Method for providing guidance data in an x-ray system

A device for providing guidance data for positioning a region of interest of a subject, an X-ray source, and an X-ray detector, comprising:

• a processor configured to:
• obtain current positioning data of at least one palpable bony landmark of the region of interest from a measuring device, wherein the current positioning data is derived from a palpation of the at least one palpable bony landmark;
• obtain current positioning data of the X-ray source and of the X-ray detector;
• determine guidance data for positioning the region of interest, the X-ray source and the X-ray detector by utilizing i) a parametric 3D model configured to describe a pose of the region of interest and ii) the obtained current positioning data of the at least one palpable bony landmark, of the X-ray source, and of the X-ray detector;
• and
• provide the guidance data, wherein obtaining the current positioning data of the at least one palpable bony landmark of the region of interest comprises:
• measuring a spatial position of at least a fingertip of a soft tissue palpation robot palpating the least one palpable bony landmark, or
• indicating, via a trigger signal, that at least one fingertip of a soft tissue palpation robot palpates the at least one palpable bony landmark.

A non-transitory computer-readable medium for storing executable instructions, which cause a method for providing guidance data for positioning a region of interest of a subject, an X-ray source and an X-ray detector, the method comprising:

• obtaining current positioning data of at least one palpable bony landmark of the region of interest from a measuring device, wherein the current positioning data is derived from a palpation of the at least one palpable bony landmark;
• obtaining current positioning data of the X-ray source and of the X-ray detector;
• determining guidance data for positioning the region of interest, the X-ray source and the X-ray detector by i) utilizing a parametric 3D model configured to describe a pose of the region of interest and ii) the obtained current positioning data of the at least one palpable bony landmark, of the X-ray source, and of the X-ray detector;
• and
• providing the guidance data, wherein obtaining the current positioning data of the at least one palpable bony landmark of the region of interest comprises:
• measuring a spatial position of at least a fingertip of a soft tissue palpation robot palpating the least one palpable bony landmark, or
• indicating, via a trigger signal, that at least one fingertip of a soft tissue palpation robot palpates the at least one palpable bony landmark.
