PROBLEM TO BE SOLVED: To provide an image sensor (10) for dental intraoral radiography comprising a housing (12), an image receptor (40) and a cable connection dome (32) arranged on a back side (14) of the housing (12). SOLUTION: The back side (14) of the housing (12) has a depression (36) at least in the region between the cable connection dome (32) and an anterior side (16) of the housing (12), wherein the depression (36) falls short of reaching the anterior side (16) of the housing (12) such that an elevated region (38) is formed between the depression (36) and at least the anterior side (16) of the housing (12). A positioning device (50) is adapted for positioning an image sensor (10) according to the present invention in the mouth of a patient. The present invention provides an intraoral sensor that enables good patient cooperation, thus making it possible to take high quality dental X-ray images. COPYRIGHT: (C)2006,JPO&NCIPI
