    摘要： The invention relates to a scan region determining apparatus (12) for determining a scan region of a subject to be scanned by a scanning system (10) like a computed tomography system. A spatial transformation defining a registration of an overview image and a template image with respect to each other is determined, wherein initially the overview image and the template image are registered by using an element position indicator being indicative of a position of an element of the subject with respect to the overview image. A template scan region is defined with respect to the template image, wherein a final scan region is determined by projecting the template scan region onto the overview image by using the determined spatial transformation. The registration and thus the determination of the spatial transformation are very robust, which improves the quality of determining the final scan region.

    摘要： The present invention relates to a computer-implemented method of acquiring and combining medical images of a subject. A first medical image of a subject acquired by a medical imaging device with a first field of view is analyzed with respect to an encompassment of a region of interest of the subject. In case the region of interest of the subject is not fully encompassed in the first medical image, at least one second field of view of the medical imaging device is determined, and data to instruct the medical imaging device to acquire at least one second medical image of the subject with the at least one second field of view are generated. The at least one second medical image encompasses at least the part of the region of interest of the subject that is not encompassed in the first medical image. Further, the generated data are transmitted to the medical imaging device, and the at least one second medical image of the subject acquired with the at least one second field of view is received and combined with the first medical image to a combined medical image. The combined medical image encompasses the region of interest of the subject, and is providing to a user.

    摘要： 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.

    摘要： The invention relates to a system for assessing a pulmonary image which allows for an improved assessment with respect to lung nodules detectability. The pulmonary image is smoothed for providing different pulmonary images (20, 21, 22) with different degrees of smoothing, wherein signal values and noise values, which are indicative of the lung vessel detectability and the noise in these images, are determined and used for determining an image quality being indicative of the usability of the pulmonary image to be assessed for detecting lung nodules. Since a pulmonary image shows lung vessels with many different vessel sizes and with many different image values, which cover the respective ranges of potential lung nodules generally very well, the image quality determination based on the different pulmonary images (20, 21, 22) with different degrees of smoothing allows for a reliable assessment of the pulmonary image's usability for detecting lung nodules.
