    Abstract: The present invention relates to a system (10) and related method for planning a tomographic image acquisition of an object to be imaged by a tomographic imaging scanner (20). The system comprises an input (12) for receiving a 3D pre-scan image of the object and a camera system (14) for capturing 3D image information of the object. The system comprises a processor (16) for determining corresponding image features in the camera image and the pre-scan image. The processor determines an image transformation that relates the corresponding image features to each other, such that the object as represented by the pre-scan image can be transformed to the orientation, position and/or deformation of the object represented in the camera image. The processor plans the image acquisition, in which the pre-scan image is used to determine parameters including scan range. An output (18) outputs a signal representative of the determined plan.

    Abstract: The present invention provides for means for linking breast lesion locations across imaging studies. In particular, a generic three-dimensional representation of the female breast is used. Automatic translation of the lesion location into standard clinical terminology and aligning the breast model with individual patient images is comprised. Moreover, a mechanism for linking image locations showing a lesion to a location in the breast model is presented. If desired, a region of interest can be calculated by a region of interest definition module that predicts a region of interest of a known lesion in terms of the breast model representation in a new imaging study.

    Abstract: The present invention relates to assisting scapula positioning in chest X-ray imaging. Provided is a system and related method for assisting subject positioning in chest X-ray imaging, wherein the system comprises an optical detection device (110), a user interface (130), and a processor (120), connected to the optical detection device (110) and the user interface (130). Thereby, the processor (120) is configured to receive an optical image signal of a rear view of the subject(S), determine a current positioning of a scapula of the subject(S) based on the optical image signal, wherein the current positioning of the scapula is assessed as to whether and/or to which extent it would overlap or would not overlap a lung field of the subject to be imaged and determine a feedback for positioning the subject(S) and/or its scapula based on the determined current positioning of the scapula. The user interface (130) is configured to provide the feedback for positioning the subject.

    Abstract: The invention provides for a medical apparatus (100, 300, 400) comprising a subject support (102) configured for moving a subject (106) from a first position (124) to a second position (130) along a linear path (134). The subject support comprises a support surface (108) for receiving the subject. The subject support is further configured for positioning the subject support in at least one intermediate position (128). The subject support is configured for measuring a displacement (132) along the linear path between the first position and the at least one intermediate position. Each of the at least one intermediate position is located between the first position and the second position. The medical apparatus further comprises a camera (110) configured for imaging the support surface in the first position. Execution of machine executable instructions 116 cause the a processor (116) controlling the medical apparatus to: acquire (200) an initial image (142) with the camera when the subject support is in the first position; control (202) the subject support to move the subject support from the first position to the second position; acquire (204) at least one intermediate image (144) with the camera and the displacement for each of the at least one intermediate image as the subject support is moved from the first position to the second position; and calculate (206) a height profile (150, 600, 604) of the subject by comparing the initial image and the at least one intermediate image. The height profile is at least partially calculated using the displacement. The height profile is descriptive of the spatially dependent height of the subject above the support surface.

    Abstract: The appropriate positioning of a patient in an X-Ray imaging system can present difficulties for medical professional owing, on one hand to the small size of important anatomical aspects which need to be captured in X-Ray images, and on the other hand to the significant movements in a field of view presented by a typical patient. The present application proposes to obtain an image of the position of a patient in the field of view at approximately the same time that an initial X-Ray image is obtained. If it proves necessary to obtain a subsequent X-Ray image with updated field of view settings (for example, collimation parameters), the movement of the patient at the point of taking the second image is factored into the provision of updated field of view settings.
