An intraoral x-ray sensor with embedded standard computer interface. The sensor includes a data transfer cable. In one embodiment, the cable is quad-twisted USB cable and includes two data lines, a ground line, and fillers twisted within a metallic sheath. The cable is symmetrically organized about a centerline. The symmetric cable has an improved life due to the ability to withstand mechanical stress (e.g., rotational stress). The sensor includes a processor and a housing with an inner metallization layer. The sheath is coupled to the inner metallization layer to transfer heat generated by the processor from the inner metallization layer to the sheath.
