Abstract
A radiation apparatus includes a radiation source movable in translational and/or rotational degrees of freedom, and a structure adapted to support a body. The structure is provided with an opening to allow a portion of the body passing through to be exposed to at least a portion of the therapeutic radiation while in use.
Claims46
A radiation apparatus, comprising:
- a radiation source;
- and
- a structure providing a housing that encloses at least a portion of the radiation source therein, a portion of the structure being adapted to support a body and provided with an opening to allow a portion of the body passing through into the housing to be exposed to at least a portion of a radiation generated by the radiation source while in use;
- wherein said radiation source is adapted to be movable in three translational and three rotational degrees of freedom.

A radiation apparatus, comprising:
- a radiation source;
- and
- a structure providing a housing that encloses at least a portion of the radiation source therein, a portion of the structure being adapted to support a body and provided with an opening to allow a portion of the body passing through into the housing to be exposed to at least a portion of a radiation generated by the radiation source while in use;
- wherein said radiation source is adapted to be movable at least in a translational direction;
- and
- further comprising a second radiation source adapted to generate a radiation for imaging the body portion and an image detector disposed operatively opposite to the second radiation source.

A radiation apparatus, comprising:
- a radiation source;
- and
- a structure providing a housing that encloses at least a portion of the radiation source therein, a portion of the structure being adapted to support a body and provided with an opening to allow a portion of the body passing through into the housing to be exposed to at least a portion of a radiation generated by the radiation source while in use;
- wherein said radiation source is adapted to be movable at least in a translational direction;
- and
- wherein the portion of the structure has a curved-surface forming a dome configuration, and said opening is provided near the peak of the dome.
3 more elements
An apparatus for radiation treatment of breast cancer, comprising
- a structure providing a housing, a portion of the structure being adapted to support a patient in a position and provided with an opening to allow a breast of the patient passing through into the housing;
- and
- a radiation source configured to generate a therapeutic radiation to the breast, wherein at least a portion of said radiation source is enclosed inside the housing and movable in translational and rotational degrees of freedom, thereby being capable of delivering at least a portion of the therapeutic radiation to at least a portion of the breast at an adjustable distance between the radiation source and the breast, from an adjustable angle to the breast, and/or in an adjustable trajectory.
A radiation method, comprising the steps of:
- providing a radiation apparatus including a radiation source and a structure providing a housing that encloses at least a portion of the radiation source therein, a portion of the structure being configured to support a body and provided with an opening allowing a portion of the body to pass through into the housing, and the radiation source being movable in three translational and three rotational degrees of freedom;
- positioning a body on the portion of the structure allowing a portion of the body passing through into the housing;
- and
- delivering a radiation to the portion of the body using the radiation source.
1 more element
A radiation apparatus, comprising:
- a radiation source capable of generating a radiation for therapeutic treatment;
- and
- a structure providing a housing that encloses at least a portion of the radiation source therein, a portion of the structure being adapted to support a body and provided with an opening to allow a portion of the body passing through into the housing to be exposed to at least a portion of the radiation while in use;
- wherein said radiation source is adapted to be rotatable about a substantially vertical axis;
- and
- wherein the radiation source is adapted to be movable in three translational and three rotational degrees of freedom.

A radiation apparatus, comprising:
- a radiation source capable of generating a radiation for therapeutic treatment;
- and
- a structure providing a housing that encloses at least a portion of the radiation source therein, a portion of the structure being adapted to support a body and provided with an opening to allow a portion of the body passing through into the housing to be exposed to at least a portion of the radiation while in use;
- wherein said radiation source is adapted to be rotatable about a substantially vertical axis;
- and
- wherein the portion of the structure is adapted to support a patient in a substantially prone position to allow a breast of the patient passing through the opening into the housing, and the radiation source is further adapted to be rotatable about a substantially horizontal axis in about 180 degrees.
