Article on CT phantoms for radiomics published in Medical Physics

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.

CT datasets of the different phantom parts and overall phantom appearance. (a) Transversal CT image of the lung-part, (b) the liver part and (c) the test-patterns. (d) coronal CT image of the phantom. (e) cuboid black phantom positioned on a board in a CT scanner.
