RADIOGRAPHY AND TOMOGRAPHY DEVICE Russian patent published in 2007 - IPC G01N23/222 

FIELD: inspection of internal structure by means of radiation methods.

SUBSTANCE: radiography and tomography device ha penetrating radiation source, radiation optical registration system, which has screen-converter made in form of plate, deflecting mirror, objective, photoreceiver. There is lens condenser disposed behind screen-converter. Radiation optical registration system with deflecting mirror has input projective objective disposed in series with image amplifier, scaling objective, photoreceiver made in form of CCD-array. Conical penetration radiation source is disposed in point belonging to normal line to center of screen-converter where geometrical continuations of all light tracks come together, which tracks are created in screen-converter. Device also has aid for moving tested object, which aid is made for reciprocal and rotational movement.

EFFECT: increased spatial resolution; widened functional abilities; registration of different types of penetrating radiations as quick neutrons and/or thermal neutrons, and/or X-rays and gamma rays.
