Apparatus for determining an orientation of a patient's chest
An orientation of a patient's chest is determined by an apparatus and method. According to the invention, a camera image of a patient comprising image data of the patient's chest is received, wherein the camera image is acquired with an optical camera. Further, an X-ray radiograph of the patient's chest with an X-ray imaging axis extending from an X-ray source to an X-ray detector is received. Then, the camera image and the X-ray radiograph are provided to at least one processor. Further, information relating to a clavicle to spinous process distance of the patient is then determined using the camera image. Finally, an orientation of the patient's chest in the X-ray radiograph with respect to the X-ray imaging axis is determined using the camera image, the X-ray radiograph, and the information relating to the clavicle to spinal process distance of the patient.

receive an X-ray radiograph of the patient's chest with an X-ray imaging axis extending from an X-ray source to an X-ray detector;
determine a clavicle to spinous process distance of the patient using the camera image; and
in the X-ray radiograph, obtain an estimation of the patient's chest rotation about a longitudinal axis of the patient using the camera image, the X-ray radiograph, and the clavicle to spinous process distance of the patient.
2. The apparatus according to claim 1 , wherein the at least one processor is configured to determine information relating to one or more of: a left clavicle head, a right clavicle head, and a spinous process of the patient, and wherein obtaining the estimation of the patient's chest rotation comprises using the information relating to one or more of: the left clavicle head, the right clavicle head, and the spinous process of the patient.
3. The apparatus according to claim 2 , wherein the information relating to the left clavicle head, the right clavicle head, and the spinous process of the patient comprises locations in the X-ray radiograph of one or more of the left clavicle head, the right clavicle head, and the spinous process of the patient.
4. The apparatus according to claim 2 , wherein the information relating to the left clavicle head, the right clavicle head, and the spinous process of the patient comprises relative location information in the X-ray radiograph of two or more of the left clavicle head, the right clavicle head, and the spinous process of the patient.
5. The apparatus according to claim 2 , wherein the information relating to the left clavicle head, the right clavicle head, and the spinous process of the patient comprises a distance in the X-ray radiograph between the left clavicle head and the right clavicle head.
6. The apparatus according to claim 2 , wherein the information relating to the left clavicle head, the right clavicle head, and the spinous process of the patient comprises a distance in the X-ray radiograph between the left clavicle head and the spinous process.
7. The apparatus according to claim 2 , wherein the information relating to the left clavicle head, the right clavicle head, and the spinous process of the patient comprises a distance in the X-ray radiograph between the right clavicle head and the spinous process.
8. The apparatus according to claim 2 , wherein the information relating to the left clavicle head, the right clavicle head, and the spinous process of the patient comprises locations of the left clavicle head, the right clavicle head, and the spinous process in the X-ray radiograph relative to each other.
9. The apparatus according to claim 2 , wherein the information relating to the left clavicle head, the right clavicle head, and the spinous process of the patient comprises distances between the left clavicle head, the right clavicle head, and the spinous process in the X-ray radiograph with respect to each other.
10. A computer-implemented method for determining an orientation of a patient's chest, comprising:
receiving a camera image of a patient comprising image data of the patient's chest, wherein the camera image is acquired with an optical camera;
receiving an X-ray radiograph of the patient's chest with an X-ray imaging axis extending from an X-ray source to an X-ray detector;
providing the camera image and the X-ray radiograph to at least one processor;
