- the compression paddle 11 against the breast If the subject is suffering from compression of the compression paddle 11 against the breast and judges that it is necessary to relieve the compression of the compression paddle 11 or to obtain a clearer projection image, the compression paddle 11 against the breast If it is deemed necessary to further enhance the compression force of the operator, the operator rotates the knob 49 of the operation shaft 48 clockwise or counterclockwise as needed to increase the compression force of the compression paddle 11 against the breast. It can be precisely relaxed or strengthened.
- the operator pivots the connecting portion 5 to the CC (Cranio-Caudal) shooting mode.
- the X-ray light source unit 6 to each shooting position according to (up-down direction shooting mode), MLO (Medio-Lateral Oblique) shooting mode (internal / external direction shooting mode), and / or ML (Medio-Lateral) shooting mode (internal / outward shooting mode).
- X-ray imaging of the breast is sequentially performed while moving the X-ray light receiving unit 8 together with FIG.
- X-ray imaging is performed in such a way that the X-ray source 7 of the X-ray light source unit 6 irradiates toward the breast and the detector 9 of the X-ray light receiving unit 8 receives X-rays transmitted through the breast, and the detector 9 Projection of the breast according to the CC imaging mode, MLO imaging mode, and / or ML imaging mode by generating an electrical signal for each position proportional to the incident amount of the received X-rays, and reading the electrical signal and position information for processing by an image processing algorithm. Create an image.
- the X-ray imaging apparatus according to the exemplary embodiment of the present invention is used as a mammography apparatus which is an X-ray apparatus for mammography has been described, but the present invention is not limited to the apparatus used for such a purpose. That is, the X-ray imaging apparatus according to the present invention is applicable to all types of X-ray imaging apparatus that acquires a projected image of a subject by performing X-ray imaging while pressing the subject, and a person of ordinary skill in the art It will be appreciated that the range extends to such types of X-ray imaging devices.
