Preliminary mechanism of sectional radiography, called the longitudinal tomography, does enhance the quality of image, but because of the different velocity of unwanted images, lying nearer to or further from axis central point, tomographic blurring does occur.
Much attention is therefore paid to improve the ability of such systems to create proper image slices which may highlight even these lesions that sectional radiography may not be able to detect.
