It is based on the principle : under a number of angles, the x - ray attenuation in a cross section of a human body is measured by detector resulting in a set of profiles. this set of profiles is called the radon transform of the object in mathematics. the problem now is to reconstruct a two - dimensional image via inverting its radon transform
它所基於的成像原理是：人體的某個剖面在若干個角度上被x射線束照射，照射后x射線的衰減量被檢測器記錄下來，形成投影集合，數學上將這個投影集合描述為該剖面的radon變換，通過反演radon變換就能夠重建剖面的二維圖像。 -
