pairing 1000 clean images with 90 metals collected from [1]. Following [2], in each training iteration, we randomly chose one CT image with synthesized metal artifacts from the pool of 90 different metal mask pairs

• Testing Data: Pairing another 200 clean CT images with another 10 metals collected from [1] with sizes [2061, 890, 881, 451, 254, 124, 118, 112, 53, 35]
