The emission radiation source (1), as for especially x-ray source, portable plane surface (6) around being the rotary center at on, it moves vis-a-vis the object, as for this invention, in regard to the method of forming 3 dimensional tomography picture of the object, the emission radiation source (1) in order the radiation cone (2) central ray (3) to be irradiated to the object, emits radiation, passing the object, in order for the radiation where strength decreases to be irradiated, corresponding, the detector which it moves (4) distribution facilities is done on the side which is opposite to the emission radiation source, vis-a-vis the object of central ray the angle which has central ray (3) inclines vis-a-vis portable plane surface (6)The way movement is done.< Selective figure >Figure 2本発明は、対象の3次元断層撮影画像を生成する方法に関し、放射線源(1)、特にX線源は、対象に対して、移動平面(6)上で回転中心の周りを移動し、放射線源(1)は放射線円錐(2)の中心放射線(3)が対象に照射されるように放射線を放射し、中心放射線の対象に対して放射線源と反対の側には、対象を通過して強度の低下した放射線が照射されるように対応して移動する検出器(4)が配設され、移動平面(6)に対して中心放射線(3)がある角度傾斜するように移動が行われる。【選択図】図2
