Abstract: A CT scanner for performing a brain scan performs a low dose 3D scan with a first field of view. By analyzing the low dose 3D scan, for example using landmark detection, a proposed field of view is obtained for a full dose 3D brain scan. A representation of the proposed field of view is displayed, and a final field of view is generated, as the proposed field of view or an updated version of the proposed field of view provided by a user of the CT scanner.

Abstract: A method is provided for analyzing survey imaging data. The method comprises acquiring first image data with a first imaging protocol covering a first FOV, processing the data with an anatomical analysis program or routine to detect at least a portion of a target anatomy, and performing a coverage check adapted to determine whether the target anatomy is fully covered within the first FOV. Second image data is subsequently acquired in accordance with a second imaging protocol defining a second FOV. The second imaging protocol may be: the same as the first, but wherein the results of the coverage check are stored and linked with the second image data for later use; different to the first and wherein the results of the coverage check are output to a user interface and a user input responsive thereto is used to determine the second scan protocol; or different to the first, but wherein an adjusted second scan protocol is automatically determined.
