X-ray diagnostic apparatus
View Patent ↗In order to achieve reductions in the size and weight of an arm while ensuring the strength, an X-ray diagnostic apparatus includes an X-ray generation unit, an X-ray detection unit, an arm having an arch shape which supports the X-ray generation unit and the X-ray detection unit, and at least one reinforcing member which has a higher elastic modulus than the arm and a sheet-like shape and is fixed to the arm.
1. An X-ray diagnostic apparatus comprising:
an X-ray generation unit;
an X-ray detection unit;
an arm having an arch shape which supports the X-ray generation unit and the X-ray detection unit and having a concave rail on a part of the back of the arm;
a supporting rail provided on the side of the arm to make the arm slide-able; and
reinforcing members which have has a higher elastic modulus than the arm and a sheet-like shape, are fixed to a front of the arm and to the left and right of the concave rail on the back of the arm and do not surround the arm.
2. The X-ray diagnostic apparatus of claim 1 , wherein the reinforcing member is fixed to an inner surface of the arm.
3. The X-ray diagnostic apparatus of claim 2 , wherein the reinforcing member is provided so as to extend from a position between the X-ray detection unit and the center of the arm to a position immediately below the X-ray generation unit.
4. The X-ray diagnostic apparatus of claim 2 , wherein the reinforcing members are provided both on the inner surface of the arm and the outer surface of the arm.
5. The X-ray diagnostic apparatus of claim 2 , wherein the reinforcing members are provided both on the inner surface of the arm and a side surface of the arm.
6. The X-ray diagnostic apparatus of claim 2 , wherein the reinforcing member is attached to an upper surface of the arm.
7. The X-ray diagnostic apparatus of claim 1 , wherein the reinforcing member is fitted in a recess portion of the arm.
8. The X-ray diagnostic apparatus of claim 1 , wherein the reinforcing member is embedded in the arm.
9. The X-ray diagnostic apparatus of claim 1 , wherein the reinforcing member covers the inner surface and part of a side surface of the arm.
10. The X-ray diagnostic apparatus of claim 1 , wherein the reinforcing member is fixed to the arm with an adhesive.
11. The X-ray diagnostic apparatus of claim 1 , wherein the reinforcing member is fixed to the arm with a screw.
12. The X-ray diagnostic apparatus of claim 1 , wherein the reinforcing member is made of a carbon fiber reinforced resin or a glass fiber reinforced resin, and the arm is made of an aluminum alloy or a magnesium alloy.
13. The X-ray diagnostic apparatus of claim 1 , wherein the reinforcing member has a higher longitudinal elastic modulus than the arm.
14. The X-ray diagnostic apparatus of claim 1 , wherein the arm has a C shape.
15. The X-ray diagnostic apparatus of claim 1 , further comprising:
a first support portion which rotatably supports the arm;
a second support portion which rotatably supports the first support portion; and
a floor support portion which swingably supports the second support portion.
16. The X-ray diagnostic apparatus of claim 1 , further comprising:
a first support portion which rotatably supports the arm;
a second support portion which rotatably supports the first support portion; and
a ceiling support portion which swingably supports the second support portion.
17. The X-ray diagnostic apparatus of claim 1 , wherein the reinforcing member consists of one member having a u-shaped cross section attached to the inner surface of arm and side surfaces of the arm.
18. An X-ray diagnostic apparatus comprising:
an X-ray generation unit;
an X-ray detection unit;
an arm having an arch shape which supports the X-ray generation unit and the X-ray detection unit; and
at least one reinforcing member consisting of one member which has a higher elastic modulus than the arm and a sheet-like shape, and is attached to a surface of the arm only on a side that faces an isocenter of the X-ray diagnostic apparatus.
19. An X-ray diagnostic apparatus comprising:
an X-ray generation unit;
an X-ray detection unit;
an arm having an arch shape which supports the X-ray generation unit and the X-ray detection unit; and
a reinforcing member consisting of a first member which has a higher elastic modulus than the arm and a sheet-like shape and is attached to an inner surface of the arm, a second member which has a higher elastic modulus than the arm and a sheet-like shape and is attached to a first side surface of the arm, and a third member which has a higher elastic modulus than the arm and a sheet-like shape and is attached to a second side surface of the arm, the first, second and third members being separate from each other.
