摘要： An imaging workflow system includes a workstation for acquiring patient information and requesting a patient scan. The request for a patient scan includes scan information for performing the scan. A registration module receives the scan information and the patient information. The registration module automatically schedules the patient scan based on the scan information and the patient information. The registration module determines an imaging protocol based on the patient information and the scan information. An imaging module within an imaging system receives the imaging protocol. The imaging module automatically sets scan parameters based on the imaging protocol. The imaging system scans the patient based on the scan parameters to acquire image data. A user interface controls the patient scan. The user interface includes a display to display images generated from the acquired image data.
