a position marker m r or respectively m v indicating the location of a fixed point in the patient coordinate system i at an established spot of the body surface of the patient or a 2d topogram of tissue regions organs anatomical subjects or pathological structures inside the body of the patient to be examined is generated s 2 b by means of computed or magnetic resonance tomography imaging in this 2d topogram the appertaining position marker m r or m v is placed at an established point within the area depicted in this 2d representation following this the ct pet ct or mrt assisted radiological initial examination is conducted s 3 a using specific ct mrt acquisition parameters and reconstructed 3d views or respectively 2d views presented from new projection angles of the appertaining area are calculated s 3 b using specific reconstruction parameters whereupon slice exposures generated in the framework of this initial examination and or 2d 3d reconstructions calculated with regard to the image data of these slice exposures are displayed s 3 c on the display screen ab of a screen terminal the recorded ct or respectively mrt acquisition parameters patient position coordinates and 2d 3d reconstruction parameters are then written s 4 a into a patient specific examination protocol that is stored s 4 b in a protocol file if the implementation of a computed or magnetic resonance tomography follow up examination of the patient should be planned s 5 following the ct pet ct.
