Radiation system with inner and outer gantry parts
First Claim
1. A radiation system, comprising:
- a gantry including an inner gantry part and an outer gantry part;
a radiation head mechanically supported by the inner gantry part and rotatable around a rotation axis, said radiation head comprising a treatment radiation source, arranged to direct treatment radiation to a treatment volume in an object; and
a diagnostic imaging system, comprising;
a diagnostic radiation source supported by the inner gantry part to direct diagnostic radiation onto the object, a detector unit responsive to both diagnostic radiation and treatment radiation passing through the object and outputting a signal representative of the detected radiation, and a processor, connected to the detector unit, for providing an image of the object based on the received output signal from the detector unit, wherein said inner gantry part is rotatably supported by the outer gantry part at two support locations situated, in the direction of the rotation axis, at opposite sides of the treatment volume.

Abstract
A radiation machine incorporating a diagnostic imaging system is disclosed. The invention provides a very stable design of the machine by supporting an inner gantry part, including a treatment and diagnostic radiation source and detector, by an outer gantry part at two support locations situated at opposite sides of a treatment volume in a patient to be irradiated. This stable gantry design provides a high rotation speed of the inner gantry part relative the outer gantry part around the target volume, which speed is adapted for the high resolution imaging system. Based on the obtained images, changes and developments in tumor tissue and misplacement of patient may be detected. The images may be compared to a reference image to detect any anatomical or spatial difference therebetween. Based on this comparison the settings of the radiation machine may be adapted accordingly.
