In the scanning process of the embodiment, the injection parameter editing operation of the high-pressure injector can be reduced, and the scanning flow is optimized. Meanwhile, the customized injection protocol of the high-pressure injector and the execution of the enhanced scanning are mutually independent, a master technician or an advanced technician can execute the protocol customization operation, and a common technician only needs to execute the scanning without customizing the protocol, thereby reducing the qualification requirement of the technician operating the enhanced scanning system.
