Paper Abstract

The problem of 3-D visualization of biomedical objects attracts increasing attention of medical specialists. Although tomographic techniques are advanced methods of volume representation, they are hard to apply in X-ray and ultrasound diagnostics. The reasons are well discussed in the literature. The computerized transverse axial scanning tomography opened a new field in X-ray diagnostics, and it was thought that the same principle could be applied also to ultrasonic diagnostics, even in two different ways. In the first case, ultrasound transmission tomograms of attenuation (UTTAR), while in the second case, ultrasonic transmission tomograms of velocity reconstruction (UTTVR) are formed. However, as long as X rays are used, diffraction and scattering problems are less severe than when ultrasonic waves are the information carriers. These image degradation effects issuing from the interaction of the ultrasonic beam with the tissue could be compensated for without the need of a computer if the reconstruction is performed optically and suitable filters and lenses illuminated by coherent light are used.
