- It has been analysed that the influence of the ratio focal spot size to object ( f / d) to radiograph magnification ( M ) That analysis has done with the object shape like a coin made from iron which different diameter and variation focal spot size. The experiment has done on two condition that the distance of the object to the film, at 0 cm ( object stick the film ) and 45 cm, with the tension tube 50 kV current tube 100 mA and time 0,04 s. The experiment showed that the increasing ( f / d)wasn’t accompanied the increasing of (M) when the distance of the object to the film is 0 cm ( b=0 ) but when the distance is more than 0 (b>0) it will be resulted in the increasing of ( f / d) rate which is companied with in the increasing of (M).
