Mammography apparatus
View Patent ↗A mammography apparatus includes a rotatably supported arm, an X-ray tube to generate X-rays, which is held on one end of the arm, an imaging stage which is held on the other end of the arm, an X-ray detector which detects the X-rays having passed through patient's breast and is contained in the imaging stage, and an armrest which has an armrest main body portion having a convexly curved surface, and a continuous base portion to fix the armrest main body on the arm.
1. A mammography apparatus comprising:
a rotatably supported arm;
an X-ray tube to generate X-rays, which is held on one end of the arm;
an imaging stage which is held on the other end of the arm;
an X-ray detector to detect the X-rays which have passed through a patient's breast, the X-ray detector being contained in the imaging stage; and
an armrest which has an armrest main body portion having a convexly curved surface, and a continuous base portion to fix the armrest main body on the arm, the armrest main body mounted along an outer shape of the arm.
2. A mammography apparatus according to claim 1 , wherein
the base portion has a length almost equal to length of the armrest main body portion, not to generate a gap between the armrest main body portion and the arm.
3. A mammography apparatus according to claim 1 , wherein
the armrest main body portion has a width of at least 90 mm.
4. A mammography apparatus according to claim 3 , wherein
the base portion has a width shorter than the width of the armrest main body portion.
5. A mammography apparatus according to claim 1 , wherein
the armrest main body portion has a thickness of at least 30 mm.
6. A mammography apparatus according to claim 1 , wherein
the base portion has a thickness of at least 24 mm.
7. A mammography apparatus according to claim 1 , wherein
the convexly curved surface of the armrest main body portion has a radius selected from a range of 100 to 110 mm.
8. A mammography apparatus according to claim 1 , wherein
both sides of the base portion are recessed from the armrest main body portion.
9. A mammography apparatus according to claim 1 , wherein
the base portion has one side which is recessed from the armrest main body portion, and the other side which spreads like a slope.
10. A mammography apparatus according to claim 1 , further comprising:
a compression mechanism which has a movable compression paddle to compress the patient's breast with the imaging stage; and
a foot switch to operate movement of the compression paddle;
an operator panel to operate movement of rotation of the arm, the operator panel being provided on a surface of the armrest.
11. A mammography apparatus comprising:
a rotatably supported arm;
an X-ray tube to generate X-rays, which is held on one end of the arm;
an imaging stage which is held on the other end of the arm;
an X-ray detector to detect the X-rays which have passed through a patient's breast, the X-ray detector being contained in the imaging stage; and
an armrest which is attached to the arm, and has a width of at least 90 mm and a convex surface, the armrest having an armrest main body mounted along an outer shape of the arm.
12. A mammography apparatus comprising:
a rotatably supported arm;
an X-ray tube to generate X-rays, which is held on one end of the arm;
an imaging stage which is held on the other end of the arm;
an X-ray detector to detect the X-rays which have passed through a patient's breast, the X-ray detector being contained in the imaging stage; and
an armrest which is provided along an outer shape of the arm and has a flat shape at a distal end of the armrest, the armrest having an armrest main body mounted along the outer shape of the arm.
