Medical particle irradiation apparatus
First Claim
1. A medical particle irradiation apparatus comprising:
- a rotating gantry including an irradiation unit emitting particle beams;
a first frame located within and supported by said rotating gantry such that it can rotate relative to said rotating gantry;
a second frame fixedly located opposite said first frame;
an anti-corotation unit disposed on said rotating gantry, said anti-corotation unit being in contact with both said first and second frames to prevent said first frame from rotating together with said rotating gantry during rotation of said rotating gantry; and
a flexible moving floor located between said first and second frames, said flexible moving floor being engaged with said first and second frames in such a manner as to move freely such that its bottom is substantially level and that it moves as said rotating gantry rotates.

Abstract
Disclosed is a medical particle irradiation apparatus comprising a rotating gantry 1 including an irradiation unit 4 emitting particle beams; an annular frame 16 located within and supported by the rotating gantry 1 such that it can rotate relative to the rotating gantry 1; an annular frame 15 fixedly located opposite the annular frame 16; an anti-corotation mechanism 34 being in contact with both the annular frames 16 and 15 to prevent the annular frame 16 from rotating together with the rotating gantry 1 during rotation of the rotating gantry 1; and a flexible moving floor 17 interposed between the annular frames 15 and 16, the flexible moving floor 17 being engaged with the annular frames 15 and 16 in such a manner as to move freely such that its bottom is substantially level and that it moves as the rotating gantry rotates.

7. A medical particle irradiation apparatus comprising:
-
a rotating gantry including an irradiation unit emitting particle beams;
a first frame located within and supported by said rotating gantry such that it can rotate relative to said rotating gantry;
a second frame fixedly located opposite said first frame;
an anti-corotation unit disposed on said rotating gantry, said anti-corotation unit being in contact with both said first and second frames to keep the positions of said first and second frames, located opposite each other, substantially unchanged regardless of the rotation of said rotating gantry; and
a flexible moving floor located between said first and second frames, said flexible moving floor being engaged with said first and second frames in such a manner as to move freely such that its bottom is substantially level, that it forms therein a therapy room into which a therapy bed is slid and that it moves as said rotating gantry rotates. - View Dependent Claims (8, 9, 10, 11, 12)

13. A medical particle irradiation apparatus comprising:
-
a rotating gantry including an irradiation unit emitting particle beams;
a first frame located within and supported by said rotating gantry such that it can rotate relative to said rotating gantry;
a second frame fixedly located opposite said first frame;
a frame position retaining unit disposed on said rotating gantry and being in contact with both said first and second frames, said frame position retaining unit moving in the circumferential direction of said second frame as said rotating gantry rotates; and
a flexible moving floor located between said first and second frames, said flexible moving floor being engaged with said first and second frames in such a manner as to move freely such that its bottom is substantially level, that it forms therein a therapy room into which a therapy bed is slid and that it moves as said rotating gantry rotates, wherein said frame position retaining unit is disposed on said rotating gantry such that said frame position retaining unit itself can rotate.

14. A medical particle irradiation apparatus comprising:
-
a rotating gantry carrying an irradiation unit emitting particle beams;
a first ring member located within and supported by said rotating gantry such that it can rotate relative to said rotating gantry;
a second ring member fixedly located across a path of said particle irradiation unit moving in the circumferential direction of said first ring member, from said first ring member;
a position retaining unit disposed on said rotating gantry, said position retaining unit being in contact with both said first and second ring members to keep the positions of said first and second ring members in the circumferential direction substantially unchanged regardless of the rotation of said rotating gantry;
a moving floor guide unit disposed on each of said first and second ring members, said moving floor guide unit having a substantially level portion at the bottom; and
a flexible moving floor located between said first and second ring members, said flexible moving floor moving as said rotating gantry rotates while being guided by the respective moving floor guide units disposed on said first and second ring members, to form therein a therapy room into which a therapy bed is slid. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. An irradiation room for particle beam therapy comprising:
-
a first ring member located within and relatively rotatably supported by a rotating gantry carrying an irradiation unit emitting particle beams;
a second ring member fixedly located opposite said fist ring member;
an anti-corotation unit moving in the direction of rotation of said rotating gantry as said rotating gantry rotates, said anti-corotation unit being in contact with both said first and second ring members to prevent said first ring member from rotating together with said rotating gantry during rotation of said rotating gantry; and
a flexible moving floor located between said first and second ring members, said flexible moving floor being engaged with said first and second frames in such a manner as to move freely such that its bottom is substantially level and that it moves as said rotating gantry rotates.
