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 invention provides for a medical instrument (100) comprising a processor (134) and a memory (138) containing machine executable instructions (140). Execution of the machine executable instructions causes the processor to: receive (200) a first magnetic resonance image data set (146) descriptive of a first region of interest (122) of a subject (118) and receive (202) at least one second magnetic resonance image data set (152, 152′) descriptive of a second region of interest (124) of the subject. The first region of interest at least partially comprises the second region of interest. Execution of the machine executable instructions further cause the processor to receive (204) an analysis region (126) within both the first region of interest and within the second region of interest. Execution of the machine executable instructions further cause the processor to construct (206) a cost function comprising an intra-scan homogeneity measure separately for the first magnetic resonance image data set and separately for each of the at least one second magnetic resonance image data set. The cost function further comprises an inter-scan similarity measure calculated using both the first magnetic resonance image data set and each of the at least one second magnetic resonance image data set. Execution of the machine executable instructions further cause the processor to by performing an optimization (208) of the cost function by calculating a first intensity correction map (154) for the first magnetic resonance image data set using an intensity correction algorithm within the analysis region and at least one second intensity correction map (156) for each of the at least one second magnetic resonance image data set within the analysis region. Execution of the machine executable instructions further cause the processor to calculate (210) a first corrected magnetic resonance image (158) descriptive of the analysis region using the first magnetic resonance image data set and the first intensity correction map. Execution of the machine executable instructions further cause the processor to calculate (212) at least one second corrected magnetic resonance image (160) descriptive of the analysis region using the at least at least one second magnetic resonance image data set and the at least one second intensity correction map.

Abstract: A system and method are provided for interactive editing of a mesh which has been applied to a three-dimensional (3D) image to segment an anatomical structure shown therein. To facilitate the interactive editing of the applied mesh, a view of the 3D image is generated which shows a mesh part to be edited, with the view being established based on a local orientation of the mesh part. Advantageously, the view may be generated to be substantially orthogonally to the mesh part, or to a centerline of the anatomical structure which is determined as a function of the mesh part. Accordingly, an orthogonal view is established which facilitates the user in carrying out the editing action with respect to the mesh part. It is therefore not needed for the user to manually navigate through the 3D image to obtain a view which is suitable for mesh editing, which is typically time consuming.

Abstract: The present invention relates to an X-ray radiograph apparatus (10). It is described to placing (110) an X-ray source (20) relative to an X-ray detector (30) to form an examination region for the accommodation of an object, wherein, a reference spatial coordinate system is defined on the basis of geometry parameters of the X-ray radiography apparatus. A camera (40) is located (120) at a position and orientation to view the examination region. A depth image of the object is acquired (130) with the camera within a camera spatial coordinate system, wherein within the depth image pixel values represent distances for corresponding pixels. A processing unit (50) transforms (140), using a mapping function, the depth image of the object within the camera spatial coordinate system to the reference spatial coordinate system, wherein, the camera position and orientation have been calibrated with respect to the reference spatial coordinate system to yield the mapping function that maps a spatial point within the camera spatial coordinate system to a corresponding spatial point in the reference spatial coordinate system. A synthetic image is generated (150) within the reference spatial coordinate system. The synthetic image is output (160) with an output unit (60).
