Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Imaging data and medical records of patients will be automatically extracted through the hospital's imaging system (PACS system). All experimental data will be stored electronically and securely preserved by the study designer on a dedicated encrypted computer, with strict access restrictions. Patient personal information will be replaced with identification numbers/codes.
