Our work on “3D-printed iodine-ink CT phantom for radiomics feature extraction – advantages and challenges“, M. Bach et al., has been published in Medical Physics.
To test and validate novel CT techniques, such as texture analysis in radiomics, repeat measurements are required. In this work, we analyze in detail the quantitative characteristics of iodine-ink based 3D-printed phantom. Design considerations and the manufacturing process are described. Potential pitfalls for radiomics testing for such phantoms are presented.
