RadiomicsJ: a library to compute radiomic features

Despite the widely recognized need for radiomics research, the development and use of full-scale radiomics-based predictive models in clinical practice remains scarce. This is because of the lack of well-established methodologies for radiomic research and the need to develop systems to support radiomic feature calculations and predictive model use. Several excellent programs for calculating radiomic features have been developed. However, there are still issues such as the types of image features, variations in the calculated results, and the limited system environment in which to run the program. Against this background, we developed RadiomicsJ, an open-source radiomic feature computation library. RadiomicsJ will not only be a new research tool to enhance the efficiency of radiomics research but will also become a knowledge resource for medical imaging feature studies through its release as an open-source program.
