Table 2 Scoring for overall image quality.

From: The evaluation of the reduction of radiation dose via deep learning-based reconstruction for cadaveric human lung CT images

Score 1

Very poor (it is very difficult to detect structures and clearly evaluate their margins or internal properties)

Score 2

Poor (detection of structures is possible but it is difficult to clearly evaluate their margins or internal properties)

Score 3

Fair (margins or internals properties can be detected and are not inferior to the reference image)

Score 4

Better (detection of structures and the evaluation of their margins or internal properties was easier compared to the reference image)

Score 5

Excellent (detection of structures and the evaluation of their margins or internal properties was significantly easier compared to the reference image and there was no indistinct findings)
