Dosimeter for use in radiography, in particular for intra-oral examination

Abstract

Abstract A dosimeter comprising a shielded sensor (S) to be introduced into the mouth of the patient with a radiographic film (P) and containing an X-ray/optical conversion screen (3) which excites photosensitive elements (2) which are connected, by means of a shielded cable (C), to a processing circuit (B) which compensates for the operating defects arising from the possible fall in the supply voltage (A) and which triggers an interrupt circuit (K) connected up in series with the radiographic apparatus (4) when the film (P) has received the irradiation dose regarded as optimal. The interrupt circuit (K) is combined with a safety circuit (Z) and can be connected up between the supply socket (A) and the plug of the supply cable (L) of the radiographic apparatus (4). <IMAGE>
