[Digital multilayer tomography. A description of the method and initial clinical results].
A set of projection images is acquired during longitudinal tomography with an image intensifier TV system. Reconstruction of tomograms in each desired plane is achieved by shifting and summing up of the digitalized projection images. Digital multilayer and conventional film tomograms mainly of the respiratory tract and skeleton have been compared in 100 patients. Image quality is comparable with both methods. Disadvantage of digital tomography is lower spatial resolution (512 x 512 matrix size); advantages include lower radiation dose, shorter study time, and facilities of digital imaging.
