ABSTRACT:
The radiation source of a fan-beam X-ray scanner is adjustable relative to the body to be examined so that the beam exactly covers the body. Use can be made of the radiation which passes besides the body for adjustment of the optimum distance. The variation of the enlargement factor which is caused by adjustment is recorded and is applied to an arithmetic unit for use in calculating the absorption values.
