## Abstract

An X-ray imaging apparatus is configured so that an height-position composition element 15 sends a directive to an angle driving element 44 in an imaging element 4, and the height-position compensation element 15 corrects the height-position of the X-ray tube 42 by driving of the up-and-down driving element 44 in conjunction with the imaging region that the imaging region data recognition element 14 of the console element 1, the angle of the X-ray tube 42 is corrected so that the X-ray irradiation angle of the X-ray from the X-ray tube 42 faces downward; and when the height-position compensation element 15 corrects the height-position of the X-ray tube 42 downward, the angle of the X-ray tube 42 is corrected so that the X-ray irradiation angle of the X-ray from the X-ray tube 42 faces upward.

## Claims

### Claim 1

An X-ray imaging apparatus, comprising:
an X-ray tube;
an X-ray detection element that detects an X-ray that is irradiated from said X-ray tube and transmits through a standing subject;
a standing subject imaging stand having a lifting element that supports said X-ray detection element liftably; and
an X-ray tube shifting mechanism that changes a height-position of said X-ray tube corresponding to a height-position of said X-ray detection element to a position that faces a center portion of the imaging region that said detection element detects; and
further comprising:
an imaging region data recognition element that acquires imaging region data relative to said subject; and
a height-position compensation element that corrects the height-position of said X-ray tube in an up-and-down direction of the position facing the center portion of the imaging region in accordance with an imaging region that said imaging region recognition element recognizes.

### Claim 2 (depends on 1)

The X-ray imaging apparatus, according to claim 1, wherein:
said height-position compensation element adjusts a compensation amount of the height-position based on the height-position of said X-ray detection element.

### Claim 3 (depends on 1)

The X-ray imaging apparatus, according to claim 1, wherein:
said height-position compensation element adjusts a compensation amount of the height-position based on the height data of said subject.

### Claim 4 (depends on 1)

The X-ray imaging apparatus, according to claim 1, further comprising:
an angle compensation element that corrects an angle of said X-ray tube so that the X-ray irradiation angle of the X-ray from said X-ray tube faces downward when said height-position compensation element corrects the height-position of said X-ray tube upward; and the X-ray irradiation angle of the X-ray from said X-ray tube faces upward when said height-position compensation element corrects the height-position of the X-ray tube downward.

### Claim 5 (depends on 1)

The X-ray imaging apparatus, according to claim 1, further comprising:
a collimator that limits the upper region of the X-ray irradiation region from said X-ray tube by a blocking member when said height-position compensation element corrects the height-position of said X-ray tube upward, and limits the lower region of the X-ray irradiation region from the X-ray tube by the blocking member when the height-position compensation element corrects the height-position of said X-ray tube downward, when the height-position compensation element corrects the height-position of said X-ray tube downward.
