Radiographic imaging apparatus
A radiographic imaging apparatus which has an imaging system having a radiation source to irradiate a subject with radiation and a radiation detector to detect the radiation irradiated from the radiation source, and a radiographic imaging table to arrange the subject within the imaging system includes an arm holder which supports upward arms of the subject arranged on the radiographic imaging table, and a holder supporting member which supports the arm holder.
1. A radiographic imaging apparatus which includes an imaging system having a radiation source to irradiate a subject with radiation and a radiation detector to detect the radiation irradiated from the radiation source; and a radiographic imaging table to arrange the subject within the imaging system, comprising:
a subject supporting member adapted to support the subject in a direction of the body axis;
an arm holder on which upward arms of the subject in an upright posture are placed; and
a holder supporting member which supports said arm holder and is provided at the upper end of the subject supporting member.
2. The apparatus according to claim 1 , further comprising means for relatively rotating the imaging system and the subject on the radiographic imaging table.
3. The apparatus according to claim 1 , wherein said arm holder has an arm supporting member which supports the arms of the subject from below or sides.
4. The apparatus according to claim 1 , wherein said arm holder has an arm limiting member which limits positions of the arms in a direction substantially perpendicular to a body axis of the subject.
5. The apparatus according to claim 1 , further comprising a rotating shaft which rotatably supports said arm holder through said holder supporting member, said rotating shaft being arranged substantially coaxially with a rotation center about which one of the subject and the imaging system rotates.
6. The apparatus according to claim 5 , wherein said arm holder is divided to left and right parts with respect to the body axis of the subject, and said left and right parts are rotatable in opposite directions.
7. The apparatus according to claim 1 , further comprising a grip provided above said arm holder to be held by the subject.
8. The apparatus according to claim 7 , wherein said grip includes at least one of a first grip provided on one of said holder supporting member and a subject supporting member to support the subject in a direction of the body axis and a second grip provided on said arm holder.
9. The apparatus according to claim 1 , wherein
said arm holder is fixed to the subject supporting member to support the subject in the direction of the body axis, and
the apparatus further comprises a guide member which vertically moves the subject supporting member with respect to the subject.
10. The apparatus according to claim 1 , wherein said holder supporting member is connected to one of the subject supporting member to support the subject in the direction of the body axis, a detector supporting member to support the radiation detector, and an upper portion of an imaging chamber.
11. A radiographic imaging table on which a subject is arranged within an imaging system including a radiation source to irradiate the subject with radiation and a radiation detector to detect the radiation irradiated from the radiation source, comprising:
a subject supporting member to support the subject in a direction of the body axis;
an arm holder on which upward arms of the subject in an upright posture are placed; and
a holder supporting member which supports said arm holder and is provided at the upper end of the subject supporting member.
12. The table according to claim 11 , further comprising means for relatively rotating the subject and the imaging system.
13. The table according to claim 11 , wherein said arm holder has an arm supporting member which supports the anns of the subject from below or sides.
14. The table according to claim 11 , wherein said arm holder has an arm limiting member which limits positions of the arms in a direction substantially perpendicular to a body axis of the subject.
15. The table according to claim 11 , further comprising a rotating shaft which rotatably supports said arm holder through said holder supporting member, said rotating shaft being arranged substantially coaxially with a rotation center about which one of the subject and the imaging system rotates.
16. The table according to claim 15 , wherein said arm holder is divided to left and right parts with respect to the body axis of the subject, and said left and right parts are rotatable in opposite directions.
17. The table according to claim 11 , further comprising a grip provided above said arm holder to be held by the subject.
18. The table according to claim 17 , wherein said grip includes at least one of a first grip provided on one of said holder supporting member and a subject supporting member to support the subject in a direction of the body axis and a second grip provided on said arm holder.
19. The table according to claim 11 , wherein
said arm holder is fixed to the subject supporting member to support the subject in the direction of the body axis, and
the table further comprises a guide member which vertically moves the subject supporting member with respect to the subject.
20. The table according to claim 11 , wherein said holder supporting member is connected to one of the subject supporting member to support the subject in the direction of the body axis, a detector supporting member to support the radiation detector, and an upper portion of an imaging chamber.
