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.
