Abstract
Transmission and Compton tomographic images of a few gastropods (type: Helix aspersa and Monzettee) were obtained using a tube source of x‐rays. Transmission tomographic systems consist of an x‐ray tube, image intensifier, and CCD camera. A Compton tomographic imaging system consists of an x‐ray tube, translation–rotation arrangement for sample, collimated NaI (Tl) detector, and the associated electronics for the image acquisition. Transmission images are obtained at 27 kV and 4 mA and Compton images at 40 kV and 4 mA. Images obtained in these two methods are compared and analyzed.
