    摘要： The invention is related to a method for providing guidance data (30, 41) for positioning a region of interest (20, 31, 41, 56) of a subject (54), an X-ray source (52), and an X-ray detector (21, 34, 53). The method comprises: obtaining, by a processor (11), current positioning data of at least one palpable bony landmark (23, 33) of the region of interest (20, 31, 41, 56) from a measuring device (58), wherein the current positioning data is derived from a palpation of the at least one palpable bony landmark (23, 33) (S10); obtaining, by the processor (11), current positioning data of the X-ray source (52) and of the X-ray detector (21, 34, 53) (S20); determining, by the processor (11), guidance data (30, 41) for positioning the region of interest (20, 31, 41, 56), the X-ray source (52) and the X-ray detector (21, 34, 53) by utilizing a parametric 3D model and the obtained current positioning data of the at least one palpable bony landmark (23, 33), of the X-ray source (52), and of the X-ray detector (21, 34, 53) (S30); providing, by the processor (11), the guidance data (30, 41) (S40).

    摘要： An X-ray imaging system (100) includes an X-ray source (110) and an X-ray detector (120) that are separated by an examination region (150) for performing an X-ray imaging operation on an object (160). A processor (140) is configured to identify (S120) one or more internal structures (180) within the object (160), based on a comparison of depth sensor data representing a three-dimensional surface (170) of the object (160), with an anatomical model comprising the one or more internal structures (180). The processor (140) is also configured to compute (S130), using the depth sensor data and the identified one or more internal structures (180), a surface projection (190) of the one or more internal structures, on the surface (170) of the object (160), from a perspective of the X-ray source (110); and to output (S140) an image representation of the surface projection (190) for displaying as an overlay on the surface (170) of the object (160).

    摘要： A computer-implemented method for positioning a subject in medical imaging, comprising: receiving a first image (20) of a region of interest (14, 16) of the subject (S10); determining first positioning data based on the first image (20), wherein the first positioning data indicates an alignment of the region of interest (14, 16) relative to a first image acquisition unit used to acquire the first image (20) (S20); determining guidance data based on the first positioning data, wherein the guidance data comprises a guidance for an alignment of the region of interest (14, 16) relative to a second image acquisition unit used to acquire a second image (60) from a current alignment to a target alignment, wherein the target alignment is to correspond to that derived from the first positioning data (S30); providing the guidance data for acquiring the second image (60) (S40).
