    摘要: A system and method of diagnostic imaging with reduced x-ray exposure to the scan subject during scanning includes acquiring (206) a set of cardiac signals or other motion (cardiac mechanical motion or respiratory motion) related signals and determining (208) an imaging profile therefrom. Pursuant to the imaging profile, voltage applied to an x-ray source is modulated (210) to provide an energizing voltage during primary data acquisition stages and a reduced voltage (214) during secondary or non-data acquisition stages. Voltage modulation repeats (217) until sufficient data for image reconstruction (218) has been acquired.

    摘要: The present invention is directed to a networked scanner environment (160) wherein each scanner (176, 178, 180, 182, 184) is communicable with one or more databases (170, 194) configured to store data associated with previously executed imaging sessions. The one or more databases (170, 194) may be queried by a user to determine, based on a set of user inputs, an historical evaluation of the prior imaging sessions conducted in accordance with scan parameters similar to the scan parameters of an imminent imaging session. The present invention includes a global database (194) that is accessible by a series of remotely located imaging systems as well as includes one or more databases (170) particular to a specific treatment facility (160) housing one or more imaging scanners. The present invention is also applicable with a stand-alone imaging system (180, 182, 184) having a database local to that particular imaging system (180, 182, 184) for storing and accessing data associated with imaging sessions conducted on that particular imaging system.

    摘要: A system and method of medical imaging is designed to reduce a patient's X-ray exposure during scanning (112). The system automatically generates a default noise index (106) from a received set of scan parameter values that specifies a desired tube current of an X-ray source to use during the scanning of a patient. The default noise index (106) can then be overridden to select a preferred noise index based upon a desired diagnostic quality for a particular volume of interest (VOI) and a diagnostic objective.
