An improved method and apparatus for producing a cross sectional image of a body using a method where the distribution of the attenuation coefficients of ionizing rays passing through the body in a cross sectional plane is derived using a convolution method, in which a plurality of convolution kernels are permanently stored for use as desired and measured data obtained and convoluted therewith after which values are added and displayed on a display device permitting different settings of image constrast to thereby harmonize the cross sectional image of the body. |
