## Abstract

An X-ray image diagnosis apparatus allows setting information indicating an object direction in a radiographed image without any errors. This invention is an X-ray detection apparatus which detects X-rays applied to an object and generates a radiographed image of the object. This apparatus includes a unit to display, in a display area, a symbol which has a form corresponding to the object and for which a vector representing a direction as a reference for the symbol is defined, a button to change the direction of the symbol displayed in the display area, and a unit to output information concerning the direction of the vector in association with a radiographed image of the object, when the direction of the symbol displayed in the display area is changed to match the direction of the object with the direction of the symbol displayed in the display area.

## Claims

### Claim 1

An X-ray detection apparatus which detects X-rays irradiated to an object and generates a radiographed image of the object, the apparatus comprising:
a detection area configured to detect the X-rays;
a display unit configured to display, in a display area, a symbol which has a form corresponding to the object and for which a vector representing a direction as a reference for the symbol is defined, wherein said display area is arranged on the same side of the object as is said detection area;
a changing unit configured to change the direction of the symbol displayed in the display area; and
an output unit configured to output information concerning a direction of the vector relative to the X-ray detection apparatus in association with a radiographed image of the object, when said changing unit changes the direction of the symbol displayed in the display area to match the direction of the symbol displayed in the display area with the direction of the object.

### Claim 2 (depends on 1)

The apparatus according to claim 1, wherein the vector is determined in advance for each of plural objects.

### Claim 3 (depends on 1)

The apparatus according to claim 1, further comprising a setting unit configured to set a region and posture of an object,
wherein said display unit displays, in the display area, a symbol corresponding to an object specified by a region and posture set by said setting unit.

### Claim 4 (depends on 1)

The apparatus according to claim 1, wherein said output unit outputs an image of the symbol upon superimposing the image on the radiographed image, when said changing unit changes the direction of the symbol displayed in the display area to match the direction of the symbol displayed in the display area with the direction of the object.

### Claim 5 (depends on 1)

The apparatus according to claim 1, wherein said output unit outputs information concerning a direction of the vector relative to the X-ray detection apparatus, as meta-data, upon adding the data to the radiographed image, when said changing unit changes the direction of the symbol displayed in the display area to match the direction of the symbol displayed in the display area with the direction of the object.

### Claim 6

An information processing method in an X-ray detection apparatus which detects X-rays applied to an object and generates a radiographed image of the object, the method comprising the steps of:
displaying, in a display area, a symbol which has a form corresponding to the object and for which a vector representing a direction as a reference for the symbol is defined, wherein the display area is arranged on the same side of the object as is a detection area which is configured to detect the X-rays;
changing the direction of the symbol displayed in the display area; and
outputting information concerning a direction of the vector relative to the X-ray detection apparatus in association with a radiographed image of the object, when the direction of the symbol displayed in the display area is changed in said step of changing to match the direction of the symbol displayed in the display area with the direction of the object.

### Claim 7

An X-ray detection apparatus comprising:
an X-ray sensor configured to detect X-rays transmitted through an object;
a display unit configured to display, in a display area, a symbol representing a posture of the object;
a changing unit configured to change the symbol displayed in said display area; and
an output unit configured to output information concerning the symbol in association with radiographed image data based on the X-rays detected by said X-ray sensor.

### Claim 8 (depends on 7)

The apparatus according to claim 7, wherein said output unit is communicatively connected to an X-ray image display apparatus.

### Claim 9 (depends on 7)

The apparatus according to claim 7, wherein said output unit outputs the information concerning the symbol upon superimposing the information on the radiographed image data.

### Claim 10 (depends on 7)

The apparatus according to claim 7, wherein the information concerning the symbol is added to a header of the radiographed image data.
