This hook can be used to define a function that return a boolean which decided the validity of the mode based on StudyInstanceUID and modalities that are in the study.

For instance, for pet-ct mode, both PT and 'CT' modalities should be available inside the study.

export default function mode() {
  return {
    id: '',
    displayName: '',
    isValidMode: ({ modalities, StudyInstanceUID }) => {
      const modalities_list = modalities.split('\\');
      const validMode = ['CT', 'PT'].every(modality => modalities_list.includes(modality));
      return validMode;
    },
    /*
    ...
    */
  }
}
