Guidance for positioning a patient in medical imaging

A device for positioning a subject in medical imaging, comprising:

• a receiver configured to receive a first image of a region of interest of the subject;
• at least one processor configured to:
• determine first positioning data based on the first image, wherein the first positioning data indicates an alignment of the region of interest relative to a first image acquisition unit used to acquire the first image;
• determine guidance data based on the first positioning data, wherein the guidance data comprises a guidance for an alignment of the region of interest relative to a second image acquisition unit used to acquire a second image from a current alignment of the region of interest to the second image acquisition unit to a target alignment of the region of interest to the second image acquisition unit, wherein the target alignment is to correspond to an alignment of the region interest relative to a first image acquisition unit derived from the first positioning data;
• provide the guidance data for acquiring the second image.

A non-transitory computer-readable medium for storing executable instructions, which cause a method to be performed to position a subject in medical imaging, the method comprising:

• receiving a first image of a region of interest of the subject;
• determining first positioning data based on the first image, wherein the first positioning data indicates an alignment of the region of interest relative to a first image acquisition unit used to acquire the first image;
• determining guidance data based on the first positioning data, wherein the guidance data comprises a guidance for an alignment of the region of interest relative to a second image acquisition unit used to acquire a second image from a current alignment of the region of interest to the second image acquisition unit to a target alignment of the region of interest to the second image acquisition unit, wherein the target alignment corresponds to an alignment of the region of interest relative to a first image acquisition unit derived from the first positioning data;
• providing the guidance data for acquiring the second image.
