Mini-tomograph for craniomandibular and maxillofacial tomography. n is tomograph comprises a frame 1, a rotating system 2, a cassette holder device 4 and an X-ray tube 5. An electrical or electronic control box controls the running and exposure time. Its originality resides in the fact that it allows tomographic sections to be taken with an X-ray source which is always present in dental surgeries; the dental radiography tube. The system is therefore economical, rapid to use by the dentist himself, without needless movement of the patient.
