Abstract
A multi-purpose automated radiomics workflow is proposed which facilitates the extraction of a bank of radiomics features for a diversity of imaging modalities and patient pathologies. It is versatile enough to provide a robust extraction of the radiomics features without requiring manual corrections even when the patient pathology is characterized by multisite lesions and thus multiple segmented sites, such as for instance multiple tumors or metastasis sites in late cancer stages.
Claims18
A computer-implemented method for producing a bank of radiomics features from the radiological imaging data of a patient pathology having multiple lesion sites, the method comprising the steps of:
- a) receiving radiological imaging data of the patient from a database of medical data;
- b) segmenting the radiological imaging data to produce at least two connected components, each connected component characterizing a lesion site, the connected components forming an object of interest to characterize a pathology of the patient;
- c) extracting a bank of radiomics features from the at least two connected components;
- d) storing the bank of radiomics features in a database of digital health features;
- characterized in that:
- extracting a bank of radiomics features comprises a step of producing at least two values selected from:
- a total value, an average value and/or a maximum value of at least one radiomics feature calculated from all the connected components.
