Apparatus and method for x-ray treatment

An X-ray treatment apparatus irradiating to a lesion of a patient lying on a couch from difference positions more than once, comprising:

• at least one marker sensor including a low energy X-ray generator and a image sensor corresponding to the low energy X-ray generator detecting a position to the couch of a marker fixed in the patient with keeping a predetermined positional relationship to the lesion and obtaining data of the lesion;
• a couch operative means changing a position and a posture of the couch;
• an X-ray source for treatment controlling a beam profile and dosage of the X-ray for treatment by deflecting electron beams;
• an X-ray sensor for treatment detecting the X-ray irradiated by the X-ray source for treatment and penetrated the lesion;
• an X-ray source for treatment operative means supporting the X-ray source for treatment, turning to the lesion and controlling the position and posture of the X-ray source for treatment;
• and
• a central processing unit calculating a profile and dosage of the X-ray for treatment corresponding to a position of the lesion specified by outputs of the marker sensor based on a treatment planning, generating control signals to the X-ray source for treatment and the operative means, modifying the treatment planning according to output data of the X-ray sensor for treatment, and generating the next control signal to the X-ray source for treatment and the operative means.
