Abstract

An X-ray imaging guiding system for positioning a region of interest of a patient for X-ray image acquisition includes an X-ray detector arrangement, and graphical positioning information. The graphical positioning information includes a graphical target anatomy representation. The graphical target positioning information is provided in spatial relation with the X-ray detector arrangement. The graphical target anatomy representation indicates a target position of a respective anatomy of the patient for a determined X-ray image acquisition. Further, the graphical positioning information is adaptable in accordance with the determined X-ray image acquisition.

First claim

The invention claimed is:

1. An X-ray imaging guiding system for positioning a patient for X-ray image acquisitions, comprising:
an X-ray detector arrangement;
and
a controller configured to provide graphical positioning information in spatial relation with the X-ray detector arrangement,
wherein the graphical positioning information comprises a graphical target anatomy representation,
wherein the graphical target anatomy representation indicates a target position of an underlying target organ of the patient for a determined X-ray image acquisition, and
wherein the controller is further configured to link the target position to a patient position of the patient to change the target position with a movement of the patient and present the target position at a location of the underlying target organ.

2. The X-ray imaging guiding system according to claim 1 , further comprising a projection arrangement configured to project visible light, and wherein the graphical target anatomy representation is provided as a visible light projection in a projection direction towards the detector arrangement.

3. The X-ray imaging guiding system according to claim 2 , wherein the graphical positioning information comprises a target indicator indicating a predetermined area of the X-ray detector, and wherein the graphical target anatomy representation and the target indicator are provided in a predetermined spatial relation.

4. The X-ray imaging guiding system according to claim 2 , wherein a patient positioning arrangement is provided detecting the movement of the patient, wherein the graphical target anatomy representation is linked to the movement of the patient, wherein a target indicator is provided indicating a predetermined area of the X-ray detector, and wherein the graphical target anatomy representation and the target indicator can be brought into a determined spatial relation through the respective motion of the X-ray detector arrangement and the patient in relation to each other.

5. The X-ray imaging guiding system according to claim 1 , wherein the X-ray detector arrangement comprises a visible surface configured to be located in an X-ray radiation beam during the X-ray image acquisition;
wherein the graphical positioning information is provided on the visible surface; and
wherein the visible surface is provided at least as one of the group of: i) a detector cover; ii) a patient support surface; or iii) a patient abutting surface.

6. The X-ray imaging guiding system according to claim 5 , wherein the visible surface comprises an adaptable display surface.

7. The X-ray imaging guiding system according to claim 6 , wherein the adaptable display surface is provided with an e-paper coating structure.

8. The X-ray imaging guiding system according to claim 6 , wherein the adaptable display surface is light emitting; and
wherein a light emitting layer with at least one light emitting element is arranged in front of a detector photodiode layer.

9. The X-ray imaging guiding system according to claim 8 , wherein the at least one light emitting element is provided as an organic light-emitting diode.

10. The X-ray imaging guiding system according to claim 8 , wherein the at least one light emitting element is provided as a reset light source for a scintillator of the X-ray detector arrangement.

11. The X-ray imaging guiding system according to claim 6 , wherein the adaptable display surface is light emitting; and
wherein light emitting elements and detector photodiode elements are arranged in an interlaced pattern as a mixed layer.

12. The X-ray imaging guiding system according to claim 5 , wherein the graphical positioning information comprises instructions related to the determined X-ray image acquisition;
wherein the instructions are provided for an interaction of a user; and
wherein the visible surface comprises areas or portions ( 68 ) which are activatable by the user for entering feedback upon the instructions.

13. The X-ray imaging guiding system according to claim 1 , wherein the graphical positioning information is maintained during an X-ray imaging procedure.

14. An X-ray imaging system, comprising:
an X-ray source; and
a guiding system according to claim 1 ;
wherein the X-ray source is configured to radiate an X-ray beam towards the X-ray detector arrangement; and
wherein the graphical positioning information is provided for guiding in positioning a region of interest of the patient between the X-ray source and the X-ray detector arrangement for X-ray image acquisition.

15. The X-ray imaging guiding system of claim 1 , wherein the graphical positioning information further comprises a target indicator indicating a predetermined area of the X-ray detector, and wherein a location of the target indicator remains fixed while the target position of the patient changes with the movement of the patient.

16. A method for guiding in positioning a region of interest of a patient for X-ray image acquisition, comprising acts of:
providing graphical positioning information comprising a graphical target anatomy representation;
displaying the graphical target anatomy representation in spatial relation with an X-ray detector arrangement, wherein the graphical target anatomy representation indicates a target position of an underlying target organ of the patient for a determined X-ray image acquisition;
linking the target position to a patient position of the patient to move the target position with a movement of the patient; and
presenting the target position at a location of the underlying target organ.

17. The method according to claim 16 , wherein in the displaying act, the graphical target anatomy representation is provided as a visible light projection in a projection direction towards the X-ray detector arrangement.

18. The method according to claim 16 , wherein in the displaying act, the graphical positioning information is provided by an adaptable display surface on a visible surface of the X-ray detector arrangement, wherein after positioning of the region of interest of the patient, an actual field of view is determined by detecting a reflected intensity from light provided by a light emitting adaptable display surface.

19. A non-transitory computer-readable medium comprising computer instructions for guiding in positioning a region of interest of a patient for X-ray image acquisition which, when executed by a processor, configure the processor to perform acts of:
providing graphical positioning information comprising a graphical target anatomy representation;
causing display of the graphical target anatomy representation in spatial relation with an X-ray detector arrangement, wherein the graphical target anatomy representation indicates a target position of an underlying target organ of the patient for a determined X-ray image acquisition;
linking the target position to a patient position of the patient to move the target position with a movement of the patient; and
causing presentation of the target position at a location of the underlying target organ.
