摘要：
The present invention provides a radiotherapy apparatus (100) to generate both photon and electron beam mounted with dual KV beam ray source used for stereotactic imaging and CBCT (Cone Beam Computed Tomography) image with a greater FOV (Field Of View). The apparatus (IOO) comprises of a ring gantry (101), which includes at least two KV sources (102a and 102b), at least two movable detector (103 and 104) and a LINAC X-ray tube (106). The two movable detectors (103, 104) include a first movable detector (104) and a second movable detector (103). The second movable detector (103) has mechanism capture a half fan mode of X-ray beam of imaging radiation with a greater FOV having 250×450 mm. The half fan mode of X ray is captured by moving the second movable detector (103) or first movable detector (104) further towards the ISO centre (105) of the ring gantry (101).
